With die casting<\/a> being an efficient way to manufacture complex components, it is important to understand the benefits of commonly used metals for die cast parts. The best die casting methods and metals will be largely determined by your component\u2019s complexity and functionality.<\/p>\n\n\n\n

Aluminum, zinc, and magnesium are common metal materials used for die cast metal parts. While each metal type offers corrosion resistance, the levels of rust protection vary. Less common die cast metal includes brass, copper, or other specialty alloy materials.<\/p>\n\n\n\n

Aluminum Die Casting<\/h2>\n\n\n\n

As a well-known metal for its corrosion-resistance, aluminum<\/a> is a popular die cast metal option. Aluminum\u2019s mechanical properties of lightweight with high strength-to-weight ratio make it an ideal choice for a wide range of components and parts.  Aluminum can also withstand high heat temperatures making it a versatile choice for different die casting methods.<\/p>\n\n\n\n

With little to no iron in its chemical composition, aluminum is a rust-proof alloy. While aluminum does not rust, it can corrode depending on environmental factors.<\/p>\n\n\n\n

Zinc Die Casting<\/h2>\n\n\n\n

Ideal for automotive or electoral applications, zinc alloys provide excellent corrosion-resistance. Due to its smooth surface finish, zinc works best for applications that will not be subjected to high temperatures.<\/p>\n\n\n\n

Marine and atmospheric environments with salt will eventually corrode zinc die cast components. While zinc can corrode in harsh atmospheric environments, it is well suited for most die cast components including automotive die cast parts.<\/p>\n\n\n\n

Magnesium Die Casting<\/h2>\n\n\n\n

While magnesium<\/a> provides benefits including lightweight composition and recyclability, it is not inherently corrosion-resistant like aluminum or zinc. Sprays or coatings for magnesium die cast components can provide the galvanic corrosion protection needed for most components.<\/p>\n\n\n\n

Choosing the Best Alloy for Your Die Cast Project<\/h2>\n\n\n\n

Aluminum, zinc, and magnesium all offer different levels of corrosion resistance. However, the best alloy for your die casting project depends on other factors for consideration.<\/p>\n\n\n\n
