Abstract

The invention provides a corrosion-resistant environmental-friendly zinc alloy and relates to the technical field of alloys. The corrosion-resistant environmental-friendly zinc alloy comprises the following components in percentage by weight: 3.6-5.8% of Al, 0.1-0.48% of Cu, 0.001-0.1% of Mg and the balance of Zn and inevitable impurities, wherein the mass ratio of Al to Cu is 8-30; the microstructure of the zinc alloy comprises an eta phase and a beta phase; the volume percentage of the eta phase is less than 50%. The alloy has excellent casting properties, corrosion resistance and polishingand electroplating properties, is applicable to components and elements of water heating bathroom accessories, small hardware accessories and the like manufactured through pressure casting and gravityor low-pressure casting.

Description

technical field [0001] The invention relates to the technical field of alloys, and in particular to a corrosion-resistant and environment-friendly zinc alloy. Background technique [0002] As an important non-ferrous metal, zinc is used in the third place after aluminum and copper, and zinc is used to produce zinc-based alloys, which occupies the second place in zinc consumption, mainly used in the production of die-casting zinc alloys and Gravity cast zinc alloy. [0003] Compared with other non-ferrous metals, die-casting zinc alloy has the characteristics of low melting point, good fluidity and formability, low energy consumption, and low raw material cost. The surface of die-casting castings is smooth, especially suitable for polishing and electroplating. Die-casting zinc alloys commonly used in the manufacturing industry are Zn-Al alloys containing about 4wt% Al. %), ZAMAK5 (Cu: 0.7-1.1wt%), ZAMAK7 (Cu≤0.1wt%) alloys, ZAMAK3 and ZAMAK7 alloys in this series of alloys ...
