Material Description

Material Number Material Number (single) Standard Scope Standard Status Country Successor VDA 231-106 classification
3.2582 (DIN 1725-2 : 1986-02) 3.2582 DIN 1725-2 : 1986-02 DIN 1725-2 : 1986-02 replaced by DIN EN 1676 : 1997-02 and DIN EN 1706 : 1998-06 Replaced Germany EN AC-Al Si12(Fe)(a) 2.1 1)
1) Remark: GD-AlSi12 is a not hardenable eutectic alloy with excellent filling casting ability and high hot cracking resistance with high chemical resistance. It is especially applicable for higher loaded corrosion resistant and fatigue-strength cast pieces. Application: parts of machines, impact and fatiguing loaded parts, cylinder head, engine, crank and pump cases, impeller, rip bodys, thin-walled cases, difficult blocks and plates
