Product Description
Cr20Ni35 (also known as a nickel-chromium-iron resistance alloy) is a high-performance heating wire specifically designed for electric ovens, furnaces, and other thermal appliances. With approximately 20% chromium and 35% nickel content balanced with iron, it provides excellent electrical resistivity (around 1.04-1.09 μΩ·m), strong anti-oxidation properties, and mechanical stability at elevated temperatures.
This durable nickel chrome resistance wire maintains consistent heating output while resisting corrosion and scaling, making it the preferred choice for manufacturers of household and commercial electric ovens, toasters, and industrial heating systems.
