Zinc Alloys Uses

Here at NGI, we offer zinc alloys, which are great for use in soldering applications, die casting and for use as a corrosion-resistant coating. Zinc is often alloyed with other types of metal in order to improve its strength and heat resistance.

The Properties of Pure Forms of Zinc

Pure forms of zinc are often used to die cast large quantities of small parts because of its high specific gravity, but it’s not preferred for many other types of applications because it is considered a weak metal that has up to 50 percent less tensile strength than steel. It is also considered brittle and only becomes malleable between 212 and 302 degrees Fahrenheit. It’s important to understand that higher temperatures don’t increase the malleability of zinc, instead, it reverts back to being brittle. Zinc does have high electrochemical properties and is great for use in batteries as well as galvanizing.
