Product Description

Constantan Wire:


1. Energy saving
2. Anti-corrosion

Our company has its own alloy smelting industry, Jiangyin Chengxin Alloy Material Co., Ltd, then we can make sure high quality twin conductor heating cables are manufacturing. One of the procuct materials copper is from Chile, and the nickel is from Jinchuan, the famous and high quliaty nickel production base.

Constantan is a copper-nickel alloy usually consisting of 55% Copper and 45% Nickel. Its main feature is its resistance which is constant over a wide range of temperatures. It is also called Alloy 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 44, CuNi 44, CN49.

Other grade of copper nickel alloy are as follows:

CN5, CuNi2

A60, Alloy 60, 60 Alloy, MWS-60, Lohm, HAI-60, CuNi 6, Alloy 260, Nickel Alloy 60, CN10
