Alumina bushing has high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Alumina has high hardness and good wear resistance, making it a suitable material for ball valves, piston pumps, and deep drawing tools. In addition, it can be easily combined with metals and other ceramic materials using brazing techniques and metalizing.
Ceramic bushing is a ceramic connector for industry parts. Bushing can be welding, adhesive, inset with the metals use for the industry parts. Due to Ceramic bushing produced by technical ceramic with excellently properties.like a alumina ceramic bushing,zirconia bushing,siliconia bushing.
In the moving parts, because of long-term friction caused by the wear of parts, when the shaft and hole clearance wear to a certain extent must be replaced parts, so the designer in the design of the lower hardness, better wear resistance material for the shaft sleeve or bushing, so as to reduce the wear of the shaft and seat.
Alumina Tubes as a standard ceramic product. Alumina can take temperatures up to 1650°C, having extremely high temperature stability, chemical corrosion resistance, and high wear and abrasion resistance.
We offer an enhanced range of 99% alumina tubes.
