Technical Characteristics
Alloy alloyed with nickel and cobalt has a minimum LCTR. The alloy has twice the electrical resistance compared to invar. The material contributes to making the strongest possible sealed joints with glass. In the 19th century, nickel alloys were very rare. Today, they are used in many applications. To buy nickel sheet, strip means to make a choice in favor of quality. Н

Sheet and strip production
Nickel is very ductile and therefore often used in the production of ultra-thin sheets. Tape grade 1.3981 is produced in lengths of up to 100 m by cold rolling. Ribbons of maximum length are allowed to have seams in accordance with GOST.
Scope of application
Medicine, power engineering, industrial chemistry, research laboratories of physics and chemistry. Aircraft construction, automotive industry. Since kovar has a high level of resistance, for electrical equipment use very thin tapes with a maximum thickness of 20 microns.
