Ceramic Ferrule

Descripción del producto

ceramic ferrule for stud welding is formulated with cordierite.and by molding,vinegar,calcining,etc.The specification is as follows:Φ6、Φ8、Φ*0、Φ*3、Φ*6、Φ*9、Φ*2 ordinary and penetrable etc.
ceramic ferrules is widely used for magnetic force floating railway engineer,building bridge,building railway,large power plant,plane depot that needs wide span.

The main chemical ingredient of cordierite is 2MgO.2Al2O3.5SiO2, main material is steatite, clay, alumina, feldspar,etc. It is made by normal ceramic technique, such as dry press. They can be used for loop framework, insulators of arc-resistance, element of composite materials, burnable nozzle of electrical insulators,and etc
