What are the advantages of using zinc alloy materials for metal keychains?

Characteristics of zinc alloy material:

Zinc alloy is an alloy composed of zinc and other elements added. Commonly added alloying elements include low-temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has a low melting point, good fluidity, easy to weld, braze and plastic process, corrosion resistance in the atmosphere, and easy recycling and remelting of residual waste; but its creep strength is low and natural aging is easy to cause dimensional changes. Prepared by melting method, die-casting or pressure-processed into material.

According to the manufacturing process, it can be divided into cast zinc alloy and wrought zinc alloy. The main added elements of zinc alloy are aluminum, copper and magnesium. Zinc alloys can be divided into deformation and cast zinc alloys according to the processing technology. Cast zinc alloy has good fluidity and corrosion resistance


1. Relatively heavy.

2. Good casting performance, it can die-cast precision parts with complex shapes and thin walls, and the surface of the castings is smooth.

3. Surface treatment can be carried out: electroplating, spraying, painting, polishing, grinding, etc.

4. When melting and die-casting, it does not absorb iron, does not corrode the pressure and does not stick to the mold.

5. It has good mechanical properties and abrasion resistance at room temperature.

6. Low melting point, melting at 385℃, easy to die-cast molding

The characteristics of zinc alloy help It has the characteristics of being shaped, easy to engrave and easy to save in the process of making the keychain. Most high-end metal keychains on the modern market are made of this material. For example, BMW keychains, Audi keychains, and Volkswagen keychains produced by Shenzhen Onik mostly use this material. In addition, this material is easy to mold, so it can produce a variety of keychains

The car logo keychain is a newly developed zinc alloy automotive product. Anti-rust treatment by dripping oil or plating rare metal; it is an exquisite small gift for car owners in the promotion of car 4S shop, and it is also an essential car accessories, car accessories, and personalized fashion products for car owners.

Product use: corporate brand promotion, new product promotion, souvenirs and other industries commemorative promotional items. At present, the surface of zinc alloy is mainly plated with anti-rust elements such as nickel or rhodium. The keychain has become a small gift.

The most important thing is that the customer chooses the keychain of the right material.
