What are the differences between Aluminum and Zinc Die Casting?

Differences Between Aluminum Die Casting and Zinc Die Casting Aluminum and Zinc are two of the most popular alloys for die casting. Is Aluminum or Zinc the better alloy? It depends upon how you look at it.

Zinc is easier to cast than aluminum. Of all the popular die casting alloys, zinc has the lowest minimum section thickness at 0.63 mm. Aluminum, on the other hand, has a minimum section thickness of 0.89 mm. Therefore, Zinc die casting is the most production-friendly between the two alloys.

Aluminum is less heavy than zinc. The minimum draft of aluminum needed for die casting is 1:100 while zinc has it at 1:200. Zinc’s thickness is at 6.6 gms/cubic cm while aluminum’s is 2.74 gms/cubic cm. Because of the thickness, aluminum die casting can produce more castings per ton of metal than zinc die casting, in spite of the latter being the easier to cast.

Zinc alloy is tougher than aluminum and any other types, especially in terms of impact strength. Due to zinc die casting being more pressure tight than aluminum die casting, zinc is restored in terms of waterproofing capability. Products made from aluminum-based alloys are most probable to leak when exposed to waterproofing tests and actual conditions.

Zinc melts easier than aluminum. Aluminum melts at 1,221 degrees Fahrenheit while zinc melts at 787.2 degrees Fahrenheit. In terms of heat resistance, aluminum will appear to be better than zinc. However, in terms of cost-effectiveness, this data only means that because zinc melts effortlessly than aluminum, it can be cast easier using a less expensive method called “Hot Chamber”. Aluminum die casting, on the other hand, uses a more costly and slower method of casting called “Cold Chamber”.

Overall, both materials have their individual advantages and disadvantages. This is the beauty of having more than one option for die casting. The ultimate beneficiary of this diversity is not unavoidably the industries elaborate in this procedure, but the customer.
