Tungsten carbide chippings - availability?

[dyno-tron]

Just to confirm these are not carbide, they are tungsten alloy, but yes they will certainly be more durable than steel.

I do have a handful of dead carbide inserts as well as a some obsolete inserts I have no use for, want them? Could smash then up for your chippings?

Also got a jam jar full of funny little Insert things with carbide brazed on the end of it's worth the effort removing the carbide?

I'll get photos of all this actually if you are interested?

Sounds good - yes please, I'm always on the lookout for scrap metal stuff. I avoid buying new metal as a lot of the stuff I sell is for good causes ( e.g. our local primary school PTA) and the selling price is always limiting factor - no one wants to spend lots of money at the school fayre!!

The drilling rigs use a braze on coating called Nutty Crunch (I have no idea what the product name is) which may be what you’re after? It’s a brazing rod with tungsten chunks in it and a flux coating. Needs to go on hot. Use a cutting torch to braze it on.

That's similar to the rod hotponyshoes mentioned (for adding grip to horse shoes) unfortunately It's not cheap, about £20 per stick !!

Ive never bought it. I assumed it was costly, but they/I used to get through boxes of it on the drill ship. I wasnt drill crew but used to get asked to braze the heads up which is how I know of it. Bit pricey for a school fete mind!!!

Some time back I'd made a load of wood stuff for the fayre, all proceeds to the school. A 12" fruit bowl I made out of idigbo (scrap from when we had a gate made) probably had about 3 hours work in it including sanding and final finishing with food grade waxes, had it on the stall for £15. It caught the eye of one of the posh mum's, she came back a few times to look at it, finally commenting "I like it but it's a bit pricey isn't it? ", "All proceeds to the school" I said. Just the blank would have cost about that much! She bought it anyway.

Yes please to the lot!! Let me know the postage cost.

 

[grim_d]

I'll bring them home and weigh them and I'll let you know.

Okeydoke, thanks!

Im looking for some Tungsten chips or bar (not carbide) if any spare I could buy. Id like about 500g - 1kg. Had a look on ebay, all I can find are tig electrodes.

 

[grim_d]

What's it for? I do have a few bits of tungsten heavy alloy left over but sacrificing them purely for chips doesn't appeal greatly.

1kg is quite a small peice of tungsten though!

It's a shame you didn't say sooner!

I'll check out what grim_d has sent me on Mon/Tue next week, I should be able to share some with you for just the cost of postage

Happy to pay for a small piece, Id guess 25- 30mm dia by 50mm long would be ideal. The density is what Im after to make a small hammer. If its chips then I'll make it hollow as a deadblow hammer.
Tungsten is 19.3g/cm,
carbide 15g,
Steel /brass or any other normal metal is under 9g

I made a small brass hammer already, doesnt have the weight it needs! Anything much bigger would be a pain.

Let me have a look and see what's there and if I've anything suitable for your needs, probably Monday before I'm back there however.

It's far far less dense in chips because of all the air, that big tub I sent to @dyno-tron didn't weigh nearly as much as the stock it came from despise being bigger in volume.
