Rhenium pellet material is a rare refractory metal, which not only has good plasticity, mechanical properties and creep resistance, but also has good wear resistance and corrosion resistance, and can keep most of the gas except oxygen. chemical inertness. Rhenium pellet material and its alloys are widely used in aerospace, electronic industry, petrochemical and other fields. Superalloy is the largest consumption area of ​​rhenium pellet material, accounting for about 80% of the total consumption of rhenium pellet material, and catalyst is the second largest consumption area of ​​rhenium pellet material.

The global reserves of rhenium pellet material are very small, and the price is relatively expensive, and alloys containing rhenium pellet material are mostly used in applications. As an alloy addition element, rhenium pellet material can greatly improve and improve the properties of the alloy. The rhenium pellet material can form a series of alloys with tungsten, molybdenum, platinum, nickel, thorium, iron, copper and other metals. The most important alloys are widely used in aerospace, electronics and other industrial sectors.

Rhenium pellet material can simultaneously improve the strength and plasticity of tungsten, molybdenum and chromium, which is called "rhenium effect". For example, adding a small amount (3% to 5%) of rhenium pellet material can increase the recrystallization initiation temperature of tungsten by 300°C to 500°C—the above effect of rhenium pellet material is called the rhenium effect. W-Re and Mo-Re alloys have good high temperature strength and plasticity, and can be processed into plates, sheets, wires, wires, rods, high temperature structural parts for aerospace and aviation (nozzles, nozzles, heat shields, etc.), Elastic components and electronic components, etc.
