High-Temperature FeCrAl 0Cr25Al5 Resistance Wire for Industrial Heating & Chemical Processing

Description

Discover FeCrAl 0Cr25Al5 resistance wire: superior oxidation resistance, unmatched durability in extreme temperatures (up to 1300°C), and compliance with global standards. Ideal for industrial furnaces, household appliances, and aerospace applications.

Product Overview

FeCrAl 0Cr25Al5 resistance wire is a premium iron-chromium-aluminum alloy engineered for demanding high-temperature environments. With 25% chromium (Cr) and 5% aluminum (Al), this alloy forms a protective alumina (Al₂O₃) layer under thermal stress, ensuring exceptional resistance to oxidation, carburization, and sulfurization. Its unique composition enables stable electrical resistivity (1.45 μΩ·m) and prolonged service life in temperatures up to 1300°C, outperforming traditional nickel-chromium alloys in corrosive atmospheres.

The wire’s mechanical robustness—high tensile strength (≥650 MPa) and ductility—ensures ease of fabrication into coils, heating elements, and precision components. Compliant with IEC 60216, ASTM B603, and DIN 17470, it is widely adopted in chemical processing, semiconductor manufacturing, and energy sectors. Regional adaptability makes it ideal for Southeast Asia’s humid climates, the Middle East’s sulfur-rich environments, and Europe’s stringent industrial regulations.
