About LM9 Aluminium Alloy Ingots
LM9 is a British Standard (BS 1490:1988) aluminium-silicon casting alloy (Al-Si12Mg), designed for sand and die casting with excellent fluidity, pressure tightness, and corrosion resistance in as-cast (M), precipitation-treated (TE), or fully heat-treated (TF) conditions.
Chemical Composition
Per BS1490 standards, LM9 features high silicon content for castability and magnesium for strength enhancement, with tight limits on impurities
This composition supports applications in automotive parts, valves, and pumps, offering good machinability and heat resistance up to 150C.
