Electrical Resistance Alloy
Via using the inherent resistance of materials, the alloy is made into different of functional elements. It mainly contains Heating alloy, Precision resistance alloy, Strain resistance alloy and Thermistor alloy. With the development of the computer, missile, atomic energy and space navigation and other most advanced tech, it needs us to create better electronic instruments and electrical measuring instruments, and the precision resistance alloy is the key. At the same time, it pushes the scientists to follow the trend and create better precision resistance alloys.
Since now, the alloys which can meet such requirements are not too much. Usually it has transition metals, nobel metals and rare metals, such as Cu-Mn, Ag-Mn, Au-Cr, Cu-Ni, Ni-Cr, Fe-Cr-Al and others.
Electrical resistance alloy is mainly used in precision resistor, rheostat, heater. Resistance alloy for precision resistors has low working temperature, usually used in room temperature, like manganese copper and nichrome alloy; Resistance alloy for rheostat working temperature usually can’t be over 500℃, like cupro nickel and konstant; Resistance alloy for heater working temperature can be 1400℃, like heating alloy, precision resistance alloy, strain resistance alloy and thermistor alloy.
