About LM4 Aluminum Alloy Ingot

LM4 is a British Standard (BS1490) aluminium casting alloy (Al-Si5Cu3), widely used in sand and die casting for engineering applications due to its versatility, machinability, and strength after heat treatment.

Chemical Composition

LM4 alloy primarily consists of aluminium as the base, with silicon and copper as major alloying elements, and limits on impurities like iron and zinc.

The standard composition per BS1490:1988 is detailed below:

Element	Composition (%)
Silicon (Si)	4.0 - 6.0
Iron (Fe)	0.8 max
Copper (Cu)	2.0 - 4.0
Manganese (Mn)	0.2 - 0.6
Magnesium (Mg)	0.2 max
Zinc (Zn)	0.5 max
Lead (Pb)	0.1 max
Tin (Sn)	0.1 max
Nickel (Ni)	0.3 max
Titanium (Ti)	0.2 max
Others (each/total)	0.05 / 0.15
Aluminium (Al)	Remainder

This composition ensures good castability for thick and thin sections, pressure tightness, and enhanced properties post-heat treatment.

Versatile Applications

LM4 Aluminum Alloy Ingots are widely used in remelting procedures for the production of automotive and defense components. Their consistent composition and high purity make them an excellent choice where reliability and strength are paramount.

Superior Manufacturing Standards

Produced using advanced ingot techniques by leading Indian manufacturers, the LM4 Alloy Ingots deliver precise chemical proportions and consistent quality. Their standardization ensures ease of remelting and excellent casting properties.
