Heating Resistance Alloys

Heat-resistant alloys are alloys that can maintain high strength and certain resistance to oxidation and corrosion under high-temperature environments. These alloys are mainly used in high temperature working environment, such as aerospace, transportation and other fields, of which nickel-based alloys, heat-resistant titanium alloys, heat-resistant copper alloys, etc. are typical representatives. Heat-resistant alloys are typical representatives of heat-resistant alloys.

Nickel-based alloys: with the characteristics of maintaining high strength and oxidation and corrosion resistance at a high temperature of 650-1000℃, they are subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys and so on according to their main properties. Nickel-based alloys are widely used in aviation engines, petrochemical and other fields.

Heat-resistant titanium alloys: also known as high-temperature titanium alloys, with high strength at 400 ~ 600 ℃, mainly used in the manufacture of aero-engine compressor disk and rotor blades and other components, requiring high fatigue strength at room temperature and high temperature.

Heat-resistant copper alloy: high temperature strength, thermal conductivity, thermal stability and oxidation resistance, often adding nickel, chromium, zirconium. Titanium and other high melting point elements to form heat-resistant compounds, strengthened by heat treatment, suitable for high-temperature environment, such as electrical contact materials.

In addition, there are magnesium and thorium heat-resistant alloys and heat-resistant aluminum alloys, etc. These alloys have their own unique properties and application areas. Magnesium and thorium heat-resistant alloys based on magnesium, thorium as the basic alloying components, with good creep resistance; heat-resistant aluminum alloys in the lightweight, high strength, heat-resistant aspect Outstanding performance, especially in the 250 ℃ - 400 ℃ temperature range of lightweight high-strength aluminum alloy materials, has a high degree of competitiveness and potential applications
