What metal are most Zipperpers made of?

Metal Zippers are mainly made of brass, nickel and aluminium. But do you know about titanium Zippers?

Titanium alloy Zipper, a kind of Metal Zipper with Zipper teeth made of titanium aluminium alloy, the original colour is silver white, different from the copper Zipper with brass as Zipper teeth, the titanium alloy Zipper made of this titanium aluminium alloy, it has the following characteristics:
1. Over environmental protection standards.
The titanium alloy Zipper is made of titanium aluminium alloy, which is a non-magnetic, environmentally friendly and energy-saving material that can be relied upon to contain all heavy metals within environmental standards. However, the teeth of the chain are divided into environmental plating and non-environmental plating, so please note clearly when placing your order.
2. Lightweight material and high strength.
The density of titanium is 4.54g/cm3, 43% lighter than steel, and the density of aluminium is 2.7g/cm3, which makes the material lighter than brass and no less strong. At the same length, its weight is approximately 60% of that of a brass metal Zipper. Used for bags and garments are lighter, especially suitable for sewing light fabrics.

4. Good resistance to oxidation and corrosion.
The surface colouring of the titanium alloy Zipper is the same as the oxidation colouring of the copper Zipper. The surface electroplating layer is more wear-resistant and more solid, and its oxidation resistance and corrosion resistance is better than that of the copper Zipper in the humid atmosphere and seawater medium, and it is resistant to high and low temperatures, and long-distance sea transportation is not affected.
