6J12/6J12P/6J12X Precision Resistance Wire Nickel-Chromium Alloy for Electrical Resistance

The 6J12 alloy wire is a manganin-type material composed primarily of copper (Cu), nickel (Ni), and manganese (Mn). It is widely used in precision electrical applications due to its excellent resistance stability and low temperature coefficient of resistance (TCR).

6J12’s long-term stability, high durability, and reliable performance in varying environments make it a cost-effective choice for many industries. Proper annealing can further enhance its performance.

In summary, 6J12 combines high electrical precision with thermal and mechanical resilience, making it indispensable in precision measurement and low-EMF applications.
