May 22, 2017 Aluminum alloys that have been proven to perform well for permanent-mold casting include 319, 356, A356, 413, and 535. When deciding which one is right for your particular application, a number of questions must be considered first. For example, the type of resin that is being used will affect the choice of aluminum alloy.
Permanent mold casting is a gravity induced method of creating custom metal products and components that are as small as a few ounces or as large as 100-plus pounds. Permanent mold castings have less shrinkage, lower gas porosity and a denser microstructure than their sand and die casted counterparts.

The rapid solidication rate associated with the die casting process makes die casting alloys somewhat superior to wrought and gravity cast alloys of similar chemical composition. Alloy A380 has better than average machining characteristics.
Permanent mold casting, also known as gravity die casting, is similar to die casting and uses reusable steel molds to produce molded components. To create a part, molten aluminum is poured into the steel mold via gravity or filled via low pressure. After the aluminum casting has cooled, the part is removed from the mold and finished.
Permanent mold casting molds are preheated, and thermal temperatures are maintained as molten aluminum and magnesium alloys are poured over patterns to shape the product. After setting the mold, pull the mold out to expose the smooth mold cavity need to be processed. In the gravity permanent casting process, the metal flows by gravity (either ...
