High specific gravity tungsten alloy has high density, high strength, good plasticity and machinability, good conductivity and thermal conductivity, good corrosion resistance, good weldability and excellent absorption ability to various rays. The main mechanical and physical properties of high specific gravity tungsten alloy are particularly * show. The application and preparation method of high specific gravity tungsten alloy are introduced in detail below.
Application of high specific gravity tungsten alloy:
High density tungsten alloys have been widely used in national economy and national defense industry. Aviation and aerospace industries are used for gyroscope rotor, counterweight and balance materials, as well as guiding devices and damping devices; Petroleum industry, nuclear industry and medical device industry are used as shielding materials to prevent various rays; In the mechanical industry, it is used as die-casting mold, tool holder, boring bar and automatic watch hammer; The weapon industry is used as armor piercing material and shaped charge cover material; Used as 284 'rivet head and switch contact material in electrical industry; Sporting goods can also be used as golf racket counterweight materials.
Preparation method of high specific gravity tungsten alloy:
The key of alloy preparation process is sintering process. The sintering temperature is generally 1400 ~ 1600 ℃, and liquid phase is produced, which is conducive to the densification of the alloy. The sintered alloy can reach more than 99% of the theoretical density. The sintered products can also be treated by heat treatment to improve the plasticity and strength, and then processed by pressure, and their mechanical properties can be significantly improved.
