Non-Ferrous Sand, Die and Permanent Mold Castings
Non-ferrous alloys do not contain iron in appreciable amounts. Common materials are aluminum, brass, copper and titanium. Non-ferrous castings can be made using sand casting process, investment process, or metal mold process including low pressure permanent mold process and high pressure die casting process (HDC). HDC is typically used to produce small to medium size and large volume products.
Most popular non-ferrous metals casted for industrial applications are aluminum alloys, copper based (bronze and brass) alloys, Zinc and magnesium alloys, etc.
Non-ferrous metals are typically used for structural applications because of desirable properties such as low density, higher strength to density ratio, higher conductivity, non-magnetic property or resistance to corrosion, etc.
Aluminum alloys are commonly used in automotive industry for engines, cylinder heads, manifolds, etc. They are also used in food packaging, cooking equipment, frameworks for electronics and appliances, window frames, doors, internal combustion engines. Copper alloy products can be used as fluid connectors, valves, heat exchangers, and bearings for components for crushers, loaders, shovels, and earthmoving equipment.
