S - Svavel/Sulphor; Tu - Tungsten; Ni - Nickel; Ph - Fosfor/Phosphor; V Co - Cobalt Increases strength and hardness, and permits quenching in higher Cr indicates Chrome in the alloy, Mo is for Molybdenum and Va is for Vanadium.

It is harder and more scratch resistant than titanium, gold, silver and platinum. While not as hard as tungsten, Cobalt Chrome does not easily break, shatter or chip.

Cobalt chrome is harder than precious metals like platinum, gold, and silver. As a result of its hardness, it will resist scratching and wear to a greater degree than its precious metal equivalents. As a frame of reference, cobalt rings come in around 7-8 on the Mohs hardness scale which is about the same as quartz or topaz but softer than tungsten or sapphire. Cobalt-chrome or cobalt-chromium (CoCr) is a metal alloy of cobalt and chromium.Cobalt-chrome has a very high specific strength and is commonly used in gas turbines, dental implants, and orthopedic implants.

While most tungsten carbide coatings are cobalt-based, Hardide has a tungsten carbide coating applied using low-temperature CVD that it says eliminates the cobalt binder traditionally used in sintered or sprayed tungsten carbide. Tungsten chromium carbide gives an Rc hardness

Cobalt rings and cobalt chrome wedding bands are a much lighter metal, with shades more akin to white gold than tungsten. Second, tungsten rings, due to their extreme hardness, have almost no malleability, whereas cobalt rings are very malleable. There are a lot of downsides that come along with a tungsten carbide ring that has cobalt in it. For one thing, while you wear it, the cobalt in the ring will react with the natural oils produced by your skin.

Chromium: 25-30% Molybdenum: 1% Tungsten: 2-15% Carbon: 0.25-3.3% Iron: 3% Silicone: 2% Manganese: 1% Cobalt: rest of the balance | often used for chrome replacement. Tungsten carbide cobalt chromium (WC Co Cr) and chrome carbide, CrC-NiCr are two of the most common powder materials used to replace chrome. HVOF was invented in the early 1980’s. It involves using a spray device pictured adjacent, into which the metal powder, oxygen and a fuel gas such as kerosene, Cobalt Chromium Tungsten is one of numerous metal alloys sold by American Elements under the trade name AE Alloys™.

Due to the high chromium content often found in cobalt alloys, the metal is sometimes called cobalt chrome. Cobalt is relatively new and until recently, wasn’t used in jewelry making.

But the most interesting thing about these new products is the increased interest of men to accessorize. Cobalt Chrome The specific type of cobalt alloy used to create cobalt rings is call cobalt chrome (CoCr). The chemical composition of CoCr is as follows. Chromium: 25-30% Molybdenum: 1% Tungsten: 2-15% Carbon: 0.25-3.3% Iron: 3% Silicone: 2% Manganese: 1% Cobalt: rest of the balance | often used for chrome replacement. Tungsten carbide cobalt chromium (WC Co Cr) and chrome carbide, CrC-NiCr are two of the most common powder materials used to replace chrome.

Color Cobalt chrome has a much lighter color compared to titanium and tungsten carbide. It has a very similar bright white color as platinum and white gold rings. Also, cobalt wedding bands are not plated with rhodium, the premium bright white color will stay forever.

There are a lot of downsides that come along with a tungsten carbide ring that has cobalt in it. For one thing, while you wear it, the cobalt in the ring will react with the natural oils produced by your skin. Cobalt rings will change your skin color, and over time they'll develop permanent oxidation spots that you'll never be able to scrub away. The alloy composition used in orthopedic implants is described in industry standard ASTM-F75: mainly cobalt, with 27 to 30% chromium, 5 to 7% molybdenum, and upper limits on other important elements such as less than 1% each of manganese and silicon, less than 0.75% iron, less than 0.5% nickel, and very small amounts of carbon, nitrogen, tungsten, phosphorus, sulfur, boron etc. First, the color of cobalt is a much whiter hue. Cobalt rings and cobalt chrome wedding bands are a much lighter metal, with shades more akin to white gold than tungsten.

Tungsten Carbide, which is better The surge in the materials used for the creation of jewellery has given the buyers with a lot of options. But the most interesting thing about these new products is the increased interest of men to accessorize. Fred Cuellar, The Diamond Guy, and Mark Mehaffey, ER physician, discuss dangers of removing tungsten and colbalt wedding bands. Equipment in cutting cobalt a CT2143-2 is a Tungsten Carbide Cobalt Chrome coating applied using the HVOF process. The coating is very dense, very hard, very well bonded and suitable for use in the most aggressive wear environments. The existence of Chrome within the matrix greatly enhances the corrosion resistance of this coating over traditional WC-Co(12) type HVOF coatings.
