Alumina fibres have a lower thermal conductivity and heat capacity. The temperature of long-term usage is higher than that of ordinary aluminum silicate (1000 1100 degC). It can be used with acidic atmosphere, oxidizing environment, reducing atmospheric and vacuum. It is also resistant to corrosion when used in alkaline environments, but can be easily corroded by vanadium and lead pentoxide. This type of fiber is used primarily in steel industry as a heat insulation for furnaces such as ceramic firing kilns. Pyrolysis furnaces and combustion furnaces. In batch operation, this furnace can increase output to a great extent. Alumina can also be used to transport catalysts in the chemical industry. Insulation material for nuclear reactors or space shuttles. Light alloy reinforcements. The industrial high-temperature field has a significant energy saving effect. Alumina short fibre has excellent resistance to high temperatures and is used primarily as a heat insulating refractory and as a material for body linings in metallurgical and ceramic sintering ovens or other high temperature furnaces. Low density. Its low density and good heat insulation can help reduce the quality and size of the furnace. This can also increase the precision in temperature control and improve energy efficiency. The energy saving effect of alumina fibre in high temperature furnace is superior to that of refractory or high temperature coating. The energy saving is greater than heat loss. This is because not only does the heat loss decrease, but the furnace gases are also strengthened. Convective Heat Transfer, so the furnace wall gets more heat and then transferred to the material via the national emblem.

Highlights on environmental protection and recycle applications
Alumina fibres are used to protect the environment and recycle technologies because of their chemical resistance. The alumina fiber, for example, can still be used to line the exhaust gas equipment of automobiles after it has been burned. This is because the fiber exhibits excellent corrosion resistance. Aluminum alloy plugging can be made with Saffil fiber alumina. It expands less when the temperature increases, approximately 25% less than pure aluminum, which helps the piston and the cylinder to match well, and saves fuel.

Benefits of Enhanced Composite Material Performance
Alumina fibers and metal matrix composites have improved mechanical properties and wear resistance. They also reduce the coefficient of thermal expansion. Alumina fiber reinforced metallic matrix composites are used in automotive piston blades and rotary compressor blades. The alumina composite material, which is well-bonded with the resin matrix and has greater elasticity and compressive strength than the carbon fibre, is replacing both the glass and carbon fiber in many fields. In the stationery industry, the material can be transformed into fishing rods in various colors, golf ball, snowboard, tennis rackets or other products.

The Alumina Long Fiber Reinforced Metal Matrix Composites are used for mechanical components that have high load, high temperature, high speed, and also high performance and light weight requirements. These include automotive connecting rods, transmissions rods, brake pads, and other parts, and helicopter transmissions. Device, etc. Recently, researchers began using it as a lining for thermonuclear heat exchangers that cool the reactors.
