Product Description

Manganese bronze alloy wire (BMn3-12)
The marked characteristics of manganese copper alloy is a very small temperature coefficient of resistance, low identical electromotive force, and has the special excellent resistance stability.In the electrical and instrument measuring technology as well as the benchmark unit with a resistor is widely used.Manganese copper alloy has good welding performance and machining performance, can form the fine silk, rolling piece, foil, but poor corrosion resistance and oxidation resistance.
