Scrap Carbide Prices per Pound + Other Important Carbide Recycling Info

Pile of scrap carbide pieces

Selling scrap metal allows you to earn extra income while recycling valuable materials.

Carbide, in all its various forms, can be highly valuable. You may even have scrap carbide already in your home, waiting to be turned in for cash.

Below, we detail the scrap carbide prices per pound, as well as everything else you need to know prior to making the sale.

Where to Find Scrap Carbide

Tungsten carbide is primarily used in cutting and drilling equipment in industrial applications.

Some of the most common sources of recyclable carbide are end mills and drill bits left over from machining projects.

In fact, lots of machining leftovers, even non-solid leftovers, might have a high enough carbide content to be valuable.

While larger machine shops are very aware of the value of their scrap carbide and will likely either resell or recycle it, you may be able to pick up leftover industrial carbide scraps – particularly carbide inserts – from a friend with a home machining shop or from the owner of a tire-changing establishment, for instance.

Carbide can also be found in household products. You might find carbide in sporting equipment (snowmobile spikes, for example), knife sharpeners, light bulb filaments, high heat coils, jewelry (men’s wedding rings, for example), fishing equipment (especially lures), hiking equipment (the tips of a trekking pole, for example), tire studs, working components of ballpoint pens, and razor blades.

Carbide is unusually heavy, so if the metal in these types of objects seems heavy for its size, it could be carbide.

You can try the magnet test (explained later) or a variety of other identification tests to get a better idea of whether your scrap metal is carbide.

Types of Carbide

Carbide generally comes in three types: solids, sludge, and powder. All three types are recyclable.

Solids include any solid pieces of carbide left over from machining or found in household items. Sludge is a liquid byproduct of various machining processes. Carbide powder might be left over from machining; the metal can be purchased in this form as well.

1. Solids

  • Examples: Drill bits, inserts, taps, router bits, end mills, cutoffs, round stock, dies, punches, reamers, etc.
  • Selling solids: Any recycler that takes carbide will take solids.
  • Pricing: If your solids are pure carbide, they will sell for the current price of carbide. Be aware that not all solids are made from carbide alone; if only part of a solid needed to be very durable, for instance, then it may be that that part is carbide and the rest is a less valuable metal like high-speed steel. Some drill bits contain carbide only in the tip, for example. Use the identification tests mentioned below to get an idea of what the carbide content of your solid scrap is.

2. Grinding Sludge

  • Examples: Sludge is the byproduct produced from grinding, cutting, shaping, and manufacturing carbide tooling, inserts, and other carbide items.
  • Selling sludge: Sludge is recyclable, but not all recyclers have the facilities to process and recycle sludge. Be sure to call and confirm that your recycler accepts sludge before you make a trip.
  • Pricing: The value of sludge depends on what percentage of it is carbide and what percentage are contaminants. The heavier your sludge, the higher its carbide content. As benchmarks, a 40-pound gallon of sludge probably has high carbide content. A 24-pound gallon may or may not have enough carbide to be recycled, it will depend on moisture and contaminants. A 12-pound gallon is probably not recyclable. The recycler will only be able to confirm the carbide content and final price after an analysis is done.

3. Powder

  • Examples: Carbide powder may be left over from machining processes with carbide parts.
  • Selling powder: Powder is recyclable, but not all recyclers have the facilities to process and recycle it. Be sure to call and confirm that your recycler accepts powder before you make a trip. Powder is easier to separate than sludge, so recyclers can buy it even when the percentage of tungsten is as low as 20%.
  • Pricing: The value of scrap carbide powder depends on the percentage of contaminants. As with sludge, the heavier your powder, the higher the carbide content. Tungsten powder is used in processes like thermal spray for hardfacing and other processes; so if your scrap comes from a process that began with tungsten powder, it will have a higher tungsten content and thus be more valuable.

How to Identify Carbide

There are two types of solid carbide scraps: clean and dirty. Clean scraps are solids, such as drill bits. Dirty scraps have braze alloy in them, which is a type of solder that appears white-gold. These dirty scraps, such as saw tips, are still valuable. You can identify carbide by weight or by using the tests described below.

