Product info
Product name: Iron nickel expansion alloy wire
Other names: nickel iron alloy wire; nickel alloy welding wire
ApplicationRange
The products are broadly used as lead and structural materials in electronic tube, transistor and integrated circuit.Within certain range of temperatures, nickel iron expansion alloys approach the coefficient of glass, ceramics, and other similar in-sealing materials, to achieve matched sealing; therefore, nickel iron expansion alloys are also called seal alloys.
