A rivetable deformable low-copper alloy material and its application

Abstract

Disclosed is a low-copper alloy material consisting of Al, Cu, M, Zn and unavoidable impurities, M being at least one element of Ni, V, Ti, Zr, La, Ce, Pr, Nd, Mo, Si, Be, Cr, Mn, Co and Mg, and the impurities comprising at least one element of Fe, Pb, Sn, Sb and Cd. The weight percentage composition of the low-copper alloy material is: the Al content x = 0.1 - 6.0 wt%, the Cu content y = 0.1 - 4.0 wt%, the M content z = 0.001 - 1.0 wt%, the total amount of the impurities is less than or equal to 0.1 wt%, and the remainder is Zn. The sum of the Al and Cu contents satisfies 0.5 wt% ≤ x+y ≤ 9.0 wt%, and the ratio of the Al and Cu contents satisfies 1 ≤ x / y ≤ 4. The alloy may be applied to components such as power supply plugs of household appliances, said components requiring riveting and stamping processing.

Description

technical field [0001] The invention relates to the technical field of low-copper alloy materials and their applications, in particular to a rivetable deformable low-copper alloy material and its application. The alloy material can be applied to power plugs of household appliances and other parts that need to be riveted and stamped. . Background technique [0002] Copper and copper alloys are one of the most widely used non-ferrous metals, accounting for more than half of the amount used in the electrical and electronic industry. Although the demand for copper is strong, there is a serious shortage of copper resources in my country, the supply rate of domestic resources is less than 25%, and copper prices continue to remain high. Moreover, the copper content of copper alloys is relatively high, generally above 55%, and the price of copper raw materials usually accounts for 85-90% of the selling price of copper alloys. Therefore, copper prices have a serious impact on the ca...

Although the demand for copper is strong, there is a serious shortage of copper resources in my country, the domestic resource supply rate is less than 25%, and copper prices continue to remain high

As a Zn-Al-based deformed zinc alloy, the tensile strength of the alloy is above 360MPa, and the elongation is only ≤10%, which cannot meet the requirements for riveting processing of zinc alloys for power plugs.
