Resistance Wire?is a specialized type of wire designed to resist the flow of electric current, converting electrical energy into heat. This wire is typically used in various heating applications?due to its high electrical resistance?and ability to generate heat when an electric current passes through it. Commonly used in heating elements?for industrial, commercial, and residential purposes, resistance wire is an essential component in products like electric heaters, toasters, ovens, and industrial furnaces.

What is Resistance Wire?

Resistance wire?is typically made from alloy materials?that possess high resistivity, such as nichrome?(nickel-chromium alloy), kanthal?(iron-chromium-aluminum alloy), or copper-nickel alloys. The wire’s resistance to electrical flow causes it to heat up, which is the fundamental principle behind many heating elements?in electrical appliances and industrial machinery. The wire is carefully engineered to handle specific amounts of current and heat generation, making it an ideal choice for creating reliable and durable heating elements.
