1.WHY CHOOSE WISDOM HIGH QUALITY CUNI44/CONSTANTAN ALLOYS?
All our raw material is made from prime material, not recycle material. We have more than 25 years experience in manufacturing resistance heating alloys.
In the market, not all the CuNi44/Constantan alloys are with standard chemical composition and stable resistance. Professional and reliable is the soul of our business.
2.DESCRIPTION OF CUNI44/CONSTANTAN ALLOYS:
CuNi44, also called Constantan, has a very low temperature coefficient, high electrical resistance, high ductility and non-corroding properties. It is suitable for use at temperatures up to 600°C (1110°F). As a very malleable, very ductile alloy, it has a very good resistance to oxidation.
The alloy is non-magnetic. It is suitable for electrical resistors, potentiometers, heating wires, heating cables and mats. Ribbons are used for heating of bimetals. Another field of application is manufacturing of thermocouples because it develops a high electromotive force (EMF) in association with others metals.
3.WISDOM ALLOYS CHARACTERISTICS:
1)Manufactured according to international quality. System (ISO9001)
2)Stable resistance and long-life span
3)Mill test certificate will be provided after production
4)Size range wire:.0.018-10mm ribbons: 0.05-0.2*2-6mm strips: 0.05-5*5-250mm
5)Good packing methods to keep goods no damage during delivery
6)Customized lable, packing, OEM service
7)24 hours after-sale service
