HOW IS IT MADE?
Described as powder-metallurgy, the manufacturing process begins with a mix of fine tungsten and cobalt powders. Carbide wear, impact, and corrosion properties can be adjusted by varying the tungsten particle size, binder, or adding additional alloying agents.
Next the powder is compacted in a die to form a specific size and shape. These are called blanks. During this process, the blanks are the consistency of dense chalk, but are still soft and can be machined. Rectangles, cylinders, and round bars are common shapes pressed in these dies.
Using pressure and heat, the blank is processed in a high-temperature sintering furnace. After this step, the blank has become cemented Tungsten Carbide, and now has the high hardness and wear-resistant characteristics.
MIXED + PRESSED + SINTERED =
After the sintering process, carbide pieces are ready to be installed in high wear and impact situations! Carbide can be brazed, glued, or mechanically held in place to extend part wear life.
Repeated high energy impacts can make steel parts deteriorate more rapidly. Carbide has high impact strength and can resist wear and impact applications for far longer than ceramic or steel. This results in fewer repairs and replacement parts and lower operating cost.
Carbide hardness can be almost as hard as diamond and harder than tool steel. High hardness, results in greater wear resistance in abrasive applications. Carbide wear parts last longer.

HELPING PARTS PERFORM
Wear, impact, corrosion, and heat all affect the life and efficiency of wear parts. Carbide has many features that help parts perform more effectively by resisting wear and extending work life.
Carbide can perform reliably at temperatures where other materials would begin to soften. As steel heats up, it begins to anneal and lose hardness, thus decreasing wear resistance. Tungsten does not anneal and can be used in environments with temperatures approaching 1000 F.
Certain Carbide grades have special binders with nickel and chrome to increase corrosion resistance. Carbide grades can have corrosion resistance to handle environments with acetone, ethanol, gasoline, ammonia, most bases, weak acids, tap water, and other organic solvents.
Steel parts that experience extreme abrasion do not last as long as Carbide wear parts. In most instances, Carbide will last longer than typical steel by a factor of 25 to 1 or more!
We are pioneers in the engineering and application of solid Tungsten Carbide for industrial wear parts. We develop and produce wear solutions for industries such as material handling, ground-engaging wear parts, power generation, mining, mineral processing, oil and gas, railroad maintenance, and pet food production.
