3 Important Differences Between Aluminum and Zinc

Aluminum die casting supplier

Many businesses are selling quality products with the help of a die casting supplier. Statistics show that castings are used in 90% of all products that are manufactured. Many companies choose either aluminum or zinc die casting for upcoming projects. Both zinc and aluminum work extremely well for many types of products. It’s understandable to wonder about the differences between aluminum and zinc. Here are three differences between the zinc and aluminum die casting processes.

  1. Conductivity

    Many business owners require that products are conductive. Aluminum die casting is often preferred when you’re needing electrical conductivity. You’ll find that aluminum is able to withhold the highest temperatures of all die casting materials. Die cast aluminum is often utilized in the creation of incredibly durable products. If your products require a high amount of thermal conductivity, it’s best to choose zinc die casting.
  2. Magnetism

    It’s true that both aluminum and zinc are not considered to be magnetic. However, zinc can attain magnetic properties when exposed to a strong magnetic field. If it is imperative that your product not be magnetic whatsoever, you’ll want to choose aluminum over zinc. Statistics show that aluminum makes up for about 80% of all parts that are die cast.
  3. Melting Temperature

    Zinc is often chosen as a die casting material due to how easy it is to cast. The typical melting range of zinc is anywhere from 380-390 degrees Celsius. Aluminum has a melting point of about 660 Celsius, almost twice that of zinc.

In closing, there are several important difference between aluminum and zinc die casting. If you’re seeking electrical conductivity, it’s best to choose aluminum die casting. Zinc is an excellent conductor of heat. Both zinc and aluminum are not magnetic materials. However, zinc can take on magnetic properties when surrounded by a large field of magnetism. It’s important to understand that melting points of both zinc and aluminum. Zinc has a far lower melting point than aluminum, making it preferable under extreme deadlines. If you’re still unsure about which material to choose for your next job, it’s best to contact a die casting supplier. These suppliers will be able to help you find the perfect die casting material.
