AlSi7Mg

Aluminium alloy powder

The lightweight aluminium alloy with high strength, good thermal and electrical conductivity and corrosion resistance. The presence of silicon makes the alloy stronger and harder compared to pure aluminium

The powder is manufactured by Inert Gas Atomization (IGA) delivering high spherical morphology of particles. Ultrafine powder has low density and uniform particle size.

Other codes: DIN 3.2371, USA A03560, ISO AlSi7Mg, JIS AC4C, GOST AK7
