Casting		 Notes
A319 X X X Used to simulate the heat transfer rates of die-cast A380
A355 X X X Rarely used, but is still supported
A356 X X X Most common gravity cast alloy of aluminum. With a T6 temper, the mechanical properties are used to simulate die-cast A380
A357 X X X Stronger than A356. Best gravity cast aluminum for parts where strength is a concern
A380 X X X Gravity cast A380 is used when parts will be submitted for independent inspection prior to die-casting
AZ91D X X X Most common gravity cast magnesium alloy. Lightweight.
AM60 X X   Magnesium alloy still used in many applications
Stainless Steel X   X Many alloys of stainless steel are available
Zinc X X X Nearly as strong as steel, zinc is an excellent choice when weight is not a design concern
Brass and Bronze X   X Many alloys of brass and bronze are available
Iron X   X Grey iron and ductile iron are cast for a variety of uses.
