resistance alloy constantan wire

Product Overview

Description

Constantan is  a type of resistance alloy, which is made up of copper and nickel as the main components. It has a low temperature coefficient of resistance (TCR), and a wide operating temperature range (below 500°C). It has good properities on mechanical working, high resistance of corrosion. It is used for variable and strain resistance of corrosion. It is used for variable and strain resisitance elements in alternative instruments.

Factory Information

Senphus Electrical Matercal Co., Ltd was founded in 2003, which is a leading manufacturer of heating resistance alloy material in China. The main process equipments have reached the international level. The company worked out a complete, mature production process of heating alloy from smelting, steel rolling, drawing, heating treatment to the finished product, and established chemical analysis dept, physical testing dept, ect.

 

The company produces hundreds of types products with the "REOU" band, comprising over a thousand specifications under seven main categories. Copper-based low resistance heating alloys (CuNi1-CuNi44); precision resistance alloys (Karma, manganin and constantan); high resistance heating alloys (nickel-chromium alloy wire); thermocouple alloys (K, N, T, J type); thermocouple extension wire alloys; PTC thermistor resistance alloy and specialty wire (pure nickel wire and corrosion-resistant (Monel) alloy) with wire, strip, ribbon, bar, foil, sheet, stranded. The products have stable physical performance, high surface loading, oxidation resistance, high electrical resistivity and stable temperature coefficient of resistance, ect., so they are widely used in malitary project, aerospace, household appliances, heating wire, mechanical, electrical plant, temperature instruments, and many other field s. Due to the annual output of 1500 tons, and the KANTHAL level or more better quality, we become the designated supplier of many world-renowned brand.
