Product Details

1. Ni80Cr20 strip, also known as Nichrome strip, is a type of resistance heating alloy made of 80% nickel and 20% chromium. This alloy is widely used in the manufacturing of heating elements due to its excellent resistance to oxidation, high melting point, and ability to generate heat efficiently. Ni80Cr20 strip is commonly used in applications such as electric ovens, toasters, industrial furnaces, and other heating devices where high temperatures are required. Its properties make it a reliable and durable material for various heating applications.

2. Main Types of Nickel chrome alloys: Ni80Cr20, Ni70Cr30, Ni60Cr15, Ni35Cr20, Ni30Cr20
FeCrAl alloy: 0Cr25Al5, 0Cr23Al5, 0Cr21Al4, 0Cr27Al7Mo2, 0Cr21Al6Nb, 0Cr21Al6.
Copper nickel alloy: CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi23, CuNi30, CuNi44

3.The size of Ni80Cr20 strip can vary depending on the manufacturer and the specific requirements of the application. Common sizes for Ni80Cr20 strips include:

Thickness: Typically ranges from 0.1 mm to 5 mm

Width: Usually varies from 1 mm to 100 mm
