Aluminum vs Zinc Die Castings
Aluminum is the most commonly cast non-ferrous metal in the world because it’s very cost effective. Its light-weight yet can withstand the highest operating temperatures of all the die cast alloys. It’s non magnetic, has good corrosion resistance and is also an excellent electrical conductor.
- High strength and dimensional stability for complex shapes
- Good corrosion resistance; high electrical and thermal conductivity
- Retains strength at high temperatures
- Little or no machining is required after an aluminum part is die cast, because the process provides very close tolerances
Zinc casting alloys are strong, durable and cost effective engineering materials. Their mechanical properties compete with and often exceed those of cast aluminum, magnesium, bronze, plastics and most cast irons.
- Wide variety of finishes
- 8-10 x greater tool life
- Exceptional fluidity
- Faster cycle times
- Good thermal conductivity
