Working in a zinc alloy die Casting factory, I often encounter some questions. Why use alloys instead of pure zinc in pressure die-casting? today let me explain their character. then you will understand why we use Zinc alloys instead of pure zinc in Pressure die casting.
Zinc is a very rich mineral resource on the earth. After mining, flotation, calcining, and electrolysis, high-purity (above 99.995) zinc can be extracted. It is pure zinc ingot.
Pure zinc Have below specification
Soft due to the fast heat conduction
Poor thermal stability
Easy to deform when heated
Based on Above Character, Pure Zinc Rarely can be directly used to process casting or Die casting . We have to Improve its shortcomings, give play to its advantages, and make this excellent metal shine in our daily lives.After continuous improvement and testing, zinc alloys have gradually become familiar to us.
Zinc alloys are alloys based on zinc added with other elements. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, and titanium. Improve the forging performance and mechanical properties, physical properties and chemical properties of pure zinc.
Zinc alloy has below specification
Low melting point
Easy to weld, braze and great manufacture processing
Corrosion resistance in the atmosphere
The residual waste is easy to recycle and remelt.
Zinc alloy has good fluidity and corrosion resistance, easy processing, colorful surface treatment, high strength, and can be produced precision die Casting parts, making it more and more favored by manufacturers and die-casting factories; we are expert on Zinc Die Casting Manufacturing and Aluminum die casting produce. please contact us today, if you have zinc alloy die casting parts need to be produced.
