We can often see the appearance of resistance products in our daily life. There are usually carbon film resistors, metal film resistors, metal oxide film resistors, etc. Currently, there are more and more alloy resistors on the market, and many people are not sure which materials are usually made of alloy resistors. The difference in resistance products made of different alloy materials is very large. Let's analyze the alloy resistance materials.

1. Copper-manganese alloy resistors produced from copper-manganese alloy materials
Copper-manganese alloy materials have been used in the early days to manufacture resistors. These alloy resistors are characterized by high sensitivity, fast response, good linearity, and small temperature coefficient of resistance. They are very suitable for making ultra-high pressure sensors.
 
2. Alloy resistance produced by Constantan alloy
Constantan alloy is a copper-nickel alloy composed of 55% copper and 45% nickel (Cu55Ni45). The properties of the constantan alloy are not easy to change with temperature and have high electrical resistivity. The resistance produced by the constantan wire has a low temperature coefficient of resistivity and a medium resistivity, and the general resistivity is 0.48 μΩ•m.
 
3. Alloy resistance produced by copper-nickel alloy
Alloy resistances produced from copper-nickel alloys can be used in many applications. These alloy resistors have high strength, corrosion resistance, hardness, electrical resistance and pyroelectricity, and reduce the temperature coefficient of resistivity. 

With the emergence of more alloy materials, there are more choices in the production of alloy resistors. These alloy resistors have long service life, stable resistance, low power deviation, high temperature resistance, and faster heating. The surfaces of them are also very bright and bright, and many electrical industry products are widely used in the electronics industry.
