Constantan ọla kọpa Nickel 40 Waya / Flat Waya maka ọkụ eletrik
Constantan Strip (CuNi44Mn) ọla kọpa Nickel Electric Resistance Heating Ribbon
Nkọwa Waya Constantan
Alloy na-eguzogide ọgwụ nwere oke resistivity na obere okpomọkụ coefficent nke nguzogide na ewepụghị eguzogide / okpomọkụ usoro n'elu a wider nso karịa "manganins". CuNi44 Alloy waya na-egosikwa mma nguzogide corrosion karịa nwoke ganins. A na-amachibido ojiji ya na sekit ac. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy Waya bụkwa ihe na-adịghị mma nke ụdị J thermocouple na Iron bụ ihe dị mma; A na-eji ụdị J thermocouples na ngwa ọgwụgwọ okpomọkụ. Ọzọkwa, ọ bụ ihe na-adịghị mma nke ụdị T thermocouple na OFHC ọla kọpa na nti; Ụdị T thermocouples na-eji okpomọkụ cryogenic.
