0Cr15Al5 alloy wire is one of the most reliable choices for industries that need stable heating performance at elevated temperatures. As a ferritic FeCrAl alloy, it combines chromium and aluminum in balanced proportions, providing durability, oxidation resistance, and strong electrical resistance properties.

The wire is composed of iron with 15% chromium and 5% aluminum. This composition provides two major benefits: high resistivity and strong oxidation resistance. When heated, aluminum in the alloy forms a stable alumina layer on the surface. This thin yet tough oxide film protects the wire from further oxidation, extending its lifespan in harsh, high-temperature environments.
Compared to nickel-chromium wires, FeCrAl alloys like 0Cr15Al5 offer a higher operating temperature range and a longer service life, while being more cost-effective. This makes it a preferred material for applications where both performance and economic value are critical.
Applications
0Cr15Al5 alloy wire serves in a wide variety of heating systems, including:
Industrial furnaces: heating elements for steel, ceramics, and thermal processing.
Ceramic kilns and glass plants: stable heating under prolonged high-temperature cycles.
Household appliances: electric ovens, toasters, and heaters.
Laboratory equipment: furnaces and kilns used for research and testing.
Resistors: electrical components requiring precise resistance values.
Its adaptability allows manufacturers to produce it in different forms such as round wire, strip, or flat wire, and it can be wound or formed into coils to match different designs.
