Tungsten skinny dropshot weight is great for coming through rocks and other underwater obstructions.

Tungsten skinny dropshot weight’s shape allows them to stay on top of cracks and narrow gaps in the rock, and the higher density of their tungsten composition makes them much more compact than comparable lead weights, which makes them extremely sensitive allowing you to feel every pebble across the bottom and the lightest of strikes. Tungsten is also much harder than lead, which means you can better detect anything your weight comes into contact with.

If you are new to drop shotting or having issues detecting subtle strikes, tungsten skinny dropshot weight is for you.

With the rapid development of science and technology and armor protection technology continues to improve, with a high density of tungsten alloy shells have become increasingly demanding, especially require both high strength and good toughness at ensuring high density premise. Therefore, how to enhance and improve the high-density tungsten alloy deformation of the enhanced strength and ductility is currently an important research direction.

Strengthening mechanisms are mainly tungsten alloy solid solution strengthening, dispersion strengthening, precipitation strengthening and interface strengthening and so on. There are solid solution strengthening elements Re, Mo, Nb, Ta, Ir and the like. Tungsten alloy Mo, Ta, Re, Nb, Hf, V, and Cr and other elements having the same w body centered cubic lattice; may be a solid solution in which w, but also to a certain extent, a solid solution in the binder phase , so as to achieve a solid solution strengthening tungsten heavy alloys, strengthening the role which the Hf largest, followed by Ta, Nb and re.

Enhanced dispersion strengthening, including direct and indirect strengthening, mainly from direct strengthen interaction of dislocations with dispersed particles, and indirectly strengthened mainly due to the high density of dislocations network composed of sub-grain interactions increase the strength of the alloy. Interface strengthening is to optimize the grain boundary (grain boundary strength to increase or decrease the impurities in the grain boundary segregation), and if the formation of a solid solution at the interface, the interface can enhance binding strength and to improve the material strength. Further, since having a good interface bonding phase is passed through the interface to the stress of the tungsten particles, which can effectively reduce the bearing capacity of the binder phase, the matrix phase and the adhesive coordinated deformation, reducing the occurrence of intergranular cracks, thereby improving strength of the material. Precipitation hardening methods to inhibit the precipitation phase precipitation hardening, precipitation hardening, and the second phase dispersion strengthening three kinds of tungsten. Inhibit the precipitation phase precipitation is an effective way to improve and enhance the performance of tungsten alloy, solid solution heat treatment process commonly used to avoid precipitation + quench phase precipitation, while suppressing impurity elements in the interface segregation in order to obtain relatively clean tungsten / matrix interface. In the W-Ni-Fe alloy of high density can be enhanced to add a small amount of Co relative to the base particles of tungsten wettability of the surface of the tungsten particles are more rounded, more conducive to plastic deformation of the alloy can enhance the tungsten particles and the matrix phase of the interfacial bond strength, thereby improving the strength and elongation of the alloy. Meanwhile, added Co, in the early phase sintering, iron and nickel to form preferentially with a low melting point, good mobility eutectic nicely promoting component atomic diffusion in the liquid phase, thus speeding up the process of liquid-phase sintering, refine the microstructure of the alloy.

Armor Piercing is one of the most common shells, hardness of the material is based on the shape of the shells, together with the kinetic energy of the firing transmission, when in contact with the surface of a hard target penetration failure to achieve the effect. Power depends on the kinetic energy penetrator bombs hit the target when, and physical properties of the material itself shells. Bore projectile was launched in the role after the drug resistance and accelerated collide only by gravity, in order to make the projectile hit the target when there is still a greater speed, armor-piercing must be used in the design tends to reduce the resistance of shape.

High density tungsten alloy is a class-based tungsten (tungsten mass fraction is usually 8O% ~ 97%), and added Ni, Fe, Mn, Co, Cu, Mo, Cr and other elements of the alloy, the density of up to 16 .5 ~ 19.0g / cm3. High density tungsten alloy not only density, but also has a series of excellent properties such as high strength, high hardness, ductility, good machining properties, thermal expansion coefficient, thermal conductivity, anti-oxidation and anti-corrosion can be good solderability and good. These properties make it excellent in the field of cutting-edge technology, military and civilian industry has been widely used, for example, as rod kinetic energy penetrator bomb core material, the counterweight components, inertial element ray shielding materials.

With main battle tanks, armored ships and a variety of increasingly strengthening military fortifications on the armor-piercing performance higher and higher requirements. High density tungsten alloy rod kinetic energy penetrators, not only has good armor-piercing power, and compared with depleted uranium alloy penetrators with non-toxic, non-radioactive contamination, etc., are the main countries in the world penetrator material and equipment, as well as the future development of the main projectile direction.

Tungsten dollar fishing sinkers also known as river fishing sinkers are best for river fishing because they plane up when retrieved and will avoid getting snagged when they are get back, but they do not hold the bottom well.

According to the two factors above, it is obvious that it is not a good idea to tungsten dollar fishing sinkers to be parts of rigs for sturgeon fishing, the reason is that these fish preferable for the fast water but the dollar sinkers are not fit to it. The fast current will constantly pick up and put down the coin sinkers.

For decades, lead is commonly used materials for the tungsten dollar fishing sinkers as it is easily machined. And the obvious advantage for the angler is its considerable weight for a given volume. One cubic foot of lead weighs 710 pounds while cast iron weighs only 470 pounds, copper 547 pounds, and silver 650 pounds. However, with the environment protection topic is becoming more and more serious, needing for environment-friendly material is urgency. Tungsten, with the properties of high density, about 30 percent higher than lead, and kindness to the environment stands out in the various alternatives. As a result, more hobbyists choose tungsten made sinkers when making fishing rig.
