Aluminium Alloy - LM27

LM27 is a very versatile alloy and, with its excellent castability, is suitable for most general purpose castings where moderate mechanical properties are desirable, such as general engineering components, domestic and office equipment, household fittings, electrical tools and switch gear, automobile engine and transmission components.

It is equally suitable for sand and gravity die castings of thick or thin sections, and for castings required to be pressure tight. In short, it can be used with the advantage of slightly superior castability for the all the kinds of application for which LM4 is used and may be expected, in time, to supersede the older alloy.
