How To Sell Scrap Carbide, Tungsten Carbide, Cemented Carbide

  • Sharebar
Carbide is commonly regarded as the most valuable type of scrap a person can happen upon. I, for one, always get the biggest kick out of getting even a little WC! The hardest part is discovering where to find scrap carbide!

What is Tungsten Carbide?

Carbide will often be coated in a titanium compound,
like those pictured above.

Tungsten carbide is one of the strongest material used by man. It is almost as hard as diamonds. I don’t think it is worth going into specifics, so lets just say… IT IS STRONG!

Scrap tungsten carbide, aka scrap carbide, is commonly found in mill tools, as carbide tools can last decades with just a few sharpenings.

Tungsten Carbide, is also very heavy! VERY HEAVY! It is twice as heavy as steel, almost as heavy as gold. It doesn’t take very much to yield a few pounds, so serious money can pile up quickly!


What is the difference between Carbide and Tungsten Carbide?

Let me clarify some of the confusion! There are actually 3 technical terms often thrown around by scrappers. In a scrap yard, they all basically mean the same thing: tungsten carbide impregnated metal.

  • Tungsten Carbide: This is, in fact, *technically* NOT a metal. (…What!?) It is a ceramic compound of Tungsten (W) and Carbon (C), hence the chemical formula WC. Tungsten Carbide is actually very rarely used in plane ceramic form, if ever. Tungsten Carbide is also used in compounds of two parts tungsten, aka W2C. This however is actually tungsten semicarbide.
  • Cemented Carbide: THIS is what most of us think of when we hear “carbide.” It is actually between 5% and 25% Cobalt by weight. To explain why, think of cemented carbide like Jell-O with a lot of fruit. The cobalt acts like the Jell-O, and the tungsten carbide is super-dense, ass-kicking fruit that makes the jello much denser, and much stronger. Obviously, the Jell-O with more fruit is stronger, and the cemented carbide with lots of WC is very strong.
  • Carbide: This is a material scientist’s word for “a compound of carbon with something more electro-negative.” So, technically, its not specific enough, and could be referring to any carbide compound. That’s ok, because if your scrapping, we’ll all know that you actually mean cemented carbide.

This small spark
signals value.


How to Identify Carbide, aka The Spark Test:

A very simple way to identify carbide, is to spark test it. Carbide has a spark test which yields a VERY dark, red, short spark. This is different from HSS (high speed steel) which will often have a longer, whiter spark, plus a few forks.

Please remember, it is very dense. So if you have a similarly sized piece of steel, carbide should weigh about twice as much as the steel.

That’s fine and dandy, but where do I sell it?

Of course, everybody’s scrap yard will buy scrap carbide. It’s just a wonderful thing to get! It doesn’t take up much space at all, and can be sold in small quantities easily. My scrap yard will only pay me between about $5 per pound of carbide, but the truth is that YOU CAN SELL IT ON EBAY or to other larger, carbide-specific, scrap yards for $10 per pound!!!!

Remember, the value of things on eBay ultimately have some fees taken out, but if you are not getting paid at least $9 dollars a pound at your local yard, SELL IT ON EBAY! You will usually make out like a bandit.

Good Luck Scrapping!

Awesome! So where can I harvest tungsten carbide? I see some drill bits up there, but can't ID those other bits you've got pictured.

In general, you find it in the form of tools: reamers, drills, inserts, tips saw teeth, ect. What you see in the picture is a an assortment of all of the above, especially lathe tools.

Love your site big time. Learning everyday. As far as the carbide is concerned…is the metal holding the copper wire in tv’s, rotisserie ovens, breadmakers, etc. actually carbide? They are very heavy. But, I’m just not sure what kind they are.
Thanks for the help.

Is tungsten carbide magnetic?

Reply

ScrapMetalJunkie April 29, 2012 at 6:06 am

carbide tools are all magnetic, but not as much as steel.

The compound tungston carbide (WC) on the other hand, is not magnetic. What makes carbide tools magnetic, as I tried to describe above, is the cobalt that is used in cemented carbide, aka “carbide”.

In popular, you discover it by means of tools: reamers, routines, places, guidelines saw tooth, ect. What you see in the image is a an variety of all of the above, especially lathe assets.

Great site, thanks for all of your time and effort. I have read much, as well as learned some to boot. Maybe you have covered this, but how does one recover carbide tips from saws blades. Thank you in advance.

Ok so I work at the movie theatre, and it takes some pretty big bulbs to run the projectors. Now ive busted one of the bulbs before and theres like a dime size cone of metal. Its very dense for its size. I would like to identify the metal and see how much theyre worth. Cuz if we just throw these bulbs away, screw it ill just harvest the tungsten if thats what it is inside…

Reply

ScrapMetalJunkie December 3, 2012 at 7:34 am

I would save the metal cone piece! It makes sense that it would be tungsten! But tungsten and tungsten carbide are very different materials. I would suggest using starting off identifying the material by using The Magnet Test!

Anna April 4, 2013 at 5:46 pm

The cone shaped pieces (anodes) and the rod it is connected to are Tungsten. The braided cord is copper. The round piece that the rod is connected to is a mix. The large anode is about 1/2 lb so it adds up fast. If you smack the rod with a hammer (be careful of the glass insulation) it will break away from the round piece. I’m sure you know but make sure to properly explode the bulb before you go smacking on it. Tungsten is used because it is the only metal that can hold up to the heat that a xenon gas(highly explosive) filled bulb generates.

I have a few pieces of material that is used for vibration dampening. I believe it is Tungsten. It is not magnetic and has very little spark(red) when grinding. It is at least twice as heavy as steel. I checked online for prices, but only see prices for tungsten carbide. What should I expect for this non-magnetic tungsten?(presuming that’s what it is)

Hi, I have a load of used Tungsten Carbide Burrs, would it be worthwhile cutting the steel stems off or not? Also, i live in UK so would it be worth shipping to USA if i sell on the International Ebay? Or would selling on UK’s Ebay be better?
Thanks in advance.

do you still have the WC burrs? if so please send your best offer on CIf Haldia with actual photos.

Jason July 11, 2013 at 7:54 pm

I just sold some inserts and end mills. The end mills I did the grinding test and the spark was dense. When the buyer received the scrap he contacted me and said the end mills were not carbide. What do you Suggest I do about this situation.

I am selling tungsten carbide for a many years in one company in Germany.
Now they reduce me the price becose some part of materials is not clean.
They say that is some Morgan rolls?? I never hear abouth that since a work with this material.
Can you tell me is this true or they just want to buy from me for a less price?

Please e mail me! Thank you
