Abstract

The invention discloses a copper and tin alloy. The copper and tin alloy comprises, by mass, 4-15% of Se, 7.5-8.5% of Al, 2.0-5.0% of Zn, 2.5-3.0% of Fe, 0.05-2% of P, 0.1-0.3% of rare earth, 1-2% of Ni, 1.2-1.8% of C, 0.5-4.0% of Si, and the balance of Cu and few impurities. The copper and tin alloy has the characteristics of good toughness, good corrosion resistance, good pressure and high-temperature resistance, and convenience in machining. The copper and tin alloy still keeps above good characteristics under low temperature conditions, so the copper and tin alloy has good application values and good application prospect.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal materials, and in particular relates to a copper-tin alloy. Background technique [0002] Copper-tin alloy refers to a binary alloy mainly composed of metallic copper and metallic tin. Copper-tin alloys are widely used in condensers and heat exchangers under high temperature and high pressure, and are widely used in ships, power stations, petroleum and petrochemical, medical equipment and other departments. Copper alloys are mostly used in high temperature, high pressure, and highly corrosive environments. Therefore, there are high requirements for the corrosion resistance, compression resistance and high temperature resistance of copper-tin alloys. [0003] Traditional copper alloys are difficult to meet the current requirements for copper alloy materials, which are specifically reflected in: 1. In the case of high salt and high alkali such as seawater, the service life of traditional ...
