Three "Usefulness" of Titanium Alloy in Humanoid Robots
In July 2026, two major industrial events facing each other across the ocean pointed to a clear signal: the first year of mass production of humanoid robots officially started.
In Shanghai, the 2026 World Artificial Intelligence Conference is about to kick off. The total exhibition area will exceed 100,000 square meters for the first time. More than 1,100 companies will bring more than 3,000 exhibits, and a variety of humanoid robots and AI dexterous hands will make their world premieres. The Ministry of Industry and Information Technology disclosed on the eve of the conference that the annual output of humanoid robots this year is expected to exceed 100,000 units, while domestic shipments in 2025 will only be about 12,000 units.
On the other side of the ocean, Tesla has issued guidelines for the procurement of Optimus humanoid robot parts to suppliers, requiring production capacity to reach 1,000 units in the first week of September and increase to 2,000 to 2,500 units by the end of the year. Musk even said: If the production capacity target at the end of the year cannot be met, the procurement team will be replaced as a whole. To this end, Tesla dismantled the Model S and Model X production lines in just 46 days to make room for mass production of the Optimus Gen 3.
Two things point to the same signal: in 2026, the first year of mass production of humanoid robots will officially start. In this industrial wave, a repeatedly mentioned name is moving from behind the scenes to the front stage-titanium alloy.
I. Why do humanoid robots "must be titanium"?
A humanoid robot usually needs to be equipped with 14 to 16 transmission joints, and these core components directly determine the motion accuracy, flexibility and load capacity of the whole machine. Since then, the precision machining technology of such core components has been monopolized by overseas enterprises. The intervention of titanium alloy is breaking this pattern.
Lightweight, allowing robots to "run faster and stand longer". The density of titanium alloy is only 60% of that of steel, but its strength is comparable to that of steel. Taking Tesla Optimus Gen 3 as an example, its hip and knee joints use Ti-6Al-4V titanium alloy gear sets, combined with 3D printed hollow structure, the weight of a single joint component is 40%, and the fatigue life is increased to three times that of stainless steel. According to industry data, the amount of titanium alloy used for a single humanoid robot is about 3 to 5 kilograms, mainly concentrated in bionic joint gear sets, bionic spine support frames and sensor packaging structures. Another study pointed out that the titanium alloy consumption of Optimus Gen3 has increased from 1.2 kg of Gen2 to 4.5 kg, and its proportion in the material cost of the whole machine has increased from 7% to 19%.
High intensity makes the robot "bearable and reliable". The spinal support frame of Boston Dynamics Atlas V11 adopts a mesh titanium alloy frame, which increases the overall rigidity by 18% under a load capacity of 25kg. The gradient porous titanium alloy of the Harbin Institute of Technology team has increased the energy absorption efficiency by 32%, and has entered the stage of intelligent robot prototype verification.
Fatigue resistance, so that the robot "can withstand toss". Robots need to move repeatedly and work at high frequency, and the fatigue resistance of materials directly determines the life of equipment. Domestic medical-grade titanium alloys have passed the 2 million cycle tests of UBTECH Walker X. Titanium alloy can operate stably in the extreme range of-40 °C to 120 °C. Whether it is the acid and alkali of dust in industrial workshops or the rainy and snowy weather of outdoor inspections, it can calmly deal with it.
As an industry observer said: "A revolution that is harder than algorithms is quietly happening in bones and materials."
II. The dual engines of policy and market are roaring
The outbreak of the humanoid robot track is by no means accidental.
Overweight on the policy side. In December 2024, China's "Guiding Opinions on Humanoid Robot Innovation" listed "titanium alloy precision forming technology" as one of the top ten key projects for the first time. In June 2026, the Ministry of Industry and Information Technology and the State-owned Assets Supervision and Administration Commission of the State Council jointly launched the "Special Action for Humanoid Robots and Embodied Intelligence Real-Scene Training", anchoring the three major directions of industry, service, and special, and requiring the formation of 10,000-level scale landing capabilities by the end of 2026. At the local level, many provinces and cities have set up special funds to support the research and development of key processes such as titanium alloy 3D printing, and promote the rapid implementation of new materials in the field of humanoid robots.
Market demand is blowout. According to statistics from the China Nonferrous Metals Industry Association, in the first quarter of 2025, domestic orders for titanium alloys for robots surged by 217% year-on-year, and the monthly production capacity exceeded 80 tons, a three-fold increase from the same period in 2023. Morgan Stanley has raised its humanoid robot shipment forecast twice this year, and the latest estimate is that shipments in 2026 will be about 50,000 units. Gaogong Robot Industry Research Institute predicts that domestic shipments of humanoid robots will reach 62,500 units in 2026.
In terms of market size, according to the Market Research Future report, the global titanium alloy market for humanoid robots is expected to reach 18.7 billion yuan in 2030, an increase of nearly 14 times from 1.28 billion yuan in 2024, with a compound annual growth rate of 49.3%. From 1.28 billion to 18.7 billion-a tens of billions-level track is taking shape.
III. The upstream and downstream of the industrial chain are running into the market
In the face of opportunities, all parties in the industry chain have taken action.
Upstream material end. The medical-grade titanium alloy developed by Western Superconductor has passed the verification of leading enterprises, making a breakthrough in the field of robot joint materials. Chujiang New Materials invested 850 million yuan to build a grade titanium alloy production line, and actively deployed the robot track. Jintian Technology and Sany Robot have jointly tackled low-cost titanium alloy forging technology to push down material costs. Enterprises such as Zhongke Sannai have also accelerated the pace of research and development in the field of high-performance titanium alloys, and a number of material verification projects are in progress.
Midstream manufacturing end. At the Formnext Shenzhen 3D Printing Exhibition in 2026, the 3D printing solution with titanium alloy and high-strength aluminum alloy as the core materials will become the focus. With the bionic bone trabecula and hollow structure design, the weight of the printed product can be reduced by up to 60%. Everwin Precision's total shipments of robotic components from January to April 2026 have exceeded 380,000 pieces. Zhiyuan Robotics will add more than 10,000 humanoid robot production orders to the supply chain in April 2026. Xiaopeng Motors has carried out technical exchanges with the special titanium material team of Anshan Iron and Steel Beijing Research Institute, and initially reached a cooperation intention to jointly promote the mass production and adaptation of titanium alloy materials. Precision transmission companies such as Green Harmonic are also accelerating the verification and introduction of titanium alloy harmonic reducers.
From policy guidance to market explosion, from material research and development to mass production of parts, a complete titanium alloy robot industry chain is accelerating.
Conclusion
In 2026, humanoid robots are walking out of laboratories and into factories, warehouses, hospitals and thousands of households. The Ministry of Industry and Information Technology has clearly stated that efforts should be made to improve the level of core technologies such as integrated joints. The core of the integrated joint cannot bypass materials.
With the comprehensive advantages of lightweight, high strength, fatigue resistance and corrosion resistance, titanium alloy is becoming an "irreplaceable" bone material for humanoid robots. It is not only a "space metal", but also the hard core backbone of a "ground robot".
As a practitioner in the titanium material industry, we are standing on a once-in-a-lifetime industry outlet. Policy support, market demand, and technological breakthroughs-the only thing that needs to be done is to come up with better materials, better processes, and stronger production capacity to meet this trillion-dollar market that is about to explode.
The era of humanoid robots has arrived, and the era of titanium alloys has just begun.
