SPARK HRE 1350℃ High-Performance FeCrAl Resistance & Electric Heating Wire
The SPARK HRE brand electric heating alloy is an independently developed, high-performance material by Shougang Gitane, designed specifically for extreme thermal environments. Engineered to operate continuously at temperatures up to 1350℃, HRE is a cornerstone in the field of high-temperature furnace technology.
Product Introduction
By utilizing advanced smelting and refining processes, HRE forms a dense, protective oxide film on its surface, which significantly enhances its oxidation resistance and extends its service life. This series fills a critical gap in domestic electric heating alloy materials for applications above 1350℃, offering independent intellectual property and world-class reliability for both powder metallurgy and diffusion furnace systems.
Product Features
Extreme High-Temperature Resistance: Capable of stable operation in high-temperature environments up to 1350℃.
Excellent Oxidation Resistance: Quickly forms a dense Al₂O₃ protective film to resist high-temperature oxidation and corrosive media.
Superior Flexibility: Features excellent entanglement and flexibility at room temperature, making it easy to process into complex shapes.
High Resistivity: A stable resistivity of 1.45±0.07 Ω·mm²/m allows for high power density design and energy efficiency.
Strong Deformation Resistance: Optimized alloy structure provides high resistance to high-temperature deformation (Collapse Resistance).
Long Service Life: Proven through “Rapid Test Life” standards, offering extended reliability in continuous and cycling heating applications.
