cutting insulator Alumina Ceramic gasket spacer washer

Reputation depends on quality, quality comes from Hard!

Alumina Ceramic:

The hardness (Hr) of nano-alumina is 2700~3000, and the modulus of hesan (kg/mm2) is 35000~41000. The thermal conductivity is 0.75~1.35×103J/m·h·°C, and the thermal expansion coefficient is 8.5×10-6/°C (room temperature~1000°C). While utilizing these characteristics, people have developed Al2O3~TiO2, Al2O3-ZrO2 ceramics to improve the toughness and thermal shock resistance of nano-alumina ceramic cutters. The particle size composition of Al2O3 during the sintering process The control is an important part of determining the quality of the tool. If high temperature isostatic pressing (HIP) is used, the grain size can be 0.3~0.5 microns. The flexural strength of nano-aluminum cutters can be increased to 900-1000 MPa, which is suitable for high-speed cutting.

properties:

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
