Nichrome& Kanthal

The two major types of resistance wire are Kanthal and Nichrome wire.
Kanthal is a ferritic iron-chromium-aluminum alloy that can be in high temperature applications. It is often used in large, industrial applications and chosen for its high resistivity and excellent oxidation resistance.
Nichrome is made from nickel-chromium alloys is generally only used in temperatures below 1250°C.
Nichrome has a slightly lower maximum operating temperature than Kanthal and operates best applications such as hair dryers, toasters, and kilns.
