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. 2.

Mechanical Properties
Application of Constantan Constantan is a copper-nickel alloy that contains specific minor amounts of additional elements to achieve precise values for the temperature coefficient of resistivity. Careful control of melting and conversion practices results in a very low level of pinholes at ultra-thin thicknesses. The alloy is used extensively for foil resistors and strain gauges. FAQ 1. What's the minimum quantity customer can order? If we have your size in stock, we can provide any quantity you want. If we do not have, for spool wire, we can produce 1 spool, about 2-3kg. For coil wire, 25kg. 2. How can you pay for small sample amount? We have Western union account, wire transfer for sample amount also ok. 3. Customer do not have express account. How will us arrange the delivery for sample order? Just need to provide your address information, we will check the express cost, you can arrange the express cost together with sample value. 4. What's our payment terms? We can accept LC T/T payment terms, it also depending on delivery and total amount. Let's talk more in details after getting your detailed requirements. 5. Do you provide free samples? If you want several meters and we have stock of your size, we can provide, customer need to bear the International express cost. 6. What's our working time? We will give you reply through email/phone Online contact tool within 24 hours. No matter working day or holidays. Any questions pls kindly send email to us,thank you. |
