Zinc Castings Case Study

MES Zinc Castings Case Study

Design Benefits: The process of zinc die casting involves a time-proven technology. As a material, zinc is extremely fluid, rendering it very useful for die casting. Zinc also offers excellent strength (~32,000 psi) compared to conventional aluminum 380 and magnesium (~23,000 psi). Specific grades of zinc produce castings with yield strengths in excess of 57,000 psi. While standard zinc castings can offer Brinell hardness of 82 HB compared to 80 HB for aluminum and 63 HB for magnesium, there are grades of zinc that can produce alloys in the range of 120 HB resistance, an increase in hardness of approximately 50 percent. Depending on the grade used, zinc alloys offer high strength with a high degree of creep resistance. Process Benefits: Because zinc is the most fluid of all die casting alloys, zinc die castings can be made thinner than with other metal alloys. Their shapes can be more intricate […]
