Product Overview


Product Description

The resistivity of our alloy material ranges from 0.13μΩ·m to 1.35μΩ·m, which enriches the resistivity gradient of the alloy, and customers can choose from a wide range of resistivity. Manganese copper precision resistance alloy has the characteristics of low resistance temperature coefficient and low thermoelectric emf rate against copper. It is suitable for making all kinds of standard resistors, shunt and fixed chip resistors. The material can be customized according to customer requirements.
