From Aerospace-Grade to Automotive-Grade: The Transformation of the Industry

In August 2026, the National Intellectual Property Administration publicly disclosed a significant patent - "Titanium Alloy Powder Materials for Additive Manufacturing, Formed Parts and Their Preparation Methods, and Automobiles", with the publication number CN122466309A.

This comprehensive patent covering powder materials, formed parts, preparation processes, and automotive applications marks that Xiaomi Automobile Technology Co., Ltd. has officially entered the 3D printing field of automotive titanium alloys. For titanium industry peers, the significance of this matter goes far beyond the technical reserves of a single carmaker - it may be opening the door for titanium alloys to move from "rare and high-end" to the "trillion-dollar civilian market".

1. Breaking through the cost barrier: The "key move" of customized titanium powder formula
Titanium alloys are known as the "space metal", with undeniable advantages such as high strength, lightweight, corrosion resistance, and anti-fatigue. They have long been standard in the aerospace field. However, in the civilian automotive field, titanium alloys have always been difficult to be widely implemented - material costs are high, forming is difficult, and the economic efficiency of mass production is poor. These three bottlenecks have held the industry back for over a decade.

The core breakthrough of Xiaomi's patent precisely targets the first bottleneck: the material side.

According to the patent announcement content, the new titanium alloy powder is based on metallic titanium, precisely proportioning key elements such as aluminum, vanadium, and innovatively adding trace amounts of nitrogen to optimize the material's microstructure. The specific composition ratio is: 5-7% by weight of Al, 3-5% by weight of V, 0.02-0.35% by weight of N, and the remainder being Ti.

The value of this formula lies in - it does not simply use aerospace titanium alloys directly, but specifically optimizes the forming for 3D printing processes. After being formed through additive manufacturing technology, the finished product achieves comprehensive improvements in core mechanical indicators such as strength, toughness, corrosion resistance, and anti-fatigue, while effectively reducing the defect rate during the printing process.

Balancing performance and mass production economy - these six words are the key to truly breaking the cost barrier of high-end titanium alloy materials in the automotive field.

2. The "hardcore answer" for lightweighting: Data speaks for itself
Titanium alloy 3D printing installed in vehicles, performance improvement is real.

Industry cases have verified the potential: Compared with the casting version, the weight of the additive manufacturing titanium brake caliper has been reduced by more than 30%; Compared with aluminum or iron castings, the weight of the titanium door hinge has been reduced by approximately 50%. Bugatti's 3D-printed titanium alloy eight-piston brake caliper has a total weight of only 2.9 kg, reducing the weight by over 40% compared to the aluminum version.

These numbers represent a systematic leap in vehicle performance. For electric vehicles, every kilogram of weight reduction is a multiple enhancement in range, energy consumption, and handling. This high-performance titanium alloy formed part can widely cover key structural components of the vehicle body, chassis brake parts, suspension systems, and high-end interior precision components, etc.

What is more noteworthy is that titanium alloy 3D printing is moving from "exclusive for supercars" to "feasible for mass production". Information from the TCT Asia Expo in 2026 indicates that the cost of titanium alloy 3D printing has already been lower than traditional precision casting, and achieving hundreds of kilograms of lightweighting for automotive mass production is no longer a fantasy.

3. Global competition: A track accelerating
Xiaomi is not an isolated case - this is a global industrial race.

From market data, the global market for 3D printing titanium and titanium alloy materials in 2025 is approximately 967 million US dollars, and is expected to reach 1817 million US dollars in 2032. The automotive industry accounts for approximately 29% of the demand share, mainly used for prototype manufacturing and lightweight structural components. The global market for 3D-printed metal powders for automobiles is expected to reach 156 million US dollars in 2025 and will increase to 1062 million US dollars by 2032, with a compound annual growth rate of 32%.

International players have already made their moves. Researchers at the Royal Melbourne Institute of Technology in Australia have developed a new type of titanium alloy suitable for 3D printing, with a cost approximately 33% lower than the currently widely used titanium alloy. Bugatti has applied 3D-printed titanium alloy exhaust tailpipes to models such as Chiron Pur Sport. High-performance machinery manufacturer Vittori has joined forces with partners to promote the large-scale mass production of titanium alloy 3D-printed components.

Domestically, enterprises such as Piletech are also actively following suit. At the Formnext 2025 exhibition, they showcased application results such as titanium alloy automotive door hinges. BYD Youtong U9X even made 3D-printed bodies and titanium alloy calipers its core selling points, with a global production limit of 30 units and an initial price of 13 million yuan. All were sold out during the Beijing Auto Show.

IV. Industry Signals: The "Civilian Timeline" of Titanium Alloy is Accelerating
This patent layout by Xiaomi reflects deeper industry signals.

Signal 1: Competition has expanded from "automobile manufacturing" to "material manufacturing". Currently, the competition in the new energy vehicle industry has gradually extended from vehicle assembly and intelligent configuration to basic fields such as upstream materials and core processes. Previously, most high-end titanium alloy automotive manufacturing technologies and materials were monopolized by overseas enterprises, and domestic auto manufacturers had relatively scarce self-developed technologies. Xiaomi's entry means that domestic auto manufacturers are moving from "buying materials" to "manufacturing materials".

Signal 2: Titanium Alloy Moves from "Aerospace Grade" to "Vehicle Grade". As the cost of 3D-printed titanium alloy continues to decline - from 600 yuan per kilogram in 2023-2024 to below 300 yuan per kilogram, a reduction of 50% - titanium materials are gradually moving from high-end fields such as aerospace and deep-sea equipment to large-scale production scenarios in new energy vehicles.

Signal 3: The material matrix is taking shape. Xiaomi's car before has already established a technical barrier in the integrated die-casting field through its self-developed "Titanium Alloy". This entry into the titanium alloy 3D-printing sector means that Xiaomi is building a complete lightweight material matrix from aluminum alloy die-casting to titanium alloy additive manufacturing - the former covers large structural components, and the latter targets precise and complex parts, forming a complementarity.
