Natural granite fishing weights are a good choice because they look like a natural part of the environment. The natural stone weights are smaller than comparable lead weights because they absorb water and get heavier.

Since tungsten alloy fishing sinker introduction to the fishing market, anglers everywhere have found Tungsten weights to be a far superior product to their lead-based predecessors. Tungsten's higher density allows these sinkers to outperform lead sinkers twice their size. Furthermore, tungsten has low bioavailability and does not pose a pollution risk.

So as for density, tungsten alloy fishing sinker is outweigh granite fishing sinker.

Tungsten carbide CNC tool can be divided into conventional tools and modular tooling two categories. The modular tool is the developmental direction. The main advantage of developmental modular tool are the followings:

1.Reducing tool change downtime, increase production and processing time;

2.Accelerating tool change and setup time, improve the economy of small batch production;

3.Improving standardization and rationalization of the tool;

4.Promoting the management and flexible processing tool level;

5.Expanding the utilization of the tool, give full play to the performance of the tool;

6.Effectively eliminating work disruptions measurement tool, can be preset outside the line.

In fact, due to the development module of the tool, tungsten carbide CNC tool has formed a three systems, namely turning tool systems, drilling and boring and milling tool system tool system.

Bismuth is a brittle metal and fairly rare. Fishing tackle made from bismuth usually is a bismuth tin alloy. Twenty-five per cent lighter than lead, bismuth weights will sink more slowly than a lead weight.

Tungsten alloy fishing sinker is smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. The advantages to weights made of Tungsten alloy include the size and hardness of the weights. Another advantage of a Tungsten weight is Tungsten is harder and allows for more feel by the angler.

For the best option, tungsten alloy fishing sinker is better than bismuth fishing sinker in terms of its ability of sinking fast.

Just about any sport equipment needs to be cleaned regularly to remove sweat, dirt, etc., yet it never occurs to most people that their tungsten darts also need cleaning.

To greatly extend the useful life of tungsten darts, clean them regularly. Any mild cleaner that can remove oil will do: moist towelettes (wipes) are great (alcohol based ones not the ones that contain hand lotion!) or hand soap.

By cleaning tungsten darts you will not only make them last longer, but will also restore much of the grip by removing both the slippery feeling and the particles filling-in the hollows of the knurling.

Through processing practice, summed up the other process measures in grinding sharpening can effectively prevent or reduce tungsten carbide blade grinding crack sharpening process.

Less rigid shank, the tool will hold less instably. It may cause the spindle run-out produce grinding cracks, so the machine tools, grinding wheels, fixtures and tooling consists of processing the system should have sufficient rigidity, and should be controlled Axial and radial run-out wheel. Factors causing cracks sharpening tungsten carbide tools produce more, only the appropriate choice of wheel, while using the grinding process fair, in order to avoid cracks, progressive grinding quality.

Due to processing practice, summed up the measure that adopting fair amount of grinding sharpening can effectively prevent or reduce tungsten carbide blade grinding crack sharpening process.

If there are too much friction in tungsten carbide tool grinding sharpening process, grinding can lead to a sharp rise in temperature, the blade prone to burst, so fair selection of grinding parameters is very important. A fair amount of common ground: peripheral speed v = 10 ~ 15m/min, feed f vertical = 0.5 ~ 1.0m/min, f cross = 0.01 ~ 0.02mm / trip. When hand grinding, longitudinal and cross feed volume is not too large.

A good replacement for lead shot sinkers is ceramic sinkers. Ceramic sinkers are easy to cast and don't snag on the bottom when reeling in your line.

 Tungsten and tungsten nickel alloy fishing weights are very durable, harder than steel and 25 per cent smaller than comparable lead weights. Tungsten and tungsten nickel alloy fishing sinkers are available as barrel weights, bullet weights and ball slip shot weights. Tungsten weights 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.

The sinker should be made of refractory materials at high temperature. Heavy weight should be attached to immerse the sinker by taking account of high density metal. Tungsten has an atomic weight of 183.84 and a melting point of 3,422. this make it quite suitable for making fishing sinker than ceramic which has lower melting point and less destiny.

With processing practice, summed up the use with molybdenum disulfide infiltration wheel can effectively prevent or reduce tungsten carbide blade crack sharpening process measures.

With molybdenum disulfide infiltration wheel at room temperature, the powder of molybdenum disulfide is made with a mixed solution of ethanol and then in a sealed container (to prevent volatilization of ethanol) new ordinary wheel immersed in a mixed solution, 14 hours After removing the naturally dried for 18 to 20 hours, so that the grinding wheel is completely dry. The wheel in the internal voids filled with the above-described process, molybdenum disulfide, the lubricating particles may play a role in the grinding wheel chip good clogging. Tests confirmed that when using molybdenum disulfide had infiltrated carbide blade grinding wheel, grinding sharp, abrasive easy passivation, the work-piece deformation is small, smooth chip removal, debris zonal basic shape, you can take away most of the grinding heat, thereby improving the grinding effect, progressive tungsten carbide blade yield.

By processing practice, summed up the negative edge sharpening method can effectively prevent or reduce tungsten carbide blade grinding crack sharpening process.

The negative edge sharpening method is in front of the sharpening knives , firstly the surface of the rake face or knife blade grind a negative band. Tungsten carbide materials are brittle, because while the grinding wheel that the tool vibration impact loads, vibration prone to cracking; Meanwhile, instant heating and cooling of the grinding zone thermal stress may exceed the ultimate strength of cemented carbide and thermal cracking . Using negative edge blade sharpening method can improve the strength and enhance the capacity of the blade vibration and shock loads and increases heated area to prevent a large number of guide blade grinding heat, thereby reducing or preventing cracks.
