抗脱锌金属
DZR METAL

　　两相黄铜的脱锌现象，是一种腐蚀，当接触到某些侵蚀性水时可能发生。
　　Dezincification of duplex brass, which is a form of corrosion, may occur when in contact with certain aggressive waters.
　　脱锌现象有选择的从合金中去除锌元素，造成多孔、富铜结构，降低了机械强度。应用中的阀门如果出现脱锌现象，在产品表面就会出现粉状物质或矿物污点。
　　Dezincification selectively removes zinc from the alloy, leaving behind a porous, copper-rich structure that has little mechanical strength. An in service valve suffering from Dezincification has a white powdery substance or mineral stains on its exterior surface.
　　为了解决这个问题，特殊的铜合金包含防蚀剂，并经过热处理，已经可以抵抗脱锌的服饰。
　　To overcome the problem special copper alloys, which contain an inhibitor and undergo heat treatment, have been developed which are resistant to corrosion by dezincification.
　　这种材料称为抗脱锌金属。
　　This material is known as DZR metal
