Precision-engineered engine brackets (Aluminum A380-T6 alloy) deliver optimal strength-to-weight ratios (tensile strength ≥310 MPa, weight reduction up to 40% vs. steel) for modern powertrain systems. Utilizing vacuum-assisted high-pressure die casting (1600T+ machines), these components achieve ±0.05mm dimensional stability and Ra ≤1.6µm surface finish, validated through CMM and X-ray inspections. Integrated heat dissipation properties (thermal conductivity ≥100 W/m·K) ensure reliability in hybrid/electric vehicle thermal management systems, while anodized coatings (≥20µm thickness) withstand 1,000+ hours salt spray corrosion.
