carbide tools sales company. Carbide is the most widely used class of high speed machining (HSM) tool materials, which are produced by powder metallurgy processes, consisting of hard carbides (usually tungsten carbide WC) particles and softer metal binders composition.
Description: Star SU offers a wide variety of tungsten carbide blanks and preforms from H.B. Carbide. Using only the highest quality raw materials and employing state-of-the-art, computer controlled vacuum furnaces and vacuum Sinter-Hipping furnaces, these cemented carbide preforms can be
Due to the extremely high melting point of tungsten carbide (≈2785 °C ), fully dense tungsten carbide bodies are extremely difficult to produce without the inclusion of an additive that will melt at far lower temperatures in order to cement the WC particles together to form a dense body. This process is known as sintering or, more
Core fabrication is one of the key technologies of glass moulding process used in micro optical component manufacturing. However, when the cavity size is very small and an array-type cavity is needed, a conventional diamond turning process cannot be employed. In this study, a novel core fabrication
When the goal for a part is the longest possible lifecycle and highest performance while operating under high temperatures, in a corrosive environment, and with the potential for extreme wear, then powder metal manufacturing can offer a very cost-effective option.
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.
To ground down same thicknesses for zirconia takes almost 10x more time than alumina and consume more diamond tools. Also, since the thermal shock resistance for zirconia is poor and requires higher sintering temperature, the sintering process also cost more than alumina. Applications: alumina vs zirconia
It will be discussed that the key challenge to the production of bulk nanocrystalline cemented tungsten carbide materials is to control the rapid grain growth during the early stage of sintering. The current understanding on the mechanical properties of cemented tungsten carbide made from nanoscaled WC-Co powders will also reviewed.
