A356.0 Primary, 356.0 Secondary


This Aluminum and Silicon alloy must be heat treated to develop full strength, hardness and allow ease in machining. Once heat treated it has excellent pressure tightness, very good resistance to corrosion and good machinability. Major uses include water-cooled cylinder heads, transmission cases, axle housings, wheels, bridge rail parts, pump bodies, marine and tool parts, hose fittings and other liquid pressure items.
