Suppliers for SiC or MoSi2 elements?

Hey all,

I'm looking for suppliers for SiC or MoSi2 elements, trying to source a handful of elements for a gas -> electric retrofit for a small custom furnace - I've had an RFQ out with IsquaredR for a few weeks now but can't seem to get them to respond even after following up multiple times. Anybody know other outfits that sell silicon carbide or molybdenum disilicide heating elements?

From the glass world, I know Ryan Staub used to get some molys wholesale from a chinese vendor and re-sell them, but I'm not sure if he's kept up that sideline since moving out to Hawaii. Eddy & Cheyenne probably both keep some on the shelves for their electric furnaces, but this is for a custom furnace and I think I'm going to need some a bit shorter than their usual sizes.

I've been having surprisingly little luck chasing this, so if anybody knows of other sources I might be able to try, I'd certainly appreciate getting pointed in their direction

IR squared is probably the most expensive non responsive bunch you could choose to deal with.

Call duralite in Riverton Connecticut. Mark Jesson. I think he handles both. I have some Moly elements still here which I would indeed sell but moly's require fairly tight voltages to work properly. SiC, as I suspect you know are just straight up 240 V units. They are reactive with glass and they do change resistance as they age.

Getting them out of China has proved to be a major pai these days. It's why I quit bringing them in.

I've never encountered using both before in the same unit. I also have transformer here that I would sell. It's a conventional unit that would tap at 60V or 120V. It's ugly but it ought to work and would be cheap. I have quite a few 6/12 300/450's I also have clamps and braided straps

Not sure if they have any SiC things there but I second the mention of Duralite, and they seem to have some different sizes of Moly elements to choose from.

Delivery is a success until it isn't. Then the trouble starts. When I drop shipped elements to clients, I would insure with supposed insurance. If one element in six broke, they wanted to replace that element on the client's next order. That is not workable. Ultimately, between that, price increases and Chinese customs it was no longer a workable operation.

The one thing you do not want to do is to have to ship the same elements twice. I simply could not repackage elements to avoid breakage. I'm a very good packer.
I refer Duralite only because they handle a wider variety of elements. Cheyenne handles a narrow line.

FYI.... Duralite is selling off their stock of molys. I bought the last of their 450/450s a couple of weeks ago. Check availability because they are not going to buy from China anymore because of slow downs and breakage in shipping.
