Premium Aluminum Alloys We Offer

We help you choose the right alloy for strength, weight, thermal conductivity or corrosion resistance. Popular grades: ADC12 (best castability), A380 (high strength), A356-T6 (excellent toughness & airtightness).
| Alloy | Key Properties | Common Applications |
|---|---|---|
| ADC12 | Excellent fluidity, thermal conductivity ≥180 W/m·K | Heatsinks, auto brackets |
| A380 | Tensile strength ≥320 MPa | Aerospace brackets, motorcycle wheels |
| A356-T6 | High elongation ≥8%, pressure tight | EV battery housings, valve bodies |
Our Precision Die Casting Process
