Description

Alloy Amg5mc used: for the manufacture of ingots and shaped castings by various casting methods (sand casting, investment casting, gravity die casting, pressure casting); casting parts of valves and actuators to it; details of average load produced by all means pouring and working at the corrosion impact and alternating loads.

Note

Aluminum foundry alloy system Al-Mg.
Corrosion resistant thermally neurocinema alloy of medium strength having a satisfactory castability.
