Aluminum Die Casting vs. Zinc Die Casting: The Benefits and Uses of Each
BENEFITS AND USES OF ZINC DIE CASTING
Zinc alloys are best known for their high ductility, impact strength, and their ability to be easily plated or finished. They also have a lower melting point than aluminum, which can assist in promoting longer die life. Due to these benefits, less material is often needed than would be if working with other alloys, leading customers to save both time and money on their project.
While often used in industrial spaces and building, one of the most common applications of zinc alloys is to produce automobile parts. Some automobile parts zinc is typically used for include (but are not limited to:
- Engine and other “under-the-hood” components
- Power steering systems
- Brake parts and systems
- Air-conditioning components and systems
- Fuel systems
- Complex net-shaped housings
- Electronic devices
Interestingly enough, due to the number of part production it requires, the automotive industry was at least partially responsible for the die casting process to begin with.
BENEFITS & USES OF ALUMINUM DIE CASTING
On the other hand, aluminum die casting alloys are lightweight and possess high dimensional stability that works particularly well for complex part geometries (including thin walls). Aluminum alloys have strong corrosion resistance and mechanical properties as well as high thermal and electrical conductivity, making them a great alloy for die casting. It is common to see aluminum alloys used in a wide variety of applications, including:
- Electronics
- Communications equipment
- Gear cases
- Lawnmower housings
- Hand and power tools
- Some automotive components
