Key Material: ADC12 Aluminum Alloy for Automotive Die Casting
The choice of material is critical for automotive die casting parts, and ADC12 aluminum alloy is the most widely used material in auto die casting. As an Al-Si-Cu series die-casting aluminum alloy, it offers excellent comprehensive performance that perfectly matches the needs of the automotive industry.
Core Composition of ADC12 Aluminum Alloy
The main chemical composition (mass fraction) of ADC12 is: Si: 9.6-12.0%, Cu: 1.5-3.5%, Mg: ≤0.3%, Zn: ≤1.0%, Fe: <1.3%, and Al as the balance. This composition gives ADC12 outstanding castability and mechanical properties, making it ideal for auto parts.
Why ADC12 is the Preferred Material for Automotive Die Casting Parts
- Excellent Castability: ADC12 has good fluidity and filling performance, ensuring molten metal fills complex mold cavities without defects like shrinkage or porosity.
- High Mechanical Strength: It offers high hardness and tensile strength, making auto parts durable against vehicle vibration, impact and high temperature.
- Lightweight Advantage: About 1/3 the weight of steel, effectively reduce vehicle weight, improve fuel efficiency and extend NEV battery life.
- Good Machinability: Easy for drilling, tapping and polishing, cutting down auto part production time and cost.
- Cost-Effectiveness: Affordable raw material cost, perfect for large-scale automotive parts mass production.
