Custom Aluminum Precision Parts

Aluminum alloys are alloys in which aluminum is the predominant metal. Aluminum becomes an alloy when it is combined with other elements such as iron, copper, magnesium, tin, silicon, and zinc. Aluminum alloys are available in various shapes and grades.

At Deeco Metals, we offer aluminum casting services to customers in a range of industries. Whether you need a part that’s functional, decorative or both, we can help. We have experience working with aluminum alloys of all types.

Aluminum Die Castings for Top-Shelf Parts

Aluminum casting is an effective way to produce precision parts. When selecting an alloy for aluminum casting, you’ll need to consider the following factors:

  • Casting design: The aluminum alloy you select will depend on how simple or complex your design is.
  • Preferred casting process: It’s important to select the right alloy for the aluminum casting process that you intend to use. Our team can help you make the right choice.
  • Availability: If your desired aluminum alloy is in short supply, we can help you find an alloy with similar properties.
  • Cost: The alloy you choose will greatly influence the cost of your project.
