Descripción del producto

Nichrome Alloy Wire Introduction
 

 

 

Cr*5Ni*0 is an ideal material, it has good ductility,workability and weldability under high temperature and seismic strength.

 

Nickel-chromium alloy with high and stable resistance, corrosion resistance, surface oxidation resistance, excellent coil-forming ability.

 

 

Property:

 

 

 
  • Not becoming brittle after long-term use and cooling down;
  • Resistance to oxidation: Most metals oxidize quickly and become brittle and break when heated in air. However, when heated to red-hot temperatures, nichrome wire, develops an outer layer of chromium oxide, which is thermodynamically stable in air, is mostly impervious to oxygen, and protects the heating element from further oxidation.
  • Good Ductility: remaining ductile, even after long-term usage;
  • Excellent weldability and etc.
