Cast Aluminum A380 & ADC12 Die Casting Alloys

Optimal Fluidity, Pressure Tightness, and Dimensional Stability for High-Volume Castings.

A380 (US standard) and ADC12 (Japanese JIS standard) are the premier silicon-copper-aluminum alloys for high-pressure die casting. Featuring excellent liquid melt fluidity, hot tear resistance, and high stiffness, these alloys excel in thin-walled automotive transmission housings, LED lighting heat-sink bodies, and electric tool enclosures produced in quantities from 500 to 500,000 pieces.

Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for Cast Aluminum A380 & ADC12 Die Casting Alloys.

What is the main difference between A380 and ADC12? +
ADC12 has higher silicon content (up to 12%), giving it slightly better fluidity for very intricate or thin-walled parts, while A380 is the North American standard equivalent.
What minimum wall thickness can you die cast in A380? +
Standard minimum wall thickness is 1.5mm to 2.0mm. In localized areas with optimal gate placement, wall thicknesses of 1.2mm can be achieved.
Can A380 castings be anodized? +
High silicon and copper contents cause standard clear anodizing to turn a dark mottled grey. For cosmetic finishes, we recommend shot blasting, e-coating, or powder coating.
What is the typical tooling lifespan for aluminum die cast molds? +
Made from premium H13 or DIEVAR hot-work tool steel, our die casting molds reliably produce 80,000 to 120,000 shots before cavity replacement is required.
