High temperature resistant material refers to the material that can withstand certain stress under the temperature above 550 ° C and has the ability of oxidation resistance and thermal corrosion resistance. Such material is widely used and often used in some high-temperature fields such as engine, rocket engine, aircraft, rocket tail and boiler. It is a very practical material. Of course, it has also been widely used.

Some of our common high-temperature resistant materials include ceramics, magnesium aluminum compounds, mica, corundum, silicon, graphite, titanium alloy, diamond, tungsten, silicon dioxide, silicon carbide, carbon, copper oxide, iron oxide, iron powder, manganese dioxide, etc. among them, ceramics are the most familiar high-temperature resistant materials. And these high-temperature materials not only have their high-temperature properties. Many materials have special properties. Such as cold resistance, insulation, ozone resistance and atmospheric aging resistance.

Superalloy: also known as superalloy, the service temperature range is 550-1100 ° C

Dispersion strengthened alloy: metal and alloy powder are mechanically alloyed by adding a small amount of refractory oxide (such as yttrium oxide) through the action of high-energy grinding balls to obtain high-temperature alloy powder containing dispersed fine oxide particles, which can be made into combustion chamber or turbine blade by pressing, sintering, extrusion or rolling into rod or plate, welding, heat treatment and machining.

Refractory alloy: the formation of refractory metal tungsten, molybdenum, tantalum and niobium as substrates, adding solid solution strengthening elements, carbide precipitation temperature, material strengthening mode phase and thermal processing.

Ceramic material: it can withstand a temperature of more than 1370 ° C, which is one of the most familiar high-temperature materials.
