Product Description
1.Descritpion of Industrial insulating electrothermal Cordierite Ceramic ferrule for stud weldingCordierite ceramic is one of the most popular ceramics for its properties of excellent thermal stability, high refractoriness, good chemical durability, low dielectric constant, and low thermal expansion.Cordierite ceramic is extensively used in important industrial applications such as micro electronics, refractory products, heat exchanger for gas turbines, thermal shock-resistant table ware, catalyst supports, and porous ceramics. Low-expansion cordierite is suitable for being applied at high temperature circumstance where a good thermal shock resistance is required.This unique property of cordierite is caused by the negative lattice expansion in c-axis direction,which provides excellent resistance to thermal shock as well as low thermal conductivity. 2.Features & Advantages of Industrial insulating electrothermal Cordierite Ceramic ferrule for stud welding1). Strong heating ability and high efficiency2). High density3). Fine surface4). Good thermal conductivity 5). Good heat-shock resisting ability 3.Application of Industrial insulating electrothermal Cordierite Ceramic ferrule for stud welding 1)Electric appliance industry2) Automotive industry3) Mechanical industry4) Engineer industry5) Other application with high requirement of no staining6) Other application use in liquid and gas 4.Specification of Industrial insulating electrothermal Cordierite Ceramic ferrule for stud welding | Item | Test Condition | Unit&Symbol | Cordierite ceramics |
