Description

UNS K94610 Kovar Alloy Bar With Good Low-Temperature Tissue Stability

Kova alloy bar is also called sealing alloy or constant expansion alloy. Alloys with relatively constant low or moderate expansion coefficients over the temperature range -70 to 500 ° C. It is close to the expansion coefficient of glass or ceramic and other sealing materials, so as to achieve the effect of matching the seal. The main types are Fe-Ni, Fe-Ni-Co, Fe-Ni-Cr alloys. There are also non-oxygen copper, tungsten, molybdenum and their alloys and composites. It is mainly used as sealing material in electronic industry and electric vacuum industry.
