Nickel-chromium 90 (Ni90) strip from Chinese suppliers
This type of alloy strip exhibits a combination of high electrical resistivity, low temperature coefficient of resistance, and excellent magnetic properties. Nickel-iron alloy strips are commonly used in various applications, including electrical and electronic components, sensors, magnetic shielding, and transformer cores. They are particularly valued for their ability to provide precise control over magnetic properties and their stability over a wide range of temperatures.
