Talk:Kanthal (alloy)

Hello, someone wrote :Ordinary Kanthal has a melting point of 1200 °C. Sorry, this is something wrong. Kanthal alloys have a melting of appr. 1500°C. And I d'nt see a melt. point of 1200 °C in the referenced patent. -- 87.161.245.142 (talk) 15:46, 9 April 2008 (UTC)

Quote: "Kanthal wire forms a protective layer of aluminum oxide (alumina). [1] Aluminium oxide is an electrical insulator but has a relatively high thermal conductivity; special techniques may be required to make good electrical connections."

Need more information or a links about the "special techniques ... to make good electrical connections." Alex65 box (talk) 15:57, 22 July 2010 (UTC)

Percentages don't add up
If there is 30% each of iron and chrome and 7.5% aluminium then there is 32.5% of something else that isn't listed - anyone know either the correct proportions or the missing ingredient? Timmydog (talk) 10:31, 23 December 2017 (UTC)
 * There's a lot more iron than that (and that isn't what the article says). Kanthal AF (typical kiln heating element, I have a roll here) says iron 72%, chrome 22%, aluminium 6%. Andy Dingley (talk) 12:29, 23 December 2017 (UTC)
