Copper Manganese Alloy Wire

Posted by taeminjiayuan on April 4th, 2017

Copper Manganese alloy mainly composed of Copper, Manganese and Nickel. The CuMn alloy have high resistivity and narrow resistance temperature coefficient. The thermal emf against copper is low and it also have long term stable resistance, so the CuMn alloy is a kind of excellent precision resistance material. It is widely used as standard resistor, resistor parts and shunt resistor part.

OHMALLOY can provide the following grade copper manganese alloy:

Alloy Type		Chemical composition %						Density g/cm3	Melting Point ℃	Resistivity (μΩm)(20℃)	Tensile Strength N/mm2	Elongation (%)	Max continuous service temp (℃)
Alloy Type		Cu	Mn	Ni	Cr	Al	Fe	Density g/cm3	Melting Point ℃	Resistivity (μΩm)(20℃)	Tensile Strength N/mm2	Elongation (%)	Max continuous service temp (℃)
Manganin (Cu-Mn alloy)	6J12	Rest	11-13	2-3	-	-	-	8.4	960	0.47±0.03	490-539	10-30	50
	6J13	Rest	11-13	-	-	-	-	8.4	960	0.44±0.04	490-539	10-30	80
	6J8	Rest	8-10	2-5	-	-	-	8.7	960	0.35±0.05	490-539	10-30	80

The shunt mangnin also is called Manganin 43, it is similar to our 6J13. The 6J12 is same to Manganin 47.

The available diameter for the CuMn alloy wire is from 0.05mm to 8mm.
