Tesla patents aluminum “spray quench” process for molecular-level strengthening
Tesla has submitted a patent that describes a new, more effective cooling process for manufacturing high-strength aluminum components to be used in its product line.
The patent entitled, “System and Method for Facilitating Pulsed Spray Quench of Extruded Objects”, describes a quenching process that aims to increase the strength, rigidity, and energy absorption of aluminum alloy components. A multi-way spray nozzle system would cool extruded aluminum with an atomized spray of liquid.
“A system includes a billet die at a proximal end configured to accept a billet and form an extrudate, a quench chamber located adjacent to the billet die for receiving the extrudate and comprising at least one pulsed width modulation (PWM) atomizing spray nozzle and a control module in communication with the at least one PWM atomizing spray nozzle and configured to independently control a liquid pressure, a gas pressure, a spray frequency, a duty cycle and flow rate of each at least one PWM atomizing spray nozzle,” reads the patent abstract.
Vehicles today use 6XXX aluminum alloys, which make up the front and rear bumpers, side and back steps, and knee bolsters of a car, the Kobelco Technology Review stated. Tesla also indicates within the patent that it uses 6XXX alloys for its vehicles. After these parts are extruded, they enter a quenching process, which is simply the process of cooling the metal after it has been heated.
Currently, Tesla utilizes a quenching process that involves cooling recently extruded aluminum alloys by soaking the parts in water. This process of quenching is recognized as “quick cooling.” While other cooling means are available, such as air cooling and furnace cooling, soaking the parts in water is the most time-effective method for automotive manufacturing.

However, Tesla’s patent recognizes the adverse effects that quick cooling aluminum alloy parts can have on the structural integrity of the metal. Quick-cooling can not only lead to deformation and warping of metal parts, but things can change chemically as well.
Magnesium silicide, or Mg2Si, is present in these aluminum alloy parts, and quick cooling them can inhibit the compound’s ability to set in the metal. Without the proper setting of Mg2Si by quick-cooling the aluminum alloy in water, the metal requires a higher extrusion pressure and becomes more sensitive to heat, according to Light Metals 2014. The combination of these two properties can effectively compromise the mechanical properties of the final product, making the frame of the vehicle lose strength through the manufacturing process.
Tesla plans to utilize a multi-way spraying system to cool extruded aluminum parts, eliminating the soaking process that is used by so many manufacturers of aluminum alloy. In the patent, the company describes a quenching system that would spray newly extruded metals at varying rates depending on the size of the part. Between one half-gallon and 10 gallons of water per minute would cool the metal in question.

Two pyrometers would be placed at both the proximal and distal ends of the quench chamber. These would hold the responsibility of maintaining the metal’s temperature through the quenching process. The pyrometers would communicate with the system to ensure proper cooling temperatures, making sure the aluminum does not cool too quickly, allowing the Mg2Si to set. In conjunction with the temperature control, spray frequency, liquid pressure, gas pressure, and flow rate will also be monitored to ensure maximum strength after extradition is complete.
Tesla’s recognition of the flaws in quick-cooling extruded metals indicates the company’s realization that increased strength of a car’s frame could improve with a more efficient cooling technique.
In the teardown of the Model Y, Sandy Munro complimented Tesla’s use of what he called the “aluminum rear crush plate.” The piece is located at the trunk hatch and is designed to fold in the event of a rear-impact. The part saves the sides of the body from being compromised in a crash, which can ultimately total the vehicle if the chassis bends excessively.

While the crush plate is durable and prevents excessive damage to the body of the Model Y, the quick-cooling process used during manufacturing could ultimately make the crush plate less sustainable than what it could be. Not to mention, the front bumper, rear bumper, side and back steps, and knee bolsters are also made of aluminum. Using a different cooling technique could eventually lead to an even safer Tesla vehicle, which already has many five-star crash safety ratings from several organizations located around the world.

Tesla welcomes Chipotle President Jack Hartung to its Board of Directors
Tesla announced the addition of its new director in a post on social media platform X.

Tesla has welcomed Chipotle president Jack Hartung to its Board of Directors. Hartung will officially start his tenure at the electric vehicle maker on June 1, 2025.
Tesla announced the addition of its new director in a post on social media platform X.
Jack Hartung’s Role
With Hartung’s addition, the Tesla Board will now have nine members. It’s been a while since the company added a new director. Prior to Hartung, the last addition to the Tesla Board was Airbnb co-founder Joe Gebbia back in 2022. As noted in a Reuters report, Hartung will serve on the Tesla Board’s audit committee. He will also retire from his position as president and chief strategy officer at Chipotle, and transition into a senior advisor’s role at the restaurant chain, next month.
Hartung has had a long career in the Mexican grill, joining Chipotle in 2002. He held several positions in the company, most recently serving as Chipotle’s President and Chief Strategy Officer. Tesla highlighted Hartung’s accomplishments in a post on its official account on X.
“Over the past 20+ years under Jack’s financial leadership, Chipotle has seen significant growth with over 3,700 restaurants today across the United States, Canada, the United Kingdom, France, Germany, Kuwait and the United Arab Emirates. Jack was named ‘CFO of the Year’ by Orange County Business Journal and Best CFO in the restaurant category by Institutional Investor,” Tesla wrote in its post on X.
Tesla Board and Musk
Tesla is a controversial company with a controversial CEO, so it is no surprise that the Board of Directors tend to get flak as well. Two weeks ago, for example, Tesla Board Chair Robyn Denholm slammed The Wall Street Journal for publishing an article alleging that company directors had considered a search for a potential successor to Elon Musk. Denholm herself has also been criticized for offloading her TSLA shares.
More recently, news emerged suggesting that the Tesla Board of Directors had formed a special committee aimed at exploring a new pay package for CEO Elon Musk. The committee is reportedly comprised of Tesla board Chair Robyn Denholm and independent director Kathleen Wilson-Thompson, and they would be exploring alternative compensation methods for Musk’s contributions to the company.

