Aluminium Alloy - LM5

The LM5 alloy is used where very high resistance to corrosion from sea water or marine atmospheres is required, for equipment used for the manufacture of foodstuffs, cooking utensils and chemical plant, and for castings required to exhibit and maintain a surface of high polish. Applications include, for example, door furniture, car fittings and trim, and similar castings where a colourless anodic film is required.

It is mainly used for sand castings and, to a lesser extent, for permanent mould castings but die castings of a relatively simple shape have been made.
