Pugaboo Posted March 15, 2016 Report Share Posted March 15, 2016 I've been hunting for new wires for my bead racks. I decided to go with Kanthal A-1 wire since the manufacturer says it can fire to 2550. BUT.... Some sites state Kanthal A-1 wire only fires to 2055. I even called and they checked and their supplier states it only goes to 2055. So is there more than one type of Kanthal A-1 wire and how do I know which is which, as in is there an additional code or something I can look for or ask them for? Oh and on top of that I need 9 gauge Kanthal A-1 wire. I tried googling but those stupid e-cigs apparently use Kanthal A-1 wire but in a really small gauge and most of what comes up is about that.

bciskepottery Posted March 15, 2016 Report Share Posted March 15, 2016 I will venture that different gauges have different temperature tolerances. http://www.kanthal.com/en/products/materials-in-wire-and-strip-form/wire/resistance-heating-wire-and-resistance-wire/ Link to comment Share on other sites More sharing options...
Mark C. Posted March 17, 2016 Report Share Posted March 17, 2016 I would agree the thicker the wire the better it holds up. Its gauge thickness that will help make it stiff at temperature Link to comment Share on other sites More sharing options...
Pugaboo Posted March 17, 2016 Author Report Share Posted March 17, 2016 I should clarify, I need 9 gauge Kanthal A-1 wire, know this is the gauge I need so thinner gauge information doesn't help. looked on the manufactures site and is says this gauge goes to 2550 F. I found 9 gauge Kanthal A-1 on one site but they state it only goes to 2055F, I called and asked if it was a typo (numbers being the same just in different order and all that) and they checked their supplier who confirmed it only went to 2055. So is there another way of knowing the 9 gauge Kanthal wire I am looking at goes to 2550 or not? There has to be some way manufacturers can tell them apart, an additional code or something? Thanks for your help on this, it's very confusing to me. T Link to comment Share on other sites More sharing options...
neilestrick Posted March 18, 2016 Report Share Posted March 18, 2016 According to the Kanthal site, they list A-1 as having a max continuous operating temperature of 2550F, with no specs on thickness. If A-1, which has been the industry standard for a long time, could only work up to 2055F, it would be melting in the element grooves at cone 6.

Pugaboo Posted March 18, 2016 Author Report Share Posted March 18, 2016 That's what I thought. So the company I found must not be selling actual Kanthal a-1 wire but a knock off maybe? Anyhow the search continues for a supplier. Found lots selling down to gauge 12 but having trouble finding 9 gauge. Does anyone know of a website that sells Kanthal A-1 wire in 9 gauge that they would like to share? T Link to comment Share on other sites More sharing options...
oldlady Posted March 18, 2016 Report Share Posted March 18, 2016 terry, the Kanthal website has a "contact us" , why not do that and ask where it can be bought? Link to comment Share on other sites More sharing options...
Pugaboo Posted March 18, 2016 Author Report Share Posted March 18, 2016 Excellent idea oldlady! Don't know why I didn't think of it, thank you and I will contact them. T Link to comment Share on other sites More sharing options...
neilestrick Posted March 18, 2016 Report Share Posted March 18, 2016 I have found a couple of sites that sell replacement bars for bead racks, in 9ga size. Bailey says theirs are rated for cone 6. I don't think you'll find any that are rated for hotter than that, because they'll just bend at higher temps unless they're 1/2" thick. Just because the rated temp of A-1 is 2550, that doesn't mean it can support suspended beads at that temp. Link to comment Share on other sites More sharing options...
glazenerd Posted March 18, 2016 Report Share Posted March 18, 2016 or you could just buy the replacement wire specifically made for bead racks-- already precut to length. http://www.axner.com/nichrome-wire.aspx Nerd Link to comment Share on other sites More sharing options...
Pugaboo Posted March 18, 2016 Author Report Share Posted March 18, 2016 The issue I have with buying more bead rack precut wires is that the wires turn green over time and this green can at times come off on a piece. Right now when this happens I have a small sanding bit for my Dremel that I can carefully clean out the inside of the hole with. But it's sanding glaze and I try to avoid doing that even with a mask on. I have some Kanthal a-1 gauge 12 wire I use for earrings and it has not turned green. Hence my search. But if needed I will just get some more precut bead rack wires. T Link to comment Share on other sites More sharing options...
