Aluminum sand castings

The most versatile method for producing aluminum products is sand casting. The process starts with a pattern that is a replica of the finished casting. Virtually any pattern can be pressed into a fine sand mixture to form the mold into which the aluminum is poured. The pattern is slightly larger than the part to be made, to allow for aluminum shrinkage during solidification and cooling. As compared to die and permanent mold casting, sand casting is slow process but usually more economical for small quantities, intricate designs or when a very large casting is required.


535 Almag/Almag 35 Aluminum Sand Castings

Aluminum alloy 535.0, also called almag 35, is an aluminum magnesium alloy that does not require heat treatment to reach full properties. It has excellent corrosion resistance and machining characteristics. Milling and turning speeds are 4X faster than alloy 319.0, and 16 to 18 times faster than gray iron or malleable iron.

The anodizing rating is excellent and the color is satin white after anodizing.

The polishing rating is also excellent and the castings can be buffed to a silvery white color.

The weldability rating is poor and it also is not recommended for leak tight or pressure type applications.

Typically used for parts where dimensional stability and shock resistance is important. It is also used for marine hardware, ornamental fittings and castings where lighter weight and high strength is a prime consideration.  Almag 35 is 10% lighter than average cast aluminum alloys, 64% lighter than gray iron and 69% lighter than bronze.
