Description

The material NiCr6015 with the material number 2.4867 is applied in the form of strips and wires (see also heating conductor alloys according to DIN 17470 or electrical resistance alloys according to DIN 17471) for heating conductors and resistors. It is a nickel-iron-chromium heating conductor alloy for operating temperatures of up to 1100 °C and often contains additives of rare earths for a higher resistance to oxidation, especially with frequent switching operations or larger temperature variations. The resistance to atmospheric corrosion at 20 °C is high up to the upper operating temperature the resistance to air and other oxygen-containing gases as well as to nitrogen-containing low-oxygen gases is high as well, yet it is low to oxidizing as well as reducing gases containing sulphur. The resistance to carbonizing is high. The alloy has a relatively high temperature-resistance coefficient. Application for heating elements in household and industrial devices (high-ohm electric resistors).
