DIN 1725-2 G-AlSi9Cu3 Alloy (Grade 3.2163 F) – Ideal for Complex Castings
G-AlSi9Cu3 is universally used alloy with very good casting characteristics. It is characterised by less inclination to breaking in and to cavities and is mostly not hardened. The alloy is suitable for difficult shapes, thin-walled, pressure tight, oscillating loaded, impact loaded cast parts. Application: Complicated machine and engine components for vehicle industry, electrical engineering, mining industry etc., cranking, housing, electric motor parts, bearing plate and supports, cylinder heads, linings etc.
