Lead has a density of about 11.34 g/cm3, but with tungsten, you can achieve densities of up to 19.25 g/cm3, almost two times the density of lead, comparable to that of uranium (18.9 g/cm3) and gold (19.30 g/cm3). 

Higher density means smaller parts for the same weight, so tungsten is widely used in many areas such high-performance engine in battle plane、armor piercing bullet 、 shrapnel pits、counterweight in racing car、fishing sinker、 sailing boat、radiation shielding and so on.

Tungsten Carbide is a special compound composed of Tungsten and Carbon. It is also called Cemented Carbide.

Tungsten Carbide is not only a kind of black crystal with metal gloss, but also has similar hardness close to diamond. Besides, it has good corrosion resistant performance. It is obvious that such advantages can help to produce or make Tungsten Jewelry with high quality and distinctive design. First of all, its hardness close to diamond makes Tungsten Jewelry so wear-resistant that it’s difficult to be scratched and distorted. In addition, due to its metal gloss, Tungsten Jewelry always stays shiny as if it were a mirror. What’s more, its good corrosion resistant performance can contribute to making it impossible to fade, discolor and resistant to rust.

However, there are some disadvantages existed in Tungsten Carbide. For example, the great brittleness it possesses itself makes it impossible for Tungsten Jewelry to be inlayed in precious stone because it is easy to be broken under the influence of its producing process. What’s worse, it is difficult to be processed because of its strong hardness so that it is scarcely possible to produce Tungsten Jewelry with various design and style.

Tungsten is one of the most environmentally friendly metals.

As it is known that environmentally friendly (also eco-friendly, nature friendly, and green) is a ambiguous term used to refer to goods and services, laws, guidelines and policies claimed to inflict reduced, minimal, or no harm at all, upon ecosystems or the environment. This term most commonly refers to products that contribute to green living or practices that help conserve resources like water and energy. Eco-friendly products also prevent contributions to air, water and land pollution.

Tungsten is much more environmentally friendly than lead. In fact, according to the U.S. Government's Priority List of Hazardous Substances, which is a list, in order of priority, of substances that are most commonly found at facilities on the National Priorities List (NPL) and which are determined to pose the most significant potential threat to human health due to their known or suspected toxicity and potential for human exposure at these NPL sites, lead is the second most hazardous substance…..more please visit the web http://www.chinatungsten.com/Tungsten/Material-Safety-Data-Sheet.html

Tungsten carbide is a chemical compound formed by the union of tungsten and carbon.  Tungsten carbide has its applications widely in industries because of its own tungsten advantages including good corrosive resistance and high compressive strength (tungsten carbide's good performance at temperatures up to 800 degree). Of course, there are different kinds of  tungsten carbide products in many different fields, which mostly can be developed for use as  cutting tools, in machine tools applications, some used to produce jewelries. Besides, tungsten carbide has been also known for both its hardness and toughness, it's approximately three times stiffer than steel and much denser than steel or titanium. Therefore, thanks to its so long service life or its use  value, the more tungsten carbide products you possess, the more benefits you will save.
