Alloy AK9M2
Designation
Description
Alloy AK9M2 used: for the manufacture of ingots and shaped castings in a variety of ways of casting (chill casting, injection molding).
Note
Aluminum foundry alloy of the system Al-Si-Cu.
Standards
Chemical composition
Al is the base.
According to GOST 1583-93, the iron content is indicated for casting in chill molds. Casting in sand molds and waxed models from this alloy is usually not made. The iron content for injection molding should be ≤ 1.20%. The amount of allowable impurities should be for die casting ≤ 2.60%, die casting ≤ 2.80%. The total content of lead and tin should be ≤ 0.15%.