Rivian stock rises as analysts boost price targets post Q1 earnings
Rivian impressed with smaller-than-expected losses & strong revenue, pushing analysts to raise price targets.

Rivian stock is gaining traction as Wall Street analysts raise price targets following the electric vehicle (EV) maker’s first-quarter earnings report. Despite a dip after the announcement, optimism surrounds Rivian’s cost control and upcoming lower-priced cars.
Last week, Rivian reported a better-than-expected Q1 gross profit, surpassing Wall Street’s forecasts with adjusted losses of $0.48 per share against expectations of $0.92 per share. The company also reported a revenue of $1.24 billion compared to the $1.01 billion anticipated.
However, the EV automaker cut its 2025 delivery forecast and capital spending due to President Donald Trump’s tariffs. It explained that it is “not immune to the impacts of the global trade and economic environment.” RIVN stock dropped nearly 6% post-earnings, closing at $12.72 per share.
Wall Street remains upbeat about Rivian, citing progress toward launching lower-priced vehicles in 2026 and effective cost management. On Monday, Stifel analyst Stephen Gengaro raised his RIVN price target to $18 from $16, maintaining a “Buy” rating. He highlighted Rivian’s “solid progress” toward key milestones.
Conversely, Bernstein’s Daniel Roeska gave RIVN a “Sell” rating. However, Roeska also lifted his Rivian price target to $7.05 from $6.10, acknowledging “better” Q1 results. He warned that profitability remains distant and hinges on multiple product launches by the decade’s end.
Overall, Wall Street’s average price target for RIVN climbed from $14.18 to $14.31, a modest 13-cent increase reflecting positive sentiment. About one-third of analysts covering Rivian rate it a Buy, compared to the S&P 500’s average Buy-rating ratio of 55%.
On Monday, Rivian stock rose 2.7% to $14.64, slightly trailing the S&P 500 and Dow Jones Industrial Average, which gained 3.3% and 2.8%, respectively. The uptick may also stem from broader market gains tied to news of a temporary U.S.-China tariff suspension.
As Rivian navigates trade challenges and scales production at its Illinois factory, its Q1 performance and analyst support signal resilience. With lower-priced EVs on the horizon, Rivian’s strategic moves could bolster its position in the competitive EV market, offering investors cautious optimism for long-term growth.

Tesla (TSLA) poised to hit $1 trillion valuation again amid reports of Trump China deal
TSLA stock was up about 8% at $322.56 per share on Monday’s premarket.

Tesla shares (NASDAQ:TSLA) are on a tear on Monday’s premarket amidst reports that the United States and China have agreed to significantly roll back tariffs on each other’s goods for an initial 90-day period.
As of writing, the premarket price of TSLA shares suggests that the electric vehicle maker might end Monday with a $1 trillion valuation once more.
Tesla and China
TSLA stock was up about 8% at $322.56 per share on Monday’s premarket. As noted in a report from Barron’s, these prices suggest that the company could achieve a trillion-dollar valuation again, a level not seen since late February. Similar to Tesla, the S&P 500 and the Dow Jones Industrial Average were also up 2.8% and 2.1%, respectively, on Monday’s premarket.
The United States and China’s decision to roll back its tariffs would likely be appreciated by CEO Elon Musk. Despite working for the Trump administration’s Department of Government Efficiency (DOGE), and despite Tesla being least affected by the Trump administration’s tariffs due to its strong domestic supply chains in the United States, China, and Europe, Musk has noted that he is a supporter of non-predatory tariffs.
The United States and China’s Agreement
In a joint statement from the United States and China posted on the White House’s official website, the two countries agreed to lower reciprocal tariffs on each other by 115% for 90 days. This means that the United States will temporarily lower its overall tariffs on Chinese goods from 145% to 30%, as noted in an ABC 12 report. China, on the other hand, will also lower its tariffs on American goods from 125% to 10%.
The talks were led by Chinese Vice Premier He Lifeng and Treasury Secretary Scott Bessent and U.S. Trade Representative Jamieson Greer, as per the joint statement. Bessent shared his thoughts about the matter in a comment in Geneva. “The consensus from both delegations is neither side wants to be decoupled, and what have occurred with these very high tariffs … was an equivalent of an embargo, and neither side wants that. We do want trade. We want more balance in trade. And I think both sides are committed to achieving that,” he said.
A spokesperson from China’s Commerce Ministry also shared a statement about the matter. As per the spokesperson, the deal was an “important step by both sides to resolve differences through equal-footing dialogue and consultation, laying the groundwork and creating conditions for further bridging gaps and deepening cooperation.”
