Can a car's heating wire still be used if it's slightly broken?

No. Here is some relevant information about heating wires: 1. Main uses: Industrial heating equipment and household heating appliances in metallurgical machinery, medical, chemical, ceramic, electronic, electrical, and glass industries. 2. Diameter and thickness: The diameter and thickness of a heating wire are parameters related to its maximum operating temperature. The larger the diameter of the heating wire, the easier it is to overcome deformation issues at high temperatures, thereby extending its service life. When operating below the maximum temperature, the diameter of the heating wire should not be less than 3mm, and the thickness of the flat strip should not be less than 2mm. The service life of a heating wire is also largely related to its diameter and thickness. When used in high-temperature environments, a protective oxide film forms on the surface of the heating wire. After a period, this oxide film ages, creating a continuous cycle of formation and destruction. This process represents the continuous consumption of internal elements in the heating wire. Heating wires with larger diameters and thicknesses contain more elements, thus having a longer service life.
