Aerospace Lightweight and high-performance material solutions: Shengxi contributes to next generation aircraft innovation

As the global aviation industry faces pressure to reduce emissions (ICAO target: net zero emissions by 2050) and fuel efficiency challenges, the most lightweight materials and the most high-performance alloys become the core breakthrough in aircraft manufacturing. According to Boeing's forecast, the annual growth rate of titanium alloy demand for aviation in the next decade will reach 8%, and the market size of advanced aluminum alloy and composite materials is expected to exceed $22 billion . Shengxi Group, with its deep accumulation in the field of aerospace metal materials, provides the most professional material selection solutions for key components such as airframe structure, engine system and landing device, helping customers achieve a weight reduction of 15%-30% while ensuring the highest level of safety performance.

Core material technical advantages

1. Lightweight structural material

- High-strength aluminum alloy(such as 7050-T7451, 7075-T6) : used for wing skin, fuselage frame, fatigue performance increased by 40%

Titanium alloy(Ti-6Al-4V, Ti-5553) : suitable for landing gear, engine pressure disc, specific strength is better than traditional steel

- Magnesium alloy(AZ31B, WE43) : used in cabin structural parts, the density is only 2/3 of aluminum

2. Extreme environment weathering material

- Superalloy(Inconel 718, Hastelloy X) : meets engine combustion chamber conditions above 1000°C

- Corrosion-resistant stainless steel(15-5PH, 17-4PH) : for avionics system support, hydraulic pipeline, through the salt spray test 2000 hours

3. Custom forming process

- Provide the most large-scale forgings (300-700MN hydraulic press forming), the most precision pipe (ultra-thin wall hydraulic pipe), the most 3D printed powder (SLM solution for Nickel-based alloy)

Industry application and innovation trends

- Weight reduction and fuel efficiency : Airbus A350 adopts 50% composite material +20% titanium alloy structure, Shengxi supplies CT20 titanium alloy forgings, reducing fuel consumption by 12%

- Additive Manufacturing Applications : Equipped with laser cladding (LMD) Rene 41 powder for GE Aviation, reducing engine part delivery time by 60%

- Safety Upgrade : Developed aviation-grade Al-Li alloy (2099-T83), improved fuselage impact resistance and reduced weight by 18%, has passed FAA airworthiness certification

The latest industry data show that in 2024, global aviation material research and development investment increased by 23% year-on-year, of which COMAC C929 project supply chain demand for domestic high-end alloys surged. Shengxi assists customers to optimize the whole process cost from design to mass production through the AI selection system of the material database. At present, the products have been applied to key projects such as LEAP engine and Long March rocket fuel capsule , promoting the sustainable development of the aviation industry with material innovation.
