LM4 Aluminium ingots
LM4 is a widely used general purpose alloy for most general engineering purposes. Both thick and thin casting sections can be formed from LM4 aluminium castings and it finds addition uses due to its castings pressure tightness. When heat treated relatively high static loading can be maintained. LM4 is used in both sand and die casting.
