This page explains how Aluminum Die Casting is classified within Basic Metal Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
Aluminum die casting is a manufacturing process that produces complex, high-precision metal parts by injecting molten aluminum alloy into a steel mold under high pressure.

Common alloy grades include A380, A383, A360, A413, and ADC12 (Japanese equivalent). These grades differ in composition, affecting strength, corrosion resistance, and castability. Selection depends on the application's requirements.
Typical dimensional tolerances range from ±0.05 to ±0.13 mm, depending on part size and feature complexity, as per ISO 8062-3. Actual tolerances must be confirmed with the manufacturer for specific parts.
As-cast surface roughness (Ra) typically ranges from 0.8 to 3.2 µm, per ISO 1302. This can be improved with polishing or coating if required.
Relevant standards include ASTM B85, ISO 3522, EN 1706, GB/T 15115, and SAE J468. These standards cover material specifications, testing methods, and quality assurance. Always verify compliance with the supplier.
