1. The advantages and disadvantages of zinc alloy:
Advantages: Cast zinc alloy has good fluidity and corrosion resistance. It is suitable for die-casting instruments and automobile parts shells.
Disadvantages: The most common defect of zinc alloy die castings is blistering on the surface.
2. Advantages and disadvantages of aluminum alloy:
Advantages: aluminum alloy has low density, but relatively high strength, close to or exceeds high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the amount of use is second only Yu Gang.
Disadvantages: During the production process of aluminum alloys, casting defects such as shrinkage holes, blisters, pores and slag inclusions are prone to occur.
