Six-element brass alloy with high strength and corrosion resistance

Abstract

The invention relates to a six-element brass alloy with high strength and corrosion resistance, and the objective of the invention is to provide a high strength corrosion-resisting six-element brass alloy with high intensity and high elongation percentage. The six-element brass alloy comprises the following components by weight percentage: 55.00-95.00% of Cu, 0.05-19.00% of Mn, 0.05-1.50% of Fe, 0.01-6.50% of Ni, 0.01-0.5% of Ag and 3-42.00% of Zn; the elements are smelted according to present technology, and the six-element brass alloy with high strength and corrosion resistance is obtained.

Description

technical field [0001] The invention relates to a high-strength and corrosion-resistant six-element brass alloy. Background technique [0002] At this stage, the copper-based materials selected by electrical and electricians, low-voltage electrical appliances and electronic connector industries widely use brass materials and tin phosphor bronze materials to produce copper-based materials such as plug-and-play components, wiring harnesses, sockets, and household appliance plugs. The corrosion resistance is poor, and the surface needs to be tin-plated or chrome-plated to prevent oxidation and discoloration. However, with the rapid development of our country's economy, the country's emphasis on environmental protection has increased year by year, and the environmental protection standards formulated have become more and more stringent. However, the electroplating process is prone to pollution. In order to meet environmental protection standards, relevant companies have to inves...

Problems solved by technology

However, with the rapid development of our country's economy, the country's emphasis on environmental protection has increased year by year, and the environmental protection standards formulated have become more and more stringent. However, the electroplating process is prone to pollution. In order to meet environmental protection standards, relevant companies have to invest a lot of money every year. The transformation and upgrading of environmental protection facilities will lead to an increase in the operating costs of the enterprise

In addition, in recent years, the price of non-ferrous metals has skyrocketed and remains high. The price of non-ferrous metal raw materials has been running at a high level for a long time; high-purity tin, nickel plates and industrial silver used in electroplating are even rare and precious metals. These factors have directly contributed to the cost of electroplating. increase

However, if the existing common brass alloys increase the strength by adjusting the composition, the loss of elongation will be very severe, and they cannot be used for the production of elastic components at all; and common brass alloys are used for stamping structural parts due to their poor corrosion resistance. When, also had to be tinned or nickel-plated
