Die Cast Metals, What Type Of Metal Should?

Die Cast Metals. The alloys you will typically choose from when it comes to die casting are aluminum, magnesium and zinc. There are other metal alloys you can use for die casting as well, like copper, brass, tin and lead, though these alloys are much less-common, specialty materials in the die casting industry. Since we’re working with alloys, or elements in a mixture, you will find metal die cast parts that incorporate several of these metals. Each alloy has different properties and different advantages and disadvantages that make them appropriate for different kinds of applications.

We manufacture miniature to large precision components in a broad range of zinc, aluminum, and magnesium alloys, using hot chamber and cold chamber die cast technologies, along with our proprietary multi-slide and standard tooling systems.
Each of the alloys have unique physical characteristics to match your specific application. Our experts will help you pick the ideal material to manufacture your precision component.

Aluminum Die Casting Metals:

Light weight and able to withstand the highest operating temperatures of all die cast alloys. Our proprietary Thin Wall Aluminum Technology has made it possible to build smaller and lighter products at lower component costs.

Aluminum Alloy Characteristics

  • High operating temperatures
  • Outstanding corrosion resistance
  • Lightweight
  • Very good strength and hardness
  • Good stiffness and strength-to-weight ratio
  • Excellent EMI and RFI shielding properties
  • Excellent thermal conductivity
  • High electrical conductivity
  • Good finishing characteristics
  • Full recyclability

Zinc Casting Metals:

High strength and exceptional hardness make zinc the ideal alternative to machined, pressed, stamped and fabricated components.

Zinc has a low melting point, which provides for longer mold life than aluminum die casting offers. Like aluminum, zinc has great corrosion resistance and high thermal conductivity. It’s quite durable, strong and hard and offers a great deal of dimensional stability.

Zinc alloy characteristics

  • High strength and hardness
  • Excellent electrical conductivity
  • High thermal conductivity
  • Low cost raw material
  • High dimensional accuracy and stability
  • Excellent thin wall capability
  • Ability to cold form, which eases joining
  • High quality finishing characteristics
  • Outstanding corrosion resistance
  • Full recyclability

Magnesium Casting Metals:

Strong, rigid, fully recyclable yet incredibly light with superior EMI/RFI shielding properties. Magnesium is the ideal die cast material for applications where weight saving is a priority.

Magnesium is a great choice for die casting when you need very light parts. Magnesium is extremely lightweight, with a high strength to weight ratio, low density, good corrosion resistance and good electrical and thermal conductivity. On the other hand, it’s more difficult to die cast due to its handling requirements, and it’s considered a “specialty” alloy in the die casting industry.

Magnesium alloy characteristics

  • High conductivity; electrical, and thermal
  • Withstands high operating temperatures
  • High dimensional accuracy and stability
  • Exceptional thin wall capability
  • Good environmental corrosion resistance
  • Good finishing characteristics
  • Full recyclability

Choosing Your Die Cast Metal

As you can see, different applications are better suited for different metals, and the metal that should predominate in your die cast parts is very specific to your product and your industry.

If the ability to withstand high temperatures is your highest priority, you will want a mostly aluminum alloy in your die cast part, although it is crucial to note that aluminum can only be die cast with a cold chamber machine. Other alloys, like zinc or magnesium, can work with hot or cold chamber machines. This distinction is important in the selection of a die cast vendor, as you’ll need to consider their available equipment.

If a lightweight part is your highest priority, you will usually want to go with magnesium, which is extremely light.

If ease of casting, economy and a great-looking final product are your top priorities, you may want to look more into zinc alloys, which cast very simply, still have good strength, hardness and dimensional stability and are quite easy on your dies, giving them a longer life than aluminum alloys have.

If corrosion resistance is your number-one requirement — for example, your parts are used in the food service industry — consider stainless steel and nickel . For high electrical and thermal conductivity, strength and wear-resistance, consider brass which is another special alloy.
