Xiaomi Auto has introduced Titan Alloy 2.0, a fully recycled aluminium alloy used in structural vehicle components, achieving significant carbon reduction and setting a new industry standard for sustainable materials in mass production.
Xiaomi Auto has moved to industrialise a new recycled-aluminium alloy that it says could reshape the carbon profile of high-volume vehicle production, as Chinese manufacturers come under growing pressure to cut emissions across the supply chain.
The company has launched Titan Alloy 2.0, a material made from 100% recycled aluminium and now being used in integrated die-cast rear underbody structures on its SU7 and YU7 models. Xiaomi says this is the first time a Chinese automotive brand has brought fully recycled aluminium into mass-produced structural castings of this kind, a category previously dominated by primary metal in safety-critical areas.
What gives the announcement wider significance is not simply the use of scrap-based feedstock, but the combination of recycled content, large-scale die-casting and formal emissions verification. According to Xiaomi, the alloy carries a certified carbon intensity of 1.1kgCO₂e per kilogram, around 93% below that of conventional primary aluminium. The figure has been independently assessed by the IVL Swedish Environmental Research Institute and registered in the international Environmental Product Declaration system, giving the material a level of external validation that will matter to buyers and regulators alike.
For industrial decarbonisation professionals, the appeal lies in where the material is being deployed. Rear-floor and underbody structures sit within some of the most demanding zones of a vehicle’s body-in-white architecture, where crash performance, dimensional stability and quality control are non-negotiable. Xiaomi says Titan Alloy 2.0 has been checked through X-ray inspection and reviewed by a technical committee organised by the China Machinery Industry Federation, which concluded that it meets the relevant strength and safety requirements.
The production route is also notable. Xiaomi describes a multi-stage process involving pre-treatment of recycled aluminium, smelting, chemistry adjustment, melt refinement, ingot formation and then final gigacasting. That matters because the environmental case for recycled aluminium is only part of the story: to be commercially viable in automotive structures, the material must also work reliably in highly automated, high-throughput manufacturing lines.
Xiaomi claims the switch cuts roughly 800kg of carbon dioxide per vehicle. On its own internal volume estimate of 550,000 vehicles a year, that would translate into about 450,000 tonnes of annual emissions avoided across the production base. While such figures should be treated cautiously when they come from the company itself, they are directionally consistent with the broader industry logic of replacing primary aluminium, one of the more carbon-intensive inputs in vehicle manufacturing.
The timing is also relevant. European rules are steadily tightening around product carbon disclosure and border-linked climate policy, including the bloc’s Carbon Border Adjustment Mechanism. Although passenger cars are not the mechanism’s first and simplest test case, the direction of travel is clear: emissions performance is becoming part of industrial competitiveness, not just a sustainability badge. For Chinese EV makers with export ambitions, low-carbon materials could become a strategic advantage as much as a compliance tool.
Xiaomi’s move comes as the brand continues to scale at pace. China EV DataTracker data for May 2026 showed the SU7 with 24,023 sales and the newly launched YU7 with 8,736 deliveries, underscoring the company’s shift from single-model momentum to a broader product ramp. Against that backdrop, a structural material capable of reducing emissions without compromising safety or throughput could help the manufacturer strengthen its manufacturing story as well as its market position.
For the wider auto supply chain, Titan Alloy 2.0 points to an important shift: decarbonisation is moving deeper into the metallurgy, casting and qualification stages of vehicle production, where the biggest gains may come not from visible product changes, but from re-engineering the materials themselves.

This innovation marks the first domestic use of fully recycled alloys in mass-produced integrated die-cast rear floor assemblies, eliminating the need for virgin metal in critical safety zones. The alloy achieves a certified carbon emission value of 1.1 kgCO₂e/kg, representing a 93% reduction compared to traditional primary aluminium. Independent verification by the IVL Swedish Environmental Research Institute and registration in the international EPD system validate these low-carbon metrics.
- https://english.news18a.com/news/english_271954.html – Xiaomi has announced the successful implementation of its self-developed ‘Xiaomi Titan Alloy 2.0,’ which utilises 100% recycled aluminium and is now in mass production for the integrated die-cast rear underbody of its new SU7 and YU7 vehicle models. This marks the first time a Chinese automotive brand has adopted 100% recycled aluminium alloy in integrated die-cast structural components, filling a critical gap in China’s domestic auto industry. According to an independent lifecycle assessment conducted by IVL Swedish Environmental Research Institute and verified under the international Environmental Product Declaration (EPD) system, Xiaomi Titan Alloy 2.0 achieves a carbon footprint of just 1.1 kgCO₂e per kilogram—approximately 93% lower than that of conventional primary aluminium. A technical evaluation organised by the China Machinery Industry Federation confirmed that the material meets internationally advanced standards. The evaluation committee comprised academicians in materials science and top industry experts. Each vehicle using this material reduces CO₂ emissions by approximately 800 kg—equivalent to the annual carbon sequestration of 40 trees. At an annual production volume of 550,000 vehicles, the total annual CO₂ reduction would reach about 450,000 tons, equivalent to the yearly carbon absorption of 20 million trees. Xiaomi Titan Alloy 2.0 has undergone rigorous validation across multiple vehicle models and components, including critical load-bearing structural parts like the rear underbody. It fully complies with stringent automotive requirements for mechanical properties, crashworthiness, and internal quality as assessed by X-ray inspection. The primary manufacturing process includes five-stage pre-treatment of recycled aluminium, melting, precise alloy composition adjustment, refined melt treatment, casting into 100% recycled aluminium ingots, and final integrated die-casting.

This technology achieves a 93% reduction in carbon emissions compared to traditional primary aluminium. The material is used in the manufacture of the rear floor section of the body, one of the key elements of the car’s power structure. The transition to recycled aluminium has made it possible to abandon the use of primary metal in critical safety-related areas. According to Xiaomi’s estimates, the carbon footprint of the new alloy is 1.1 kg CO₂-equivalent per kilogram of material, which is approximately 93% lower than that of traditional primary aluminium. These figures have been confirmed by the Swedish Environmental Research Institute IVL, and the material itself is registered in the international environmental declaration system EPD. The production of Titan Alloy 0 involves a six-stage technological process. After multi-stage raw material preparation, the aluminium is re-melted, its chemical composition is adjusted, and then the finished ingots are sent to the gigacasting lines. For quality control, each part undergoes X-ray inspection to detect internal defects. The design was also checked by an expert commission of the China Federation of Machinery Industry, which confirmed compliance with strength and safety requirements. Xiaomi claims that the use of the new material reduces emissions by approximately 800 kg of CO₂ per car produced. With a planned production volume of about 550,000 cars per year, the total emission reduction could reach 450,000 tons of CO₂ annually.
