Kanthal A-1 Wire, 30 Gauge .01 Resistance heating wire -100 ft. spool

Description

Genuine USA Made Kanthal A-1 Resistance Wire
Kanthal A-1 is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) with high resistivity and very good oxidation resistance. It is suitable for use at temperatures up to 1400°C (2550°F). Typical applications for Kanthal A-1 are electrical heating elements in high-temperature furnaces for heat treatment, ceramics, glass, steel, and electronics industries. The best atomizer wire available! 100 ft per spool. (May ship on 2 spools of 50')
