Different Die Casting Alloys. Die casting is the method of manufacturing metal parts by pushing the melted alloys in the molds under high pressure. The high pressure is vital because it can diminish the air cavities that can form throughout the creation of the parts. There are two procedures that can be utilized in die casting: hot chamber and cold chamber process. They change in the time desirable to finish the cycle and also in the sort of alloys that can be utilize in the machines to make die cast parts. Alloys with low melting point can be manufactured in hot chamber and those with high melting point in the cold chamber.
The customary die casting alloys employed in die casting are aluminum, zinc, copper, magnesium, tin, and lead. They have diverse metallurgical properties so the treatment in these alloys relies on their nature.
Aluminum, copper, and zinc alloys are the standard die casting alloys utilized in die casting. Aluminum is not developed as pure aluminum because it is tends to hot cracks and shrinkage. So makers merge it with others such as silicon and copper. A use of aluminum parts relies on how greatly alloying element is alloyed with the aluminum. Engines utilize aluminum with high silicon content.
Copper is corrosion resistant and can diminish ductility so it usually alloyed with other metals. Copper parts are typically for plumbing and marine applications. Corrosion resistance is vital in these things.
Zinc has high melt fluidity so it can be utilized in precision parts such as connector housings, gears, and sprockets. It is more often than not alloyed with aluminum but in low amount only.
The other die casting alloys that can be utilized are magnesium, tin, and lead. Magnesium is the lightest alloy that can be die cast. Tin and lead, on the other hand, are high in thickness and can be employed in parts that are required to be corrosion resistant.
