Abstract

The invention discloses a high-strength corrosion-resistant brass material and a preparation method thereof. The brass material is prepared from the following components in percentage by mass: 60.9-64.2 percent of Cu, 0.85-1.3 percent of Si, 0.13-0.21 percent of Fe, 1.69-1.97 percent of Al, 0.71-1.58 percent of Ni, 0.1- 0.27 percent of Sn, 0.07-0.26 percent of Nd, 0.01-0.065 percent of Os, 0.03-0.12 percent of Ti, 1.1-2.25 percent of Mn, 0.01-0.07 percent of B and the balance of Zn and inevitable impurities. The preparation method for the high-strength corrosion-resistant brass material is simple in process, and the obtained brass material is high in strength and hardness, good in corrosion resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of copper materials, in particular to a high-strength corrosion-resistant brass material and a preparation method thereof. Background technique [0002] Copper has physical and chemical properties similar to precious metals, especially excellent electrical conductivity, thermal conductivity, corrosion resistance, plasticity and ability to withstand cold and hot processing. It has been widely used in electrical, electrical, mechanical and transportation vehicle manufacturing, chemical , defense and construction fields. Brass is a copper-based alloy with zinc as the main alloying element. It has been widely used in various fields of the national economy. For example, it is often used to manufacture valves, water pipes, connecting pipes for internal and external air conditioners, and radiators. With the development of social economy, the demand for brass products is increasing, and the requirements for its per...
