SPARK 00Cr20Al6 High-Performance Electric Heating Wire (1350℃)
SPARK 00Cr20Al6 is a premium ultra-low carbon, high-temperature oxidation-resistant alloy primarily composed of Iron, Chromium (20%), and Aluminum (6%). Developed by Shougang Gitane, this alloy is specifically engineered for industrial environments requiring long-term stability and extreme thermal resistance up to 1350℃.
Product Introduction
Unlike traditional nickel-based alloys, 00Cr20Al6 provides a highly cost-effective solution without compromising on mechanical strength or corrosion resistance. It is an indispensable material choice for manufacturing boiler components, gas turbine blades, and high-temperature heat treatment equipment, meeting the most rigorous international industrial standards.
Product Features
Excellent Oxidation Resistance: The 6% Aluminum content enables the formation of a dense, protective alumina film, preventing performance degradation in extreme heat.
Ultra-High Temperature Stability: Supports long-term use at temperatures up to 1350℃ with minimal resistance drift.
Cost-Effective Solution: As a nickel-free alloy, it provides high corrosion resistance and mechanical strength at a more competitive price point than high-nickel alternatives.
Advanced Production Technology: Manufactured using Gitane’s precision smelting and refining processes to ensure uniform alloy composition.
Superior Processing Capability: Supplied in various forms, including linear wire, thick strips, and thin strips, suitable for complex element designs.
Environmental Resilience: Optimized for clean energy sectors, including solar PV and semiconductor heat treatment.
