Sep 18, 2019· Tungsten Wedding Bands Like your love, tungsten wedding bands can last forever. Tungsten carbide is among the strongest metals on Earth, according to the Mohs Scale of Mineral Hardness.It's harder than steel and titanium, and 10 times harder than gold, making these rings are scratch-resistant and durable.They won't lose their shape over time, and can stand up to the wear and …
Since the last 1960s tungsten carbide has been considered as an anode material for hydrogen or methanol fuel cells . Binder et al. studied the oxidation of hydrogen on WC electrodes in a H 2 SO 4 solution. Hydrogen oxidation occurred at low potential, without affecting the catalyst. Corrosion of the tungsten carbide occurred at potential higher ...
Tungsten carbide is an alloy of elements including tungsten, nickel, tantalum, niobium, titanium and chromium. High quality tungsten carbide, like that used in our Tungsten Forever™ tungsten rings, is composed with a large percentage of tungsten, giving the alloy the inherent hardness and dark-grey color tungsten implies.
Jan 02, 2012· Depositing tungsten carbide particles into a molten weld puddle is not new, although the process has become very popular in the last fifteen years. This method of applying tungsten carbide as hardfacing for applications requiring extreme abrasion resistance will result in unprecedented wear life.
Tungsten carbide is an alloy of tungsten, nickel, tantalum, niobium, titanium and chromium—and it's even harder, ranking 9 out of 10 on the Mohs Scale. Our durable tungsten carbide rings for men can even be laser engraved with a personalized message. A …
Carbide scrap became very important in the late 1960's and early 1970's. The reasons were probably many; new applications in metal working, mining and wear parts were creating an ever increasing demand. The world supply of raw tungsten was somewhat limited at the time. Scrap carbide became more and more in demand.

Rocklin manufacturing Co. of sioux City, Iowa entered the tungsten car-bide deposition field in the mid-1960s with what they call the NRocklinizer,O a piece of equipment that applies a ...
Jan 21, 2015· Chemical compounds of tungsten are used for many purposes. Cemented tungsten carbide, a hard substance used to make grinding wheels and cutting or forming tools, is the most common tungsten compound. Other tungsten compounds are used in ceramic pigments, as fire retardant coatings for fabrics, and as fade-resistant dyes for fabrics.
Cemented carbide is a hard material used extensively as cutting tool material, as well as other industrial applications.It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of "carbide" or "tungsten carbide" in industrial contexts ...
