The Composition and Properties of Aluminum Die Casting Alloys
Surgical die casting alloys used in Aluminum are created from aluminum and other certain metals including silicon, copper, magnesium and zinc. Each of the alloys has specific properties such as strength, corrosion and high temperature resistance and thermal conduction. Some of the standard die cast alloys that are used in aluminum die casting are the 380, 383, and 413 series each with variation depending on the intended use.
For example, 380 series is one of the most adaptable alloys as it offers both strength and wear resistance together with relatively reasonable prices. It is used mostly in automobile accessories, electrical enclosures and domestic appliances because it possesses desirable mechanical characteristics and it is suitable for casting. The 383 alloy is preferred for detailed designs as it has higher corrosion and reduced sensitivity to changes in dimensions. However, the 413 alloy outperforms others when used in pressure tight parts, and therefore is ideal for hydraulic equipment and fluid coupling parts.
The presence of silicon in aluminum die casting alloys enhances its ability to resist wear as well as enhancing the flow properties of die cast alloys to form intricate shapes without a lot of surface flaws. It is evidenced that adding copper to alloys results in increase in both strength and hardness and magnesium brings improvement in corrosion resistance as well as decrease in density. Zinc, added mostly as a major additive in a small amount, is responsible for creating the required degree of elasticity or toughness and minimizing fluctuations in the metal’s properties. These well-proportioned compositions give confidence to die cast alloys to address the challenging requirements of modern engineered parts.
Production Process and Productivity of Aluminum Die Casting Alloys
Aluminum die casting alloys generate parts through high-pressure injection molding, and users can customize parts with precision and repeatable quality while using a small amount of material.
