Iron-Chromium-Aluminum Resistance Wires

0Cr23Al5 resistance wire
- Features:
- 0Cr23Al5 is an Iron-Chromium-Aluminum alloy (FeCrAl alloy) that can be used at temperatures up to 1300°C. As an important member of the FeCrAl heating alloy series, 0Cr23Al5 has significant advantages over nickel-chromium alloys in terms of maximum service temperature, resistivity, cost, and oxidation resistance. Compared with 0Cr25Al5, it has slight advantages in cost and processing performance, but its maximum service temperature is slightly lower. Selection should be based on a comprehensive evaluation of the specific service temperature, usage environment, cost budget, and processing requirements. In high-temperature applications of 1100-1300°C, cost-sensitive situations, and applications with certain processing requirements, 0Cr23Al5 is an ideal choice. In industrial applications, 0Cr23Al5 is used for the ends of electric furnace elements and electric furnace heating elements.
- 0Cr23Al5 Resistance Wire is also known as Kanthal D, Alloy 815, Alchrome DK, Alferon 901, Resistohm 135, Aluchrom 5, Stablohm 812, KD, Aluchrom I, Icralloy 20, Alferon 20, Alloy K etc.
