Nichrome wire is a type of resistance wire made from an alloy of nickel, chromium, and sometimes iron. It has high electrical resistance and high melting point, which makes it suitable for use in electrical heating devices such as toasters, hair dryers, and heating elements for industrial furnaces.
Nichrome wire is also used in cutting applications, such as in CNC foam 3D equipment and CNC foam cutting machine. In these applications, the wire is heated to a high temperature using an electrical current, and then used to cut through materials such as foam, plastic, and even some metals. The heat generated by the wire melts or vaporizes the material it is cutting, allowing it to easily slice through.
In summary, nichrome wire is a type of wire that is used for cutting and heating applications due to its high resistance and melting point.
