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.

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.

The Tungsten alloy product has revolutionized the art of worm fishing. You can now sense the bottom structure. Your ability to distinguish between sand, gravel, rock, mud and wood is now much easier than ever before. With the traditional lead weight, unless you went really heavy everything felt the same.

The other advantage is bait penetration in heavy cover. So many times over the years while flipping with lead weights, you would think that your bait is on the bottom and it isn't because it’s caught up in weeds. The smaller size and the extremely polished finish of a Tungsten alloy weight allow it to slip through heavy grass or cover and get to the bottom with ease.

There are 4 basic parts to a dart: the point, the barrel, the shaft and the flight.

The point of the dart is either steel or plastic known as soft tip. Other than this basic distinction, the other components of the dart are essentially the same for both steel-tip and soft-tip darts.

The essential part of the dart is the barrel, because the shaft, flight and even the point can be changed. Therefore, the darter should pick his/her dart on the basis of the barrel design that is best for them.

Most dart barrels are made of tungsten alloys. Better players use tungsten darts because tungsten is roughly twice as dense as brass, which means that, for the darts of the same weight, a tungsten dart is almost twice as thin as a brass dart. Tungsten is alloyed with nickel to give it strength. The higher the percentage of tungsten in the barrel is the better dart.

Darts can also be shaped differently to suit different throwing styles i.e. front weighted balanced or back weighted.  Because shafts and flights wear out regularly during play, darts are designed to allow for replacement of these parts. As a result, there are hundreds of different flights and shafts available, which allows the darter to customize his/her dart set.

Tungsten carbide blade’s high hardness, brittleness, poor thermal conductivity, heat shrink rate, should normally be carried out using diamond grinding wheel. But diamond grinding is expensive, difficult to repair wear and tear, so many factories still use ordinary grinding wheel. In the grinding process, because the higher hardness of tungsten carbide, the abrasive grains easily passivated ordinary wheel, intense friction surface the local temperature of the blade to form an additional thermal stress, can easily cause thermal deformation and thermal cracking, direct impact tool life and machining quality. 

Therefore, we should take the necessary measures to prevent tungsten carbide blade grinding cracks.

Very high percentages of tungsten, such as 98% tungsten darts, have a wonderful dense feel and a surface that resists wear for a long time. However, the high concentration of tungsten powder also makes them brittle, and more prone to break if dropped on hard surface such as a concrete garage floor. Very high density darts also are difficult to make, requiring special and expensive tooling to machine the barrels.

To get around those problems, most tungsten darts are now made of mixtures ranging from 70% to 95% tungsten. Lower density barrels are much cheaper, as they are easier to manufacture with automated machinery. Low density darts also has high wear resistance, from skin acid, friction, hitting other darts, falling on floors, etc.

The majority of steel-point darts used by competitive players in league and tournament play are now made of 90% Tungsten. Soft-tip darts are commonly made of 80% tungsten, which is cheaper, less dense, and less brittle. Soft-tip darts are prone to bounce out a lot, and electronic machines are often found in places with hard floors. The softer 80% tungsten darts are less likely to break, while constantly falling in such hard floors. As steel-point darts are more often played over carpeted areas, breakage is a little less of a problem.

Bristle dartboards for steel-point darts have a scoring are that is roughly 20% smaller than most soft-tip boards. With smaller scoring areas on a bristle board, the thinner diameter of 90% or 95% tungsten darts makes sense for competitive steel-point darters.

Budget priced darts are generally made of 80% or 70% Tungsten. Below 70%, most of the benefits of a tungsten dart are lost. Darts made of 60% tungsten or less are very bulky, and have poor wear resistance. The reason for making darts of 70% or less is to get the price down, which generally means taking other shortcuts in the machining process that also result in a lesser quality dart.

As with most products, tungsten darts are not all the same. Raw tungsten does not melt easily, and is not readily made into machinable shapes. Tungsten is generally ground into a fine powder, which is then blended with a variety of other metals that act as binding agents. In the case of darts, the most common blends contain nickel, with smaller amounts of copper and ferrous compounds.  The mixture is heated and compressed to make a solid billet or bar, which can then be machined into darts barrels.

Within each percentage range of tungsten darts, there is a wide range of quality. Every company has its own special blend of metals that are combined to make the raw billets. The best darts for competition are also the most expensive to make and the most difficult to machine. Cheaper darts can be made by adjusting the blend by adding softer metals.  For instance, a bit more copper or iron may be added. A "softer" blend means that cheaper cutting tools can be used, the tooling won't dull as quickly, and the machinery can produce more darts in a given amount of time.

Different blends may also slightly change the appearance of the finished darts. Some darts look shinier; others have a more grainy appearance. Surface treatments during the manufacturing process can also make a great difference in the appearance of a new set of darts. A wide variety of coatings are often applied to darts barrels, ranging from simple paint or powder-coating to high-tech vapor-deposit coatings such as Titanium Nitride.

What about the really cheap tungsten darts at the local "big-box" store?  Some darts advertised as "Tungsten" actually have very little tungsten content, even though at first glance they may look similar to a good quality dart. The main giveaway is that these cheap imitation darts will be much larger in diameter & length, for the same weight as a high-quality dart.  And the price may be substantially cheaper than most other Tungsten darts.  Think in terms of buying gold jewelry at a flea market. There would probably be little or no actual gold in that pretty bauble that sold for a super "bargain" price!

Some common sense rules are universal, no matter what the product is. If a price looks too low to be real, then the tungsten darts are probably not any sort of a bargain.

Tungsten alloy sea fishing is becoming more and more popular as more anglers prefer to search for the ultimate thrill in fishing.

That is exactly what you will get when you venture out (sea fishing) deep into the depths of the ocean where some of the biggest pieces of fish you will ever find are located.
