Zinc Alloys
High-Performance Die-Casting Solutions
Zinc alloy is a mixture of zinc with other metals, such as aluminum, copper, and magnesium, that enhances properties like strength, corrosion resistance, and ductility. Common applications include die casting for parts in the automotive, electrical, and hardware industries, as well as coatings (galvanizing), and the manufacturing of various consumer goods like jewelry and zippers.
Product Overview
What is Zinc Alloys?
Zinc alloys are widely used engineering materials known for their high strength, durability, and excellent castability. Primarily composed of zinc mixed with other metals like aluminum, copper, and magnesium, these alloys offer enhanced properties compared to pure zinc, such as superior corrosion resistance and dimensional stability. They are the fourth most used metal globally, after iron, aluminum, and copper.
- High Impact Strength: Zinc alloys have high impact strength, making components durable and resistant to degradation from repeated use.
- Corrosion Resistance: They form a natural, protective oxide layer on their surface that acts as a barrier against moisture and oxidation, slowing the corrosion process, especially when alloyed with aluminum and magnesium. This makes them ideal for marine and outdoor applications.
- Excellent Castability and Fluidity:It's allows for energy-efficient production using the hot-chamber die casting method. The high fluidity enables the creation of intricate, complex parts with thin walls and excellent surface finishes.
- Dimensional Stability: Components made from zinc alloys maintain their shape and size over time, which is crucial for precision applications.
- Recyclability: Zinc alloys are fully and economically recyclable without losing their quality or performance, making them an environmentally friendly choice.
- Finish Compatibility: They can be easily plated, painted, or coated to achieve various aesthetic and functional finishes, such as a bright, durable chrome look.
