Material Notes:
LONGLY's alumina ceramic tubes and rods (the tolerances of +/- 0.02mm could be reached by mechanical or electronic finishing or mirror surface finishing) have high hardness, wear resistance, insulation and high temperature resistance. Alumina ceramic tubes are mainly applicable to the material conveying with wear resistant and heavy scouring resistant demands, such as material conveying pipelines for coal-fired power generation, metallurgical and geological industries. Meanwhile they can be used as fuse insulating tube on the electric and electronic appliances. Alumina ceramic rods are used as resistor's ceramic matrix and ceramic top pillar on two-metal thermostat.Information Provided by China Yixing Longly Refractories Co. Ltd
