Product Description

Nichrome tube Ni80Cr20 tube for heating elements

A Nichrome tube is a type of heating element made from a nickel-chromium alloy called nichrome.
Nichrome is a non-magnetic alloy that has high resistance to electric current and is able to withstand high temperatures.
These properties make it an ideal material for use in heating applications.

Chemical Composition: 80% nickel, 20% chrome
Resisvity: 1.09 ohm mm2/m,
Hardness: Soft, hard or semi-hard
Characteristics: Stable performance; Anti-oxidation; Corrosion resistance; High temperature stability; Excellent coil-forming ability; Uniform and beautiful surface condition without spots.

Usage: Resistance heating elements; Material in metallurgy; Household appliances; Mechanical manufacturing and other industries.

We professionally produce nickel-base alloy tape, include Ni80Cr20, Ni60Cr23, Ni60Cr16, Ni35Cr20, Ni20Cr25, NiMn, Ni200, Karma, Evanohm, NCHW, etc.
