[product description]

The silicon nitride protective tube has higher bending strength and oxidation resistance than other products. Maximum operating temperature of 1800. Also inaddit-ion to its own structure characteristics, the product also has good wear resistance and on the metal solution corrosion resistant performance, so the product can di-rectly with aluminum, zinc, copper and magnesium solu-tion contact, adhesion of aluminum ceramic protection tube has been successfully used for temperature meas-urement. Have other properties, such as high temperature resistance, high load capacity and wear resistance, etc..
