 Zinc aluminum die casting is ─ ─ kind of zinc as the main components of die-casting parts. The  surface of such parts - the layer is very dense surface, which is  evacuated porous structure, but also lively amphoteric metal. Therefore,  only by using the appropriate pre-treatment methods and plating  process, to ensure that the zinc alloy plating layer has good adhesion,  to meet the requirements of qualified products.Stainless steel electroplate CNC milling part Supplier

The  commonly used zinc alloy materials for electroplating are as follows:  3.5% -4.5% of aluminum, 0.75% -1.25% of copper, 0.03% -0.08% of  magnesium, the balance of zinc and the sum of impurities of less than  0.2%. The 925 grade zinc alloy high copper content, but also easy to electroplating. Normally,  the density of zinc alloy is 6.4 ~ 6.5g / cm3. If the density is less  than 6.4g / cm3, foaming and pitting will occur easily after plating. In short, the material must be strictly checked. In addition, die-casting mold must be designed to avoid the plating difficult to overcome the defects
