Lead has the advantages of low melting point, high corrosion resistance, resistance to penetration by X-rays and gamma rays, and good plasticity, so it is often used for processing. Lead die casting is one of them. The rapid development of China lead die casting has also driven the development of China's economy. Next, let's take a look at some of the defects between lead-to-die castings and zinc die castings.

Aluminum alloy is much better than zinc alloy in performance. It has good die-casting performance, electrical conductivity, and thermal conductivity, as well as good cutting performance. The disadvantages are also obvious. Aluminum-silicon series alloys are easy to stick to molds, are corrosive to metal crucibles, shrink in volume, and are prone to shrinkage holes.

The most serious shortcomings of zinc alloys are aging, increased volume, and reduced strength. Excessive time will cause die castings to deform or even break, which is the main reason why the use of zinc alloys is limited.

Everything is good and bad. Although lead die castings and zinc die castings do have defects, China zinc die casting manufacturer and lead die casting manufacturer is working hard to continuously improve, and I believe they will get better and better.
