In theory, as the density of uranium is 19.1g/cm3, which is approximately 70% denser than lead, tungsten gold plated bar and tungsten alloy gold bar could be used as material of making fake gold products. However, tungsten alloy gold bar 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 import ant 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 alloy gold bar and tungsten gold plated bar enjoys the superiority to be the best gold substitution for the costly metal of gold or platinum.

The bell fishing jigs  feature a bell-shaped design with a swiveling hook fastened to the top. These fishing sinkers cast well in the wind, making them a favorite for shore anglers.

The rounded profile of the fishing sinkers also reduces its chance of snagging. For boat anglers, bell fishing sinkers are often used on a three-way rig.

This rig is designed to get baits deep without needing any extra equipment, like downriggers. The rig consists of a three-way swivel with one eye for the main line. The next loop holds a drop line with a bell sinker at its end.

Finally, the last loop holds a leader and a lure or a live bait rig. The rig is effective when bounced along the bottom or lowered to a desired depth and trolled in open water.

Tungsten carbide is the most widely used type of high speed machining (HSM) cutting tool material, this kind of material is produced by powder metallurgy process, and consists of hard carbide particles (usually a tungsten carbide WC) and the soft metal bond. At present, there are hundreds of different composition of WC cemented carbide, where cobalt (Co) are used as the binder, nickel (Ni) and chromium (Cr) is also a common bond element. In addition, you can also add other alloying elements. Why there are so many carbide grades? Cutting tools manufacturers how to select the right cutting tool material for a certain cutting machining?

The hardness and toughness WC-Co tungsten carbide has the unique superiority in both hardness and toughness. Tungsten carbide (WC) itself has the very high hardness (more than corundum or aluminum oxide), and its hardness is rarely drop when work temperature become higher. However, it lacks enough toughness, which is essential for a cutting tool performance. In order to use the high hardness of tungsten carbide, and improve its toughness, people will use metal bond tungsten carbide together, so that the material has far more than the hardness of high speed steel, at the same time, it can withstand cutting force in most machining. In addition, it also can withstand the cutting heat generated by high speed machining.

Tungsten alloy fishing sinkers are made by rare metal – tungsten. It is an ideal substitute of the lead fishing sinker. Tungsten heavy alloys concentrate maximum weight in the smallest possible space.

They are often used as counterweight in sporting field, such as balancing, tungsten heavy alloy fishing sinkers, golf weights, etc.

Tungsten alloy fishing sinkers are an ideal, environmentally friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard. They are harder than steel and extremely dense, tungsten being on average 30 percent smaller than its lead counterpart is.
Meanwhile, they are smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. Tungsten is also used in the production of other fishing applications, such as tungsten-carbide line cutters and tungsten powder coating for fishing lines.
