Physical and Mechanical Properties of Sundear FeCrAl Resistance Alloy wire
Key Features & Benefits
Premium FeCrAl (Iron-Chromium-Aluminum) Resistance Heating Alloy Wire – High-Temperature Performance & Oxidation Resistance
Extreme Temperature Stability
Capable of withstanding continuous operating temperatures up to 1400°C (2552°F), significantly higher than most NiCr alloys.
Excellent High-temperature Oxidation Resistance
Upon heating, FeCrAl forms a protective, self-insulating layer of aluminum oxide (Al2O3), which prevents further corrosion and extends the life of the element.
Excellent Formability
Our wire is annealed for optimal ductility, making it easy to coil and shape without compromising structural integrity.
High Electrical Resistivity
With higher resistivity than NiCr, FeCrAl allows for more compact element designs and weight savings.
Cost-Effective Durability
Free of expensive nickel, this alloy offers a more stable pricing structure while providing a longer service life in sulfur-containing atmospheres.
