Kanthal® A-1 FeCrAl Alloy Wire Mesh – Alloy Overview
Kanthal A-1 FeCrAl alloy wire mesh is a ferritic iron-chromium-aluminium (FeCrAl) alloy used primarily in electrical resistance heating elements, and other high-temperature settings, up to 2550°F. In addition to other beneficial properties, Kanthal A-1 wire cloth offers both excellent oxidation resistance and high resistivity. It is often chosen over Nichrome V 80/20 (Chromel® A), one of the oldest resistance heating alloys, when higher temperature use, longer life, and higher resistivity levels are required (not to mention its cheaper cost!). Some characteristics of Kanthal A-1 FeCrAl alloy wire cloth which dictate its use are:
- Ferritic iron-chromium-aluminium (FeCrAl) alloy.
- Nominal composition of 22% chromium, 5.8% aluminum, and iron balance.
- Very magnetic in all conditions.
- Excellent oxidation resistance and high resistivity.
- Good resistance to sulfur and carburizing settings.
- Useful in high-temperature settings up to 2550°F.
- Can be cut, formed, and welded.
Industries & Applications
Kanthal A-1 FeCrAl alloy wire cloth is principally used in high-temperature appliances and electronics given its low density, high resistivity, and superior high-temperature resistivity.
