Know about the Use of Alloys in Die Casting

In maximum cases, the need for post-production machining can be reduced or eliminated by die casting, raising the cost-efficiency of the process and shortening fabrication time. It can be difficult to die cast sturdier metals, such as certain grades of steel; there are many other types of well-suited for alloy die casting methods.

Usually from hardened steel die casting molds are constructed and in a die casting machine they are often the most expensive component. These molds can even handle a range of different alloy families with varying results, but on metals with low fusing temperatures die casting is generally most effective. Because of this reason, the common die casting alloys fall into a handful of categories based on their composition and material properties.

Zinc Alloys

In die-cast, zinc-based materials are relatively easy, and to the die molding process, they respond well. With multiple metals, these materials are comprised of and that too in specific ratios. The workpiece becomes more flexible with slightly higher proportions of tin, while increased copper levels improve rigidity.

In place of cast iron or brass Zinc die castings from alloy die casting suppliers are often used, but compared to their sturdier counterparts they tend to have lower tensile strength. As a result, in applications involving high mechanical loads, die-cast zinc products are generally not used. By alkaline substances or salt-water, zinc castings can be corroded, and are often plated to preserve their luster despite atmospheric conditions.

Aluminum Alloys

In automobile parts and gears, die-cast aluminum alloys are often found, and in the past, they have been used to create surgical instruments. Compared to most zinc-based materials they are quite stronger and lighter but tend to be more expensive to create. The alloy die casting manufacturer is very reliable.

The need for finishing treatments, such as plating can be reduced by using aluminum alloys, and the common grade is composed of 92 percent aluminum mixed with 8 percent copper. To improve its tensile strength magnesium may be added to this alloy, while to increase rigidity and provide a higher surface finish nickel can be included.
