The Expansion Alloy series, comprising various Copper-Nickel (CuNi) grades, is engineered for applications requiring precise thermal and electrical properties. These alloys exhibit low electrical resistivity, excellent thermal stability, and high corrosion resistance, making them ideal for use in electrical heating elements, resistors, thermocouples, and precision instruments.
