Zinc alloy die casting factory features 
 1 light weight. 
 2 casting performance, and can be die-casting complex shapes, thin-walled precision castings, smooth surface. 
 3 can be surface treatment: electroplating, spraying, painting. 
 4 is not melting and casting of iron absorption, non-corrosive pressure-type, non-stick mode. 
 5. Has good mechanical properties and wear resistance at room temperature. 
 6 low melting point, melting at 385 ℃, easily die-casting. My company produces various grades of zinc alloy, can also produce according to customer requirements. The factory produced good quality zinc, zinc residue less the quality of an ingot and other cheap, there is need; can contact me, and look forward to your patronage, we will look forward to you the best service attitude of patronage 
 The company spirit of "customer first, honesty first" principle, with the number of enterprises established long-term relationship.

 2 is a variety of zinc alloy zinc alloy, the highest hardness and strength. Its copper content (3%) has good resistance to creep (deformation temperature by force) and anti-wear properties, 
 2 zinc alloy used for gravity casting, such as the manufacture of metal mold or injection molding tools. 

 3 zinc alloy casting and dimensional lasting stability, so that over 70% of the zinc alloy die-casting products are made of zinc alloy 3. 
 3 zinc alloy plating, painting and chrome surface treatment and so on. Widely used in automobiles, motorcycles, electronic communications, instrumentation and other mechanical parts; as well as toys, ornaments, cutlery, locks and other high-level hardware devices. 

 4, began in Asia zinc alloy, copper, zinc levels between 3 and 5, between zinc. 
 4, No. 3 zinc alloy is more effective than reducing some of the casting mold sticking phenomenon, and 4 zinc alloy and 3 remain quite soft. Mainly used in bathroom accessories, kitchen utensils and zipper top. 

 5, No. 3 zinc alloy zinc alloy than the hardness and strength. 
 5 zinc alloy is due to changes in the characteristics of joined the 1% copper, this alloy casting of excellent against creep (when the deformation temperature heat) than 3 zinc alloy is good, do plating, machining and general surface treatment, for sports equipment and industrial parts. 
 8, widely used in high pressure zinc alloy casting. Than 3 zinc alloy and zinc alloy No. 5 has high hardness, strength and creep degrees (when the high temperature deformation of the force). 
 No. 8 is also suitable for electroplating and other surface treatment, process the same with 5 zinc alloy. Mainly used for decoration materials.
