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 Optimus is already benefiting investors, top Wall Street firm says
Piper Sandler has updated its detailed valuation model for Tesla (NASDAQ: TSLA), concluding that at recent share prices around $400–$420, investors are essentially acquiring the company’s ambitious Optimus humanoid robot project at no extra cost.
Tesla Optimus is already benefiting investors from a fiscal standpoint, at least that is what Alexander Potter at Piper Sandler, a top Wall Street firm covering the company, says.
Piper Sandler has updated its detailed valuation model for Tesla (NASDAQ: TSLA), concluding that at recent share prices around $400–$420, investors are essentially acquiring the company’s ambitious Optimus humanoid robot project at no extra cost.
Analyst Alexander Potter, in the firm’s latest “Definitive Guide to Investing in Tesla,” built a comprehensive framework covering 17 separate product lines.
This granular approach values Tesla’s core businesses—including electric vehicles, energy storage, Full Self-Driving (FSD) software, in-house insurance, Supercharging network, and a standalone robotaxi operation—at approximately $400 per share, without assigning any value to Optimus or related inference-as-a-service opportunities.
“At $400/share, we think investors can buy Optimus for ‘free,’” Potter stated in the note. Piper Sandler maintained its Overweight rating on Tesla shares and a $500 price target, which implicitly attributes roughly $100 per share to the robot-related businesses— a figure the analyst views as potentially conservative.
The updated model incorporates elements often overlooked by other sell-side analysts, such as detailed forecasts for Tesla’s insurance operations, Supercharger revenue, and a distinct valuation for the robotaxi business separate from FSD software licensing. It also accounts for Tesla’s 2025 CEO compensation plan for the first time.
Potter acknowledged that his estimates for 2026 and 2027 fall below Wall Street consensus, citing factors like declining deliveries from certain discontinued models and reduced regulatory credit income.
However, he expressed limited concern, noting that traditional vehicle delivery metrics are expected to matter less over time as FSD subscriber growth and robotaxi deployment metrics gain prominence. On Optimus specifically, Potter suggested the humanoid robot program, combined with inference services, “arguably will be worth more than Tesla’s other businesses combined,” though the firm has not yet produced formal long-term forecasts for these segments.
Tesla shares have traded near the $400 range in recent sessions, reflecting ongoing investor focus on the company’s autonomous driving progress and expansion into robotics and AI. The Optimus project remains in early development stages, with Tesla aiming to deploy the robots initially for internal factory tasks before broader commercial applications.
This Piper Sandler analysis highlights the growing emphasis among some investors and analysts on Tesla’s long-term technology platform potential beyond its current automotive and energy businesses.
As with any forward-looking valuation, outcomes will depend on execution timelines, technological breakthroughs, regulatory approvals for autonomous systems, and market adoption of humanoid robotics—areas that carry significant uncertainty and execution risk.
The note underscores a common theme in Tesla coverage: differing views on how to quantify emerging high-growth opportunities like robotics within the company’s overall enterprise value. Investors are advised to consider their own risk tolerance and conduct thorough due diligence regarding these speculative elements.

Tesla confirmed HW3 can’t do Unsupervised FSD but there’s more to the story
Tesla confirmed HW3 vehicles cannot run unsupervised FSD, replacing its free upgrade promise with a discounted trade-in.
Tesla has officially confirmed that early vehicles with its Autopilot Hardware 3 (HW3) will not be capable of unsupervised Full Self-Driving, while extending a path forward for legacy owners through a discounted trade-in program. The announcement came by way of Elon Musk in today’s Tesla Q1 2026 earnings call.

The history here matters. HW3 launched in April 2019, and Tesla sold Full Self-Driving packages to owners on the understanding that the hardware was sufficient for full autonomy. Some owners paid between $8,000 and $15,000 for FSD during that period. For years, as FSD’s AI models grew more demanding, HW3 vehicles fell progressively further behind, eventually landing on FSD v12.6 in January 2025 while AI4 vehicles moved to v13 and then v14. When Musk acknowledged in January 2025 that HW3 simply could not reach unsupervised operation, and alluded to a difficult hardware retrofit.
The near-term offering is more concrete. Tesla’s head of Autopilot Ashok Elluswamy confirmed on today’s call that a V14-lite will be coming to HW3 vehicles in late June, bringing all the V14 features currently running on AI4 hardware. That is a meaningful software update for owners who have been frozen at v12.6 for over a year, and it represents genuine effort to keep older hardware relevant. Unsupervised FSD for vehicles is now targeted for Q4 2026 at the earliest, with Musk describing it as a gradual, geography-limited rollout.
For HW3 owners, the over-the-air V14-lite update is welcomed, and the discounted trade-in path at least acknowledges an old obligation. What happens next with the trade-in pricing will define how this chapter ultimately gets written. If Tesla prices the hardware path fairly, acknowledges what early adopters are owed, and delivers V14-lite on the June timeline it committed to today, it has a real opportunity to convert one of the longest-running sore subjects among early adopters into a loyalty story.

Tesla (TSLA) Q1 2026 earnings results: beat on EPS and revenues
Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a miss on vehicle deliveries for the first quarter, delivering 358,023 vehicles and building 408,386 cars during the three-month span.
As Tesla transitions more toward AI and sees itself as less of a car company, expectations for deliveries will begin to become less of a central point in the consensus of how the quarter is perceived.
Nevertheless, Tesla is leaning on its strong foundation as a car company to carry forward its AI ambitions. The first quarter is a good ground layer for the rest of the year.
Tesla Q1 2026 Earnings Results
Tesla’s Earnings Results are as follows:
- Non-GAAP EPS – $0.41 Reported vs. $0.36 Expected
- Revenues – $22.387 billion vs. $22.35 billion Expected
- Free Cash Flow – $1.444 billion
- Profit – $4.72 billion
Tesla beat analyst expectations, so it will be interesting to see how the stock responds. IN the past, we’ve seen Tesla beat analyst expectations considerably, followed by a sharp drop in stock price.
On the same token, we’ve seen Tesla miss and the stock price go up the following trading session.
Tesla will hold its Q1 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.
