Problems solved by technology

However, the addition of these materials also increases the cost of zinc alloys, especially for some industries with low added value. It is not appropriate to use such zinc alloys from the perspective of cost.
[0004] In some fields, the required zinc alloy is expected to have the dual properties of die-cast zinc alloy and deformed zinc alloy. These problems have been reported by technology, which is completely superimposed on materials with die-cast zinc alloy and deformed zinc alloy. More types of materials are required, and the use of precious and rare metals has not changed

Abstract

The invention relates to a zinc alloy material, which comprises the following components by weight percent: 0.3-0.35 percent of copper, 0.5-2.5 percent of aluminum, 0.03-0.05 percent of magnesium, 0.003-0.005 percent of silicon, 0.003-0.005 percent of manganese, 0.01-0.03 percent of chromium, 0.0005-0.0008 percent of boron, 0.05-0.08 percent of bismuth, 0.005-0.008 percent of nickel and the balance of zinc. Through the technical scheme, the application range of the zinc alloy pig is greatly improved, and the use amounts of precious metal and rare metal are reduced.

Description

technical field [0001] The invention belongs to the field of alloys and relates to the application of zinc alloys, in particular to a zinc alloy material that can meet the dual requirements of die-casting and deformation. Background technique [0002] Among the existing zinc alloy materials, they are roughly divided into two types: die-cast zinc alloy and deformed zinc alloy. Among them, zinc-copper alloy is mainly used as die-cast zinc alloy. In this type of zinc alloy, the cost of the product is relatively high due to the use of copper. High, and my country is a country that is poor in copper resources. In this type of alloy, it has been seeking to use low-copper or copper-free materials to replace it. [0003] For wrought zinc alloys, in order to reduce the brittleness of zinc alloys and the activity of zinc, it is generally necessary to add nickel, titanium and other precious metals or even rare earth elements to zinc alloys to improve the performance of zinc alloys.
