Technical characteristics
Alloy doped with Nickel and cobalt, has a minimum LCTR. The electrical resistance of the alloy in less than two, compared with Invar. The material contributes to the creation of the most durable pressure tight joint with the glass. In the 19th century, Nickel alloys was very rare. Today they are used in many fields. Buy Nickel sheet feed means to make a choice in favor of quality. N
