High strength: Due to the excellent physical properties of zinc alloy, products made by zinc die-casting molds have high strength and rigidity. This enables zinc die castings to maintain structural stability and reliability when subjected to external forces and stresses.
Good corrosion resistance: Zinc alloy has good corrosion resistance and can remain stable in harsh environments. Products made of zinc die-casting molds can resist acid and alkali corrosion, oxidation and corrosion of corrosive media, prolonging the service life of the product.
Disadvantages of Zinc Die Casting Mold
Higher cost: Compared with other die-casting materials, the cost of zinc alloy is higher, so the price of products made by zinc die-casting molds is relatively high. This can be a limiting factor in some cost-sensitive applications.
Poor wear resistance: Compared with other metal materials, zinc alloy has lower hardness and wear resistance. Zinc die castings used in some high friction, high wear environments may require more frequent maintenance and wear faster.
Poor dimensional stability: Zinc alloys have a large shrinkage rate during cooling, which may lead to relatively poor dimensional stability of products manufactured by zinc die-casting molds. In applications with higher size requirements, additional controls and handling may be required.
Restricted material selection: As a die-casting material, zinc alloy has relatively few material types and options. Compared with other materials, zinc die casting molds have less flexibility in material selection.

Zinc die casting mold or aluminum die casting mold? Is there a better option?
Aluminum is by far the most commonly used alloy in die casting. The most common die cast aluminum alloys are A380 and A383. Both offer the best combination of material properties and castability. Aluminum alloy die castings are widely used in various industries. This alloy is commonly found in electronics, communications equipment, automotive components, gearboxes, lawn mower housings, hand and power tools, and many other products. Zinc and ZA alloys are typically used for smaller die castings or where thinner sections are required. Zinc alloys generally allow greater variation in section thickness and can hold tighter tolerances. Zinc die-cast components have higher impact strength than other common metal alloys. Additionally, since zinc and ZA alloys require lower pressures and temperatures than magnesium and aluminum alloys, die life is significantly longer with relatively minimal maintenance.
the Which alloy is best for a particular application is often determined by design specifications. The alloy generally provides physical and mechanical properties suitable for the end product application. Aluminum die-cast fabrication is best for lightweight applications, while thinner/smaller applications are best for zinc die-cast fabrication. For product designers looking for die casting suppliers, it is important to understand each alloy type offered and the benefits involved.
