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.

Tungsten powder is pure tungsten in powder, apparent black powder. The regular tungsten powder fearture with 2~10um, 99.90% or 99.95%. Tungsten powder used as material for tungsten product usually.

According to medical experts, tungsten is a metal, tungsten and its compounds are toxic and low toxicity. Although HIV is not yet clear, but the tungstate can interfere with the body's normal metabolism of molybdenum;Contacting with tungsten powder can cause mild upper respiratory tract irritation, dry cough, dyspnea, fever, heart palpitations, dizziness, loss of appetite, and olfactory dysfunction and other symptoms.

Tungsten carbide powder is the intermediate in the line from W powder to cemented carbides.  It can be produced from different raw materials and by different processes.  By far the biggest percentage is manufactured by the conventional method - carburization of tungsten powder - and covers the widest range of powder qualities in regard to average particle size (0.15–12µm).  All other methods in use yield very fine or very coarse powder grades.
The conventional process of carburisation comprises mixing of the respective tungsten powder of desired particle size with high purity carbon (lamp black or graphite) and reacting at temperatures between 1,300 to 1,600°C in hydrogen atmosphere.  The average particle size and particle size distribution of the original tungsten powder determine size and distribution of the WC powder.
The final carbon content of the WC Powder depends on the production mode of the hardmetal producer and is one item of the rigid specification, and varies from slightly sub-stoichiometric to stoichiometric (6.13% C) to slightly over-stoichiometric.  But not only is the carbon content specified but also a series of physical properties including: average particle size, particle size distribution, apparent (bulk) density and homogeneity.
High temperature carburised WC powders (1,700–2,200 °C) are usually coarse 10 to 50µm, but sometimes also 5 to 10µm grades are treated that way. The percentage of high temperature WC is small.
Tungsten Carbide Powder is often used to create hardmetals for cutting steel. Once mixed with cobalt and binder, tungsten carbide is pressed and sintered. Sintered tungsten carbide is one of the hardest substances known to man, and is used to cut steel, drill circuit boards and a multitude of other high tech applications in the automobile and aerospace industries, and beyond.

Characterization of Nanometer Tungsten Powder

Three types of nanometer tungsten powder were prepared by hydrogen reduction of three precursor powders at low temperatures, which were used as examples and were characterized by Brunauer-Emmer-Teller (BET) method, scanning electron microscopy (SEM) microscopy transmission electron microscopy (TEM), the scattering angle X-ray small (SAXS), issuing of the field of scanning electron microscopy (FESEM), respectively. The results showed that while SEM and BET would not characterize the size of dust particles of nanometers, they were important means to help to exclude (FESEM), respectively. no post-nanometer (FESEM), respectively . TEM and FESEM could directly measure the size of particle nanometers, but it needs much time to count the average particle size and size distribution. SAXS could not describe the state of agglomeration. Through a combination of FESEM and SAXS, the particle size, size distribution and particle shape of nanometer powders could be accurately characterized.

Characterization and application fields: nano tungsten powder can be used as additive materials for high density alloy and tungsten bar and wire, and as the matrix of superhard material, It also can be used as raw material for tungsten-rhenium alloy and tungsten carbide, and as the time-delay powder of safety explosive material, and as the combustible agent for explosive industry.

Packing: In sealed plastic bags with outer iron drums of 100/200 kgs net each.