  • Weight: Carbide can be identified by weight because it is very heavy; two tablespoons weigh over a pound.
  • Spark Test: Carbide is usually found in end mills, inserts, or saw tips. When put on a grinding wheel, carbide will make sparks that are dark reddish-orange, short, and dim rather than white firework-like sparks.
  • Magnet Test: True tungsten has little attraction to a magnet; tungsten carbide will not stick to a magnet and will pull away easily. If the magnet sticks, the material is probably steel.
  • Scratch Test: Scratch the material with a known piece of carbide. If it’s steel, you’ll immediately notice scratches. If it’s carbide, you’ll see little to no markings.
  • Rust Test: Steel will rust; carbide won’t. If what you’ve got is rusty, it’s definitely not carbide.

End mills, reamers, boring bars, and round toolings are often made from carbide but are sometimes made from steel.

Inserts are almost always made from carbide, and steel inserts are easily separated with a weight test.

Spade bits are almost always steel, but are occasionally made of carbide.

A magnet test will easily reveal which is carbide. If you find that some of your scraps are not carbide, knowing the price of scrap metal recycling per pound will help you determine whether recycling them is worth your time.

Watch the following video to see examples of the weight, magnet, scratch and rust tests. You’ll also learn more about clean and dirty scraps and about how the quality of the carbide affects its value.


The quality of “soft scrap” carbide (the sludge or powder produced after grinding a piece of carbide) can only be determined in a laboratory, but you can estimate the quality yourself by its weight.

How Much Is Scrap Carbide Worth?

The price of scrap carbide correlates to the price of tungsten; scrap yards usually pay about two-fifths of the current price of tungsten for scrap carbide.

Like most commodities, tungsten prices (and therefore the base price of scrap carbide) have varied significantly over the past ten years. Always call your scrap yard to confirm the current price, which will vary based on the carbide’s form (solid, sludge, powder, or grindings) and quality.

Be sure to inquire with the recycler to confirm current prices and check whether they can process a non-solid form of carbide.

The iScrapApp is a great tool for checking up-to-date carbide prices; you can input your location to find recyclers near you, check their prices, and get the contact information you need.

Some recyclers have online quote estimators, and you can use these to request and compare prices. There will likely be a bit of a delay, but these prices will be highly accurate because the recycler will check prices and reply individually to your specific inquiry (generally by email).

  • Cutting Edge Tool Supply has an online quote request form and lists estimated current prices.
  • Kennametal has an online quote request form and also accepts scrap carbide from Canada and the UK.
  • Machine Tool Recyclers can give quotes via phone; you can contact them at (630) 964-5030.
  • Lots of people sell scrap carbide on eBay; take a look at their pricing for ideas.

How and Where Can You Sell Scrap Carbide?

You can sell scrap carbide at a local scrap metal yard or to a recycler that buys via mail.

For local scrap metal yards, try the iScrapApp to get started. It will give you contact information for local scrap yards and national average prices as well.

The following list is a sampling of buyers who will accept carbide by mail. Most scrap carbide purchases by mail are for large quantities, but buyers will often accept small quantities as well.

Depending on current scrap carbide prices, however, shipping costs may make selling by mail unprofitable.

    Current price per pound of carbide?

      Hi Vincent,

      The price of scrap carbide is hard to estimate, and your best bet for an accurate price is to contact the scrap yards near you to see what they’re currently paying. The price depends on production, and a lot of the tungsten in the US is imported from China. If you’re curious about the world’s supply of tungsten, this USGS commodity summary on tungsten is a good reference. To estimate the current price, we can look at prices set by major minerals companies like Almonty, who entered into 1-year price contracts for tungsten in 2017, and set the price at $210 per MTU. An MTU is 10kg, so that puts tungsten at $21 per kilo, or $9.50 per pound. Carbide correlates to the tungsten price, and scrap carbide is usually around 2/5ths the price of tungsten. So, your scrap carbide could be around $3.80 per pound. But, this is just an estimate.
