The Crazy Wire Company
Want to build your own coils, then you need to look no further. We have you covered with these great options from The Crazy Wire Company. Choose from Kanthal Type Wire, Stainless Steel or Nickel-Chrome.
Kanthal Type Wire
We know that the KANTHAL A1 ™ brand name is regarded as a sign of quality. This KANTHAL A1 ™ resistance wire is sourced by The Crazy Wire Company from Sandvik in Sweden, who are the originators of the protected brand name KANTHAL A1 ™ wire.
What Is The Difference?
As well as stocking genuine KANTHAL A1™ resistance wire The Crazy Wire Company offer FeCrAl Alloy as a top quality alternative to KANTHAL A1™. FeCrAl Alloy is the metal type, so there is absolutely no difference in quality between KANTHAL A1™ and our own FeCrAl Alloy Wire.
About The Wire:
C = Min – 0% Max – 0.08%
Si = Min – 0% Max – 0.7%
Mn = Min – 0% Max – 0.4%
Cr = Min – 20.5% Max – 23.5%
Al = Nominal Comp – 5.8% – Min – 0% – Max – 0%
Fe = BalanceNi80 wires are soft and are easy to handle and cut
Stainless Steel Wire
SS316 Wire Spools Marked With Fuchsia Stickers For Differentiation
This wire is in our stocks for use for weaving mesh. SS316 grade is the industry standard grade of stainless steel for use in the marine, food and medical industries.
SS16 grade commonly features are food processing equipment, wine making, beer brewing, milk processing, kitchen benches, sinks, troughs, equipment and appliances, heat Exchangers, woven or welded screens for mining, quarrying & water filtration, threaded fasteners.

Ni80 Nickel/Chrome Wire
Nickel chrome 80/20 is commonly used as a heat treatment wire. In modern times it has found popularity in the vaping industry due to its high heat and electrical resistance.
80/20 nickel-chromium alloy is often used for wrought and cast parts for high-temperature applications, as it has better oxidation and hot corrosion resistance compared to cheaper iron-nickel-chromium alloys. This nickel-chromium alloy is highly suited to applications that are subject to oxidation.
