Alloy A356.0 has greater elongation, higher strength and considerably higher ductility than 356.0. It has these improved mechanical properties because impurities are lower in A356.0 than in 356.0. Typical applications are airframe castings, machine parts, truck chassis parts, aircraft and missile components, and structural parts requiring high strength.
All casting characteristics are excellent for this alloy.
Alloy A356.0 has good machinability. Abrasiveness can be overcome and high tool wear can be minimized by using sharp, carbide-tipped (or better) tools with high rakes and clearances. Moderate to fast speeds are recommended.
Electroplated finishes are very good. Chemical conversion coatings give very good protection, but anodized appearance is only fair. Mechanical finishes on A356.0 are good.
All common welding methods are excellent for joining this alloy. Brazing is not performed.
This alloy has very good resistance to most common forms of corrosion.
