Choosing Your Carbide Grade: A Guide | Modern Machine Shop
BB64 — PVD grades for nickel-based alloys. BB23 — CVD grades for milling cast iron. NN — Hardness Level: The last two digits, in most cases, reflect the hardness level of the different grades in a series. The number usually ranges from 05 to 45 according to the same system explained above about the grade charts.

Establishing tungsten carbides as active catalysts for CO2
Although tungsten and molybdenum carbides exhibit similar catalytic properties for hydrogenation reactions, tungsten carbide has not been thoroughly evaluated for CO 2 hydrogenation. We hypothesize that the extreme synthesis conditions necessary for carburizing tungsten can cause sintering, agglomeration, and carbon deposition, leading …
Tungsten Carbide
Cemented carbide, (also referred to as hard metal), is a material created by "cementing" very hard tungsten monocarbide (WC) grains in a binder matrix of tough cobalt metal, using the liquid phase sintering process. The combination of WC and metallic cobalt as a binder is a well-modified system not only relating to its properties, but also ...

Wear mechanism of tungsten carbide dies during wet drawing of …
Abstract. Wet drawing of brass coated steel wires, used for tyre reinforcement, is realised with tungsten carbide (WC) dies sintered with a cobalt binder. Die wear represents an important limitation to the production process and cost savings. Mechanical models of drawing are not sufficient to explain the phenomenon experimentally observed.

Tungsten Carbide – Nickel Chromium Self-Fluxing Powders
nThe sintered and crushed carbide hard phase used in Metco 36C, WOKA 7701 and WOKA 7703 results in tungsten carbide grains that are larger, more angular in shape and with higher apparent density. These carbides exhibit better distribution in the matrix with less dissolu-tion, resulting in reduced coating brittleness and a lower tendency to crack.
