Tungsten Carbide Product Information - H.C. Starck
Almost all tungsten containing residues or used hard metal components, such as drills and milling cutters, can be reworked into new, high quality tungsten carbide. A sophisticated recycling process guarantees that the product made from secondary raw materials is not inferior in any way to that made from primary raw materials.
Tungsten Carbide Coating | Tungsten Carbide | HVOF Thermal ...
Tungsten Carbide Coating Benefits. The HVOF tungsten carbide thermal spray process produces tremendous amounts of kinetic energy into the powder particles. When these highly energetic particles strike the substrate, their velocity drops to zero and they absorb their kinetic energy, which causes them to bond instantly to the workpiece.

Tungsten processing | Britannica
Tungsten carbide (WC) Tungsten carbides are divided into two categories. The first is the cemented tungsten carbides, also called hard metals, which are essentially WC produced from sintering a mixture of carbon black and hydrogen-reduced tungsten powder at 1,500° C (2,700° F). These are cemented using a cobalt or nickel binder, with or ...

How to Recycle Tungsten Carbide - 911metallurgist
Tungsten and cobalt are mined and milled to concentrates. The concentrates are refined commonly to the metal oxide which is then reduced to a pure metal powder. Tungsten powder is blended with carbon (lampblack) and converted to tungsten carbide usually in induction furnaces at temperatures from 1300 to 1500° C (2400 to 2800° F).
What is Tungsten? What are Tungsten Carbide Rings? What is ...
In an extraordinary process, Tungsten and Carbide powders are forged together at over 2,800 degrees Fahrenheit to form rings that are virtually indestructible and scratch proof. Then they are polished with a diamond compound, resulting in a polish and shine that will last forever. Tungsten rings offer the perfect combination of unbelievable ...
How is Tungsten Carbide Formed? | Chronicle
Aug 13, 2015 · Tungsten has the highest melting point of all metals, at 3410 o C (6170 o F). In order to create parts made from tungsten or tungsten alloys like tungsten carbide, the typical process of melting and blending of the metal and alloying elements is cost prohibitive.
