Technical features
Heat-resistant chromium-nickel alloy is indispensable in modern electrical engineering. The most popular composition with 80% Ni - Kh20H80. In order to make the alloy cheaper the high percentage of Ni was reduced by increasing the proportion of iron. The alloy with higher iron content was called ferronichrome. It is used at lower temperatures. The chromium and nickel in the alloy have a rare combination of high electrical resistance (1.05-1.40 Ohmxmm2/m) and high heat resistance. The limiting operating temperature of nichromes is close to 1200 °C, and for some grades it is 1250 °C.
- Temperature coefficient of resistance - 0.0001 - 0.00025 1/K
- density - 8200-8500 kg/m³
- melting temperature 1100-1400 °C
- specific heat capacity 450 J/(kg-K) at 25°C
- ultimate tensile strength 0.65-0.7 GPa
