Tungsten jewelry wholesale as gold substitution

Why tungsten alloy is used as gold substitution?

In theory, as its density is 19.1g/cm3, which is approximately 70% denser than lead, uranium could be used as material of making fake coin. However, it is weakly radioactive and not as dense as gold, so it does not appear to be a practical method.

Then people have discovered that tungsten is environmental-friendly, durable and hardness, the most important is that its density of 19.25g/cm3 is just about the same density as gold (19.3g/cm3), which bears the similar specific gravity. These advantages make tungsten enjoys the superiority to be the best substitute for the costly metal of gold or platinum. It is necessary to tell that alloying gold with tungsten would not work for several reasons but a coin with a tungsten center and gold all around it could not be detected as counterfeit by density measurement alone.

The appliances for tungsten alloy as gold substitution Tungsten jewelry wholesale

Nowadays, tungsten alloy is increasingly used in some field relevant to gold or platinum substitution, such as: jewelry, e.g. ring, ear ring, necklace, wrist chain, etc. Also, it is widely adopted in making faking coins, such as memorial crown.

Since tungsten alloy bears a special property of longevity and high durability, when it is utilized to make jewelry, it always implicate the love between lovers or couple could be everlasting. Its hardness makes it ideal for rings that will resist scratching, are hypoallergenic, and will not need polishing, which is especially useful in designs with a brushed finish.

Chinatungsten offer tungsten alloy as gold substitution

We are well accustomed to exploit more innovative applications of tungsten products. Gold-plated tungsten is one of our main products Tungsten jewelry wholesale

All of our tungsten carbide wedding bands are comfort-fit style, providing optimal comfort while wearing the ring and when putting it on or removing it. Because our tungsten carbide wedding bands are engineered to be maintenance free, we offer a lifetime warranty.

We can create a unique piece of jewelry with a style, polish, and texture that will last a lifetime. We offer tungsten carbide wedding bands with precious metal inlays of Sterling Silver, Platinum, Rose Gold, White Gold, and Yellow Gold. The tungsten carbide portion of the ring will maintain its original polish and luster for life, while the softer inlaid precious metals will eventually develop a textured appearance over time, creating an attractive contrast against the lasting polish of the tungsten carbide.

Tungsten rings are composed of a metal alloy, tungsten carbide. The alloy allows for maximum hardness and rigidity without sacrificing tensile strength. Each tungsten carbide ring is cut and polished with diamond tools. Tungsten rings are not sizable by ordinary jewelers' tools -- the metal is too hard. Most tungsten metal powder is converted to tungsten carbide (WC) by reaction with pure carbon powder, e.g. carbon black, at 900 - 2200°C in pusher or batch furnaces, a process called carburisation.

Tungsten jewelry wholesale is extremely hard and dense. Combined with carbon and other elements, it becomes tungsten carbide, which registers between 8-9 on the Mohs hardness scale. It's roughly 10 times harder than 18k gold and four times harder than titanium. In addition to its design and high polish, part of its attraction to consumers is its technical nature. It gleams a kind of luster that borders on the originality, making person be addicted to it, dulcify.

Hardness, assuring long lasting beauty. Permanently polished Tungsten rings take a brilliant high polish and resist scratching longer than any metal ever offered to the public. Tungsten rings will never bend out of shape.

Tungsten jewelry wholesale is hard, very hard. It ranges from 8 to 9 on the Mohs scale. By way of comparison, Titanium, a very hard metal, is about 6.5. Gold, Silver, and Platinum range from 2 to 4 on the scale. Sand ranks up there at 7 and your teeth, depending on your diet, range right around 4. The Mohs scale is more or less a "scratch test" so you can see why Tungsten is such a durable ring. Have some fun with them by trying to scratch them with a metal file. Titanium ring manufacturing companies routinely cut out their titanium rings using tungsten carbide cutting tools. There are just no rings that can compete with tungsten's durability.
