CUNI30 ALLOY (CHEMISTRY - UNS 96400) WITH EXCELLENT CORROSION RESISTANCE IN SALT WATER AND STABLE MATERIAL PROPERTIES RANGING FROM 400 °C TO CRYOGENIC TEMPERATURES (-270°C)
CuNi30 is a type of resistance alloy that consists of a combination of copper and nickel. This binary alloy is known for its low-temperature coefficient of resistance, making it an ideal choice for various electrical components such as rheostats, shunts, and controllers. These components are typically designed for low-voltage applications and can operate at a maximum temperature of 300°C.
In addition to its use in electrical components, CuNi30 is also commonly used in low-temperature heating cables. For example, it can be found in automobile heating cushions and railway snow melting systems due to its excellent heat coefficient. This makes CuNi30 a versatile material that can be used in a variety of applications where low-temperature resistance and good heat conductivity are required.
C71580 copper-nickel is a type of copper-nickel alloy that is primarily used in the production of wrought products. This material is known for its excellent properties, especially when it is annealed. It is also known as CuNi30 in the EN chemical designation system and has the UNS number C71580.
Compared to other copper-nickel alloys, C71580 has a moderately high base cost. Additionally, it has a moderately high embodied energy and a moderately low electrical conductivity. However, despite these drawbacks, C71580 copper-nickel is still widely used in various industries.
The material properties of C71580 copper-nickel are compared to those of wrought copper-nickels, all copper alloys, and the entire database in the graph bars below. The bars represent the highest value in the relevant set, with a full bar indicating the highest value and a half-full bar indicating 50% of the highest value. This comparison provides valuable information for those who are considering using C71580 copper-nickel in their projects.
