Featured! High Quality Zinc Alloy

Alloy 2 have the highest strength and hardness in all of the low aluminum zinc alloys. It contains 3% copper and has good wear properties, and may eliminate bushings and wear inserts in die-casting designs. Alloy 2 can be used at gravity cast, such as metal.
Over 70% of all zinc die-castings are made from Alloy 3 for its excellent balance of desirable physical and mechanical properties, superb cast ability and long-term dimensional stability, Alloy 3 also offers excellent finishing characteristics for electroplating, painting and chromate treatments, and usually used in car assembly, decorations, tableware etc.
Alloy 4 was developed in Asia. The content of copper is between Alloy 3 & Alloy 5. Alloy 4 has been found to deduce the effects of die soldering that occurs in some castings than Alloy 3, but still retains similar ductility with Alloy 3. It can be used at bathroom accessories, kitchen accessories and zipper top. Lars with ductility Alloy 3. It can be used at bathroom accessories.
Alloy 5 is stronger and harder than Alloy 3. It contents 1% copper, the excellent cast ability as well as improved creep performance over Alloy 3. It is readily electroplated, finished and machined. It can be used in sport appliance and industrial assembly.
Alloy 8 is used on hot chamber. It has higher strength, hardness and creep properties than Alloys 3 & 5. It is readily electroplated, finished and machined. It can be used in decoration.
Environmental protection low-temperature zinc alloy
Our enterprise specialize in produce centric casting special Environmental protection low-temperature zinc alloy
The features are:
Accord with occident RHOS and sanitation standard (no plum bum, on cadmium)
Zinc alloy obtain the perfect and smooth surface, suitable for cast various complicate Special-shaped and thin-wall hardware
The organization of the crystal is closely. Assure the dimension tolerance smallest, surface excellent and few defect.
The melting point is low, suitable to the silica gel mould. Thus the cost of the mould should be reducing. Especially apply to the casting, which are quick delivery and few amount.
Good for electric plating.
