& Comparison Tool
Look up chemical composition, mechanical, thermal, and electrical properties for the HPDC and GDC aluminium alloys SAPL casts, plus other widely used global reference alloys (JIS H5302, ASTM B85, BS 1490, BS EN 1706) — or compare two alloys side by side to decide which fits your component.

SAPL Note
SAPL's default HPDC alloy — run across all five HPDC machines (180T–450T). Not recommended for T6 heat treatment due to as-cast porosity.
Values shown are typical reference figures compiled from standard specifications (JIS H5302, ASTM B85, BS 1490, BS EN 1706) and SAPL production experience. Actual properties vary with section thickness, process control, and heat treatment. For application-critical specifications, request a material test certificate with your quotation.
