What are the metals used for building bag hardware in leather accessories?

Looking at a handbag, there are zipper to keep the bag closed and slider added to the strap to shorten and lengthen it up.

If you are interested in leathercraft or leatherwork, and you need products such as Dog Hooks, Rings, Locks, Buckles, Studs, Logos, Cord Stoppers, Bag Feet, Ornaments, Frames, or Holders, you maybe want to know what are the raw materials been used to produce the fashion accessories?

These kinds of hardware are made of raw material such as iron, copper, zinc or aluminum. The most popular material making bag hardware is zinc alloy. Zinc alloy is more stable than iron and not easy to rust, and cheaper than copper and aluminum alloy.

Zinc alloys are alloys based on zinc with other elements added. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium, and the like.

What are the advantages and disadvantages of zinc alloys of bag hardware?

Advantages: Cast zinc alloy has good fluidity and corrosion resistance. It can die-cast complex and thin-walled precision parts, and the surface of the casting is smooth.

Disadvantages: The most common defect of zinc alloy die castings is blistering on the surface. The solubility of Pb, Sn and Cd in zinc alloy is very small, so they concentrate on the grain boundary and become cathode. The solid solution rich in Al becomes anode. In the presence of water vapor (electrolyte), intergranular electrochemical corrosion is promoted. Die castings are aged due to intergranular corrosion. Zinc alloy die castings should not be used in high and low temperature (below 0℃) working environment. Zinc alloy has better mechanical properties at room temperature. However, the tensile strength at high temperature and the impact performance at low temperature are significantly reduced
