C10Ni90 Nickel chromium alloy wire
Cr10Ni90 is a nickel-chromium alloy, also known as resistance alloy, with high resistance and high melting point. This alloy is mainly composed of 10% chromium and 90% nickel, and is usually expressed in the chemical formula as Cr10Ni90.
Its main use is as a resistance wire, which is widely used in electric heaters, electric furnaces, heaters, hot air blowers, electric water heaters, water heaters, temperature sensors and other electric heating equipment. Due to the high resistance and thermal stability of Cr10Ni90 alloy, it is able to generate sufficient heat in high temperature environments, making it an ideal electric heating element.
