Product Description

Nichrome Alloy Resistance Wire Overview

Nichrome wire, particularly the Cr20Ni80 and Cr15Ni60 alloys, is engineered for superior performance in electrothermal applications. These alloys feature minimal electrical resistance when heated, excellent high-temperature strength, and exceptional ductility for various manufacturing processes.

Key Product Features

Low electrical resistance at elevated temperatures
High temperature strength and structural stability
Excellent ductility for machining, welding, and forming
Non-magnetic properties (Cr20Ni80, Cr30Ni70)
Melting temperature up to 1400°C
Available in multiple forms: wire, flat wire, strip, and bar
