Thread nichrome CR20NI80 - 2.4869 - Ni80Cr20

Thread nichrome CR20NI80 - 2.4869 - Ni80Cr20

Benefits of brand CR20NI80

— During long-term operation is not oxidized;
— has high strength;
— heating elements made of nichrome can withstand until the destruction of thousands of on/off cycles.(see the composition of high-temperature metals and nichrome);
— has a low coefficient of thermal expansion.
