Alumina Ceramic Header Assembly
1. Description:
The new energy series ceramics are produced by high purity complex alumina and nano metallization. It is suitable for brazing of different materials such as copper, aluminum and felling. It is applying to HVDC Relay ,sealed disconnect switch ,made of 95% aluminum oxide.
Our product is manufactured using high-quality aluminum oxide and copper, with a thick-film nickel plating technology that ensures great limberness and good corrosion resistance. The open mould design offers high intensity and good high-temperature resistance performance, while maintaining high purity for maximum effectiveness.
