At NovaCast, a large proportion of our castings are produced using Aluminium alloy. The formation of Aluminium Oxide and the presence of non-metallic inclusions, collectively known as dross, is an inherent part of the casting process and one that must be managed to achieve the highest quality castings. For many years, part of the foundryman’s … Read more

ALUMINIUM CASTING ALLOY LM6M
(BS 1490:1988 LM6)
Aluminium Casting Alloy LM6M has a high resistance to corrosion and excellent castability. It finds uses in numerous places due to these properties such as marine, manifolds, motor casings, cast doors, pumping applications. It is also especially suitable where castings need to be welded together. The ductility of LM6 castings means they can be easily rectified and modified into shape. It is equally adaptable for both sand and permanent mould casting and for die castings.
LM6 aluminium castings have excellent resistance to corrosion in marine environments, possess excellent ductility, but is of medium strength and is not heat treated. Its strength falls off rapidly at high temperatures. Its elastic limit is low and it is fairly difficult to machine.
