The 0Cr25Al5 high temperature resistance wire is a proven solution for industries requiring reliable performance under extreme heat. As an iron-chromium-aluminum alloy, its carefully balanced composition provides outstanding resistance to oxidation, stability in high-temperature environments, and excellent longevity compared to standard resistance materials. DLX manufactures 0Cr25Al5 wire with precision, ensuring every spool meets the highest standards for heating applications worldwide.
The alloy’s formulation—approximately 25% chromium, 5% aluminum, and the balance iron—creates a protective aluminum oxide film on the surface when exposed to heat. This oxide layer acts as a shield against scaling and environmental degradation, making the wire suitable for continuous use up to 1,300°C. This is significantly higher than the operating limits of many nickel-chromium alloys, giving it a competitive edge for demanding industries.

In practical applications, 0Cr25Al5 wire is widely used in household appliances such as ovens, electric heaters, and hair dryers. In industrial settings, it is indispensable in high-temperature furnaces, kilns, ceramics processing, petrochemical heating, and metallurgical equipment. Its versatility and resilience make it one of the most trusted materials in both consumer and industrial heating elements.
Compared to NiCr alloys, 0Cr25Al5 offers superior oxidation resistance and cost-effectiveness. While NiCr wires provide better mechanical flexibility, they typically degrade faster when continuously exposed to very high heat. In contrast, the FeCrAl system, and specifically 0Cr25Al5, maintains stability and extends equipment lifespan, reducing replacement costs. This makes it an attractive option for large-scale industrial operations where downtime is costly.
