Our GLL Chassis Parts has achieved a double breakthrough in strength and corrosion resistance through the exclusive aluminum alloy material formula developed. The precisely blended trace elements such as copper (Cu), magnesium (Mg), and manganese (Mn) in its formula make the material tensile strength reach more than 280MPa, the yield strength exceed 220MPa, and the elongation remain above 7%. This patented formula not only gives the parts excellent mechanical properties, but also forms a dense oxide film through surface anodizing treatment, which increases its corrosion resistance by 40% in the atmosphere and humid environment. Compared with conventional steel chassis, GLL aluminum parts reduce weight by 50% without sacrificing structural strength, truly achieving a balance between lightweight and reliability.
Our GLL aluminum die-cast chassis components surpass traditional materials in key performance indicators:
Heat dissipation performance: thermal conductivity 235W/(m·℃), 3 times higher than steel, significantly reducing motor operating temperature;
Vibration damping: NVH (noise, vibration, harshness) performance is optimized by 25% through material microstructure regulation;
Fatigue life: no cracks after 2 million cycle tests, meeting automotive-grade reliability standards;
Weldability: supports seamless welding after T6 heat treatment, providing process guarantee for integrated design.
Our GLL adopts the world's leading semi-solid die-casting technology to control the molten aluminum liquid in the solid-liquid two-phase region for molding. This technology significantly improves the quality of components through the following three major innovations:
Microstructure optimization: The structure of the spherical solid phase wrapped by the liquid phase reduces the internal porosity of the casting by 80%, and the density is close to the theoretical limit;
Hot crack control: The solidification shrinkage rate is reduced by 40%, effectively avoiding the hot crack problem of traditional die casting;
Molding accuracy: With high-precision mold design and parameter control, the component size tolerance can be controlled within ±0.1mm, meeting the manufacturing needs of complex geometric structures.
Our GLL can customize the following chassis components according to customer drawings and technical requirements:Suspension Brackets, Control Arms, Steering Knuckle Housings,Motorcycle Swingarms and Subframe Components.
