6J12/6J12P/6J12X Resistance Wire Copper Manganese Nickel OEM For Heating System
The 6J12 alloy wire is a manganin-type material composed primarily of copper (Cu), nickel (Ni), and manganese (Mn). It is specifically designed for high-precision applications requiring stable electrical resistance, low thermal electromotive force (EMF), and minimal temperature coefficient of resistance (TCR).
The 6J12 alloy wire offers long-term stability, high durability, and consistent electrical performance in varying environmental conditions. It is also cost-effective for high-precision applications, making it a popular choice in scientific and industrial fields.
In summary, 6J12 combines high resistivity, low TCR, and corrosion resistance, making it indispensable in precision electrical and temperature-sensitive applications.
