Yes in its pure form it can conduct electricity and is used mainly in electrical work. however unless it is smelted with other metals it is poisons to anything living. it is denser then titanium and stronger then titanium but at the same-time is heavier then titanium so pound for pound titanium is stronger but tungsten or wolfram is one of the only metals that is scratch resistant and keeps its polished look. as for rings it will be around when you 100th grandson or daughter need a wedding ring.

Why is copper better than graphite for electrical wiring?
because copper is a great conductor of electricity. graphite is also conductor of electricity. they use it in arc lamps, for example. graphite is an allotrope of carbon, which means that it is made of carbon rings. the rings are loosely bound together, so they flake off easily (why they use them in pencils). this makes it difficult to form into wires (microscopic wires are a different story, more about that at the end) The reason it conducts electricity is the structure of the rings. If they were arranged differently (like in a diamond) it would not conduct electricity. Diamonds are insulators. In fact, nanowires are very small conducting wires of graphite flakes folded onto themselves into tubes. They are the cutting edge of research in this field of physics.
Why does graphite conduct electricity and diamond does not?
: Diamond is made up of pure carbon. In the structure of diamond one carbon atom is attached to four other carbon atoms forming a covalent bond. All the electrons of each carbon atom is shared and the octet rule is satisfied. Hence no free electron is left for the conductance of electricity. : In case of graphite the carbon atoms naturally combine covalently with three other carbon atoms so every combined carbon has one unshared or free electron. Now this free electron is responsible for conductance in graphite. : Graphite and metals have free electrons to conduct electricity.

While extremely strong and scratch-resistant, tungsten carbide is a bit more brittle than traditional metals used in wedding bands.
How are tungsten inlay rings made?
First the tungsten carbide rings are from the raw tungsten carbide powder . The powders by high temperature polymerization into ring foetus. Ring foetus processing to polished, faceted, grooved and INLAID. To make tungsten inlay rings workers need a tool named carborundum grinding wheel to make the notch by machine design, then the Carbon Fiber, Gold, Silver or other inlay ended.
Has anyone been to TungstenFashionscom you want to buy a Tungsten Carbide Ring and they have the lowest prices?

Are tungsten rings strong or brittle?
Tungsten Carbide is a metal which is heavy-duty. This metal is usually used in parts of Oil rigs. It is really heavy and tough, almost as tough as titanium. The only difference between these two metals is that when you where a Titanium Ring it feels like feather, because of it's light weight. However, Tungsten Carbide is very heavy, and this you would definitely feel the ring on your finger. The purity of 99.98 industry tungsten metal(for rod, twisted wire and filament) is true brittle and easy to fracture. But for the tungsten jewelry like rings, pendants, bracelets and watches should not use the tungsten carbide alloy insead of pure tungsten. There contain 85.7% tungsten carbide and others should be titanium and so on. Tungsten carbide do not like the pure tungsten, it own a silver luster but much more shiny and bright. It's the hardest metal on the planet and do not brittle, the most famouse processing for tungsten carbide ring are the permanent polish. For the extremly hardness of tungsten carbide, jewelry it's polish shiny will keep a much longer period than other metals and define as permanent polish.
