Kanthal A-1 is a ferritic iron-chromium-aluminium alloy (FeCrAl alloy) rated for use at temperatures up to 1400°C (2550°F). The alloy has high resistivity and great oxidation resistance. It is typically used in furnace applications, such as electrical heating elements in high-temperature furnaces for heat treatment, glass, steel, ceramics, and electronics industries.

Features

  • Computerized spooling by weight.
  • Clean production environment houses spooling process.
  • Proudly Made in the U.S.A. ZERO wire imports policy.
  • Perfectly tensioned. Zero elongation, scratches, or other flaws.
  • ZERO contaminants. Hands-off feeding eliminates skin salts & oils.

Resistance

The more wire you have, the greater the resistance. The following factors affect resistance.

Diameter: The thinner the wire (higher gauge number), the higher the resistance per foot. The thicker the wire (lower gauge number), the lower the resistance.

Length: The longer the wire, the higher the overall resistance. The shorter the wire, the lower the overall resistance.

Temperature: The more heat the wire generates, the more resistance it will create.

Current: Determine the current (amperage) you need to heat your wire.
