LM6 Aluminum Alloy, having high resistance to corrosion and excellent castability, is most suitable for marine ‘on deck’ castings, watercooled manifolds and jackets, motor car and road transport fittings, thin section and intricate castings such as motor housings, meter cases and switch boxes, for very large castings, e.g., cast doors and panels where ease of casting is essential, for chemical and dye industry castings, e.g., pump parts, for paint industry and food and domestic castings. It is especially suitable for castings that are to be welded.
It is equally adaptable for sand and permanent mould castings and for die castings.
This alloy has excellent resistance to corrosion in marine environments, possesses 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 there is difficulty with machining.
