Zinc

Zinc alloy characteristics:

• High strength and hardness
• Excellent electrical conductivity
• High thermal conductivity
• Low cost raw material
• High dimensional accuracy and stability
• Excellent thin wall capability
• Ability to cold form, which eases joining
• High quality finishing characteristics
• Outstanding corrosion resistance
• Full recyclability

Zinc’s high strength and hardness lends itself to many solutions and it’s the ideal alternative to machined, pressed, stamped, and fabricated components.

Applications for Zinc:

• Complex net-shaped zinc housings, with precise thin walls offer excellent electrical performance and shielding properties
• Our proprietary multi-slide die casting process and superior thin-wall capabilities make us the foremost supplier of zinc components for broad range of consumer electronic devices
• The castability of zinc, its wear resistance, and structural integrity make it perfect for the creation of the multi-faceted, highly complex shapes used in automotive safety and electronics industry
