Types of Die Cast Metals
Aluminum –
Aluminum is one of the most commonly used metals in die casting. It has excellent strength-to-weight ratio, making it ideal for lightweight components. Aluminum die castings are also highly corrosion resistant and can withstand high temperatures, making them suitable for use in harsh environments.
Some common applications of aluminum die castings include:
- Automotive parts, such as engine blocks, transmission housings, and suspension components
- Electronic components, such as heat sinks, enclosures, and brackets
- Consumer goods, such as kitchen appliances, power tools, and sporting equipment
Magnesium –
Magnesium is another lightweight metal commonly used in die casting. It has a high strength-to-weight ratio, making it an excellent choice for parts that require both strength and lightness. Magnesium die castings are also highly resistant to corrosion and can withstand high temperatures.
Some common applications of magnesium die castings include:
- Automotive parts, such as steering wheels, transmission cases, and engine blocks
- Electronic components, such as laptops, tablets, and smartphones
- Aerospace components, such as aircraft engine parts and structural components
Zinc –
Zinc is a versatile metal that can be easily die cast into complex shapes. It has excellent strength, durability, and dimensional stability, making it ideal for components that require high precision and accuracy. Zinc die castings are also highly corrosion resistant and can be finished with a variety of coatings and finishes.

NADCA: For Efficient Manufacturing, Look to Die Casting A concise outline of the specific facts regarding how die casting manufacturing efficiency contributes to ecological sustainability: All die casting metals can be recycled and reused with no loss in material properties, resulting in the vast majority of die castings made with post-consumer metals which, in addition, require far less energy to reprocess than virgin materials. In the production of non-ferrous metal castings, die casting is the most energy-efficient casting process, with reusable molds and very high production rates resulting in highly-efficient energy usage. The carbon footprint of the die casting industry is among the lowest among producers of net- or near-net shape products and component parts—far less than that of plastic injection moldings.
