Things to Know About Recycling Carbide Sludge
November 06, 2018

Metal scrap is highly valuable, and can come from a number of things that we have at home. This includes steels, alloys made from tungsten, tungsten carbide sludge, hard scrap and many more. We at Alnor Industries specialize in the recycling of nickel alloys, tantalum, cobalt and molybdenum scrap within Mississauga and the GTA.


Be it high-speed steel or carbide sludge, we at Alnor Industries can help recycle all of your metal scrap!


We base the value of scrap metals on global prices. We deal directly with processors who can recycle and reform metal scrap and raw materials into useable products. With years of experience recycling tungsten scrap and carbide sludge, as well as other kinds of electronic waste, we take pride in helping you recycle your e-waste while doing our part to help conserve the environment.


Carbide sludge is also known as a grinding swarf. It is the result of tungsten carbide that was ground and contains moisture and oil. This is derived from any tool manufacturer, scrap dealer, and anyone that grinds carbide. Carbide sludge is essentially made up of 70% tungsten and 10% cobalt. We particularly base this price on the amount of tungsten recovered.


Here some things that you should know about recycling carbide sludge:


  • Value of Tungsten Carbide Sludge – Carbide sludge is highly valuable to the tungsten carbide tooling industry. Tungsten swarf, as it is sometimes called, can actually occur in low tungsten (20%) or high tungsten (90%) forms.
  • Nature of Tungsten Carbide Sludge – With a roughness that is double than that of steel, tungsten carbide sludge actually comes from different grades of tungsten. These various grades can actually all be utilized in the recycling industry for tungsten carbide. Carbide sludge is useful in that it can be reused for various applications in different industries.
  • Purpose of Recycling – After the quantity and percentage of tungsten carbide is determined, the coolant, excess oil and unnecessary particles will then be separated from the sludge. After analyzing these various components, a payment will be made! Our sludge recycling tasks have the goal of turning this sludge into alloy bearing materials.


The scrap metal recycling industry is a great way of helping recycling scrap metal for the benefit of the owner as well as the environment from the damaging effects of pollution. Tungsten carbide sludge is one of the most useful raw materials that is produced from various manufacturing processes. If you’re looking to recycle carbide sludge, we at Alnor Industries can provide you with the service you need.
