Material
Zinc
Zinc is a versatile metal widely used in die casting, corrosion protection, and precision industrial components. Zinc alloys offer excellent castability, dimensional repeatability, and the ability to reproduce detailed features, making them suitable for connectors, housings, fittings, hardware, and high-volume manufactured parts.
Material overview
Zinc and zinc-based alloys are commonly selected for pressure die casting and corrosion protection applications.
Zinc alloys generally offer relatively low melting temperatures, good fluidity, and favorable dimensional characteristics for complex cast components.
Common grades include:
- Zamak 3: A widely used zinc die casting alloy offering a balance of mechanical properties, dimensional stability, and finishing characteristics.
- Zamak 5: Provides higher strength than Zamak 3 in certain applications.
- ZA-8: A zinc-aluminum alloy used where improved strength and wear characteristics are required.
- Zamak 2: A higher-strength zinc alloy suitable for selected mechanically demanding castings.
Manufacturing methods include die casting, CNC machining, drilling, tapping, and secondary finishing.
Zinc die casting is particularly suitable for detailed geometries, thin sections, integrated fastening features, and repeatable medium- to high-volume production.
Applications include electrical housings, industrial fittings, locks, mechanical hardware, automotive components, and decorative products.
Finishing options include electroplating, painting, powder coating where process conditions permit, and decorative surface treatments.
Buyers should specify the alloy, 3D model, dimensional tolerances, annual production quantity, surface finish, and required mechanical properties.
Inspection may include dimensional verification, surface assessment, material composition testing, and functional testing.
