Cu86Mn12Ni Manganin Alloy Strip 1mm (T)*5mm (W) Copper Alloy Strip

1. Introduction

Manganin is a trademarked name for an alloy of typically 86% copper, 12% manganese, and 2% nickel. It was first developed by Edward Weston in 1892, improving upon his Constantan (1887).

A resistance alloy with moderate resistivity and low temperature coefficent. The resistance/temperature curve is not as flat as the constantans nor are the corrosion resistance properties as good.

Manganin foil and wire is used in the manufacture of resistors, particularly ammeter shunts, because of its virtually zero temperature coefficient of resistance value and long term stability. Several Manganin resistors served as the legal standard for the ohm in the United States from 1901 to 1990. Manganin wire is also used as an electrical conductor in cryogenic systems, minimizing heat transfer between points which need electrical connections.

3. Frequent questions

1) What is the minimum amount that the customer can request?

If we have your size in stock, we can provide any quantity you want.
If we do not have, for the reel cable, we can produce 1 reel, about 2-3kg. For the coil wire, 25 kg.

2) How can you pay a small amount of sample?

We have the Western Union account, bank transfer for the sample amount is also fine.

3) The customer does not have an express account. How will we arrange the delivery for the sample order?

You just need to provide your address, we will check the express cost, you can arrange the express cost along with the sample value.

4) What are your payment terms?
We accept L / C, T / T, also depending on load and total quantity. We talk about more details after achieving your detailed requirements.
