Tungsten Carbide Rod Surface Roughness

Tungsten carbide rods have high hardness and abrasion resistance and thus its grinding process is quite complicated, which includes: coarse grinding, fine grinding, accurate grinding and polishing. There are two types of polishing: matte polishing and mirror polishing. And if necessary, it will have to be supplemented by electrolytic reaming. 
 
Grinding can help cemented carbide rods get higher machining accuracy and lower surface roughness. Grinding precision usually reaches IT6 ~ IT7 tolerance grade, while surface roughness reaching Ra1.25 ~ 0.16μm. If tungsten carbide rods are polished, their surface roughness will be up to Ra0.1 μm, which makes its surface be smooth as that of a mirror. Its dimensional accuracy and shape accuracy can be within 1um, the error of which is equivalent to 1/70 thickness of human hair or even thinner. 
 
Surface roughness Ra of tungsten carbide rods before accurate grinding should be smaller than 6.3um.

Tungsten Carbide Three Screw Hole Rod

Tungsten carbide three screw hole rod has stable mechanical properties and good weldability. It also has high abrasion resistance and impact resistance, and is mainly used in the manufacture of drills, milling cutters, reamers, and other cemented carbide tools. Three screw holes provide cooling in the machining process, which greatly enhance the usability and durability of the tools. The main types of tungsten carbide three screw hole rods include C type-30 °, W type-30 ° and W-type 40 °, etc. Now in China, companies with mature technology to manufacture three screw hole cemented carbide rods are still few.

Advantages of Tungsten Fishing Beads

 A major advantage of having tungsten fishing beads incorporated into your favorite fly patterns is that they provide an element of flash to fly patterns by reflecting sunlight that has penetrated the water's surface.

A trout's diet naturally consists of approximately 90 percent aquatic insects so anything that you can do to your favorite nymph pattern to help get the trout's attention will pay big dividends. When tungsten fishing beads nymph anglers need to understand how fast a fly is going to sink. Experimenting with leader lengths and different sizes and types of beads will be needed to understand how fast the flies will sink. Using the countdown method after the cast will accurately let the fly angler know what level of the water column he or she is fishing.

In most cases when presenting flies to fishing holding in deep holes the smaller more aggressive fish will strike the fly closer to the surface. Getting the fly down deep and rolling it along the bottom will improve your chances of hooking the real lunker in the hole.

Slotted Tungsten Beads

Trout and lots of fishes mostly feed on nymphs and aquatics that live in the water, not on the surface. If you want to angle effectively near the bottom in a deep, powerful stream or river or get deeper in a lake. How do you quickly get the fly down deep? Applying slotted tungsten beads with fishing line is rightly the answer.

Slotted tungsten beads are made of tungsten which is about 70% heavier than lead and is more than twice as heavy than brass. It is also corrosion resistance, so that it can adapt to the sea environment, which is salty. Furthermore, which is more important to us, it is non-toxic. Therefore, using slotted tungsten beads is much friendlier to the environment.

Slotted tungsten beads have high density, which is the reason for fishing hook can go deeper in deep sea or lake, and become more powerful in powerful stream. Slotted tungsten beads are preferred by those who have a tendency to fish in deep sea.

Tungsten Fishing Beads

Tungsten fishing beads are standard in the industry and have been worked into almost every famous bead pattern available on the market.

Tungsten fishing beads are made of tungsten, which is considerably heavier than lead, are used not only to provoke the fish to bite, but also to force the fly to sink the bottom. On standard bead heads there is one small and one large bored-out hole to help to slide it easily around the hook bend and fit snuggly behind the hook eye.

Tungsten fishing beads are made exclusively for fly tiers using a "duel-diameter" hole. One small and one large bored-out hole to help slide easily around the hook bend and fit snuggly behind the hook eye. These beads are plated to resist tarnishing and provide flash even in the most stained of waters.

All serious fly fishermen know that having tungsten fishing beads, flies works wonders for catch rates when fishing fast, clear streams. They also work wonders in any other deep water situation! Get the flies to the bottom where the fish are and you just HAVE to catch more fish!

Reasons to choose tungsten as material of fishing beads

Tungsten is one of the heaviest metals available. It is so heavy that can be used in making in tungsten fishing beads. Tungsten has a density of rages from 16.5 grams/cm3 to 18.5 grams/cm3 near room temperature, in comparison, lead only has a density of 11.34 grams cm-3.As a result, tungsten fishing beads are almost twice as heavy as lead in the same volume.
