Aggressive jigging

Tungsten’s turbo sink-rate isn’t just about bypassing unproductive water to get to active fish. Its fast fall also triggers bites.

“You can really move tungsten around and create heavy jigging strokes,” Brosdahl said. “A slow, natural fall is nice when you’ve got a cold front or are dealing with really finicky fish, but when fish are aggressive a fast fall triggers them. And, you’ve always got the option to play cat-and-mouse with a crappie by slowly pulling the jig away from them.”

Fast jigging strokes become increasingly critical at night. After crappie lose interest in glow-painted baits, Brosdahl finds vibration becomes the dominant fish attractant in the dark. Compared to lead, a tungsten jig can be pounded and twitched more aggressively to create heavy vibrations and call-in crappie by “talking to their lateral line.”

Straight, fast drop

Compared to a lead jig of equal size, a tungsten one is heavier and sinks faster. This has advantages in many crappie scenarios.

Cover water - Tungsten’s fast drop allows anglers to rapidly fish a hole. This makes prospecting more efficient, especially in deep water. Consider how it’s easier to cover water in a boat using a lure you can cast a country mile versus one with a limited range. On ice, every hole represents a cast. Fast-sinking tungsten makes quick work of covering the water column, bypassing unproductive sections, and determining if fish are around.

Get back to biters - A high-speed drop lets anglers capitalize on brief, feeding windows. The faster the bait returns to the strike zone, the more crappie one can catch during short-lived bites.
Straight down - In addition to sinking fast, a round tungsten jig drops straight down. This makes it well suited when a precise drop is needed to avoid snags around timber, vegetation, and rock cribs.
Making clouds - A heavy tungsten jig is a great tool for banging bottom to attract fish. Make impact with the floor, snap the jig up, and let it smack the silt again. Do this a few times to stir up the bottom and create silt clouds. The sediment plume attracts crappie.

At times, Brosdahl uses a heavy spoon to make massive silt clouds, then reels up and switches to a small jig. Tungsten makes this 1-2 punch fast and efficient.

Density desirables - A tungsten jig emits ticking sounds when hit on hard bottom.

Brosdahl uses this tactic more for crayfish-eating jumbo perch, but finds banging tungsten can attract crappie when fishing hard-bottom areas or isolated rock piles.

Accelerated fall - Tungsten sinks well on a spinning outfit. No complaints here. But, these days Brosdahl often uses a straight-line reel, like the Frabill 371, for more speed.

The 371’s ultra-smooth, free spool quickly feeds-out 3-pound fluorocarbon, helping tungsten jigs reach terminal velocity on the drop. The fact straight-line reels eliminate line twist is a bonus when it’s time to finesse a slab to hit.

Tungsten ice jigs are a hot trend on hard-water. Lure selections from manufacturers are growing, and more anglers are seeing the unique advantages tungsten provides on ice.

Small jigs that “fish heavy” are a main ingredient for many crappie ice fishing tactics. Since tungsten is much denser and approximately 30-percent heavier than lead, it gives new options for jig-size and weight combinations. This has benefits when downsizing, for instance. Tungsten also sinks faster than a similarly sized lead jig, which is an asset in deep water.

Ice-fishing guru and full-time guide, Brian “Bro” Brosdahl of Max, Minn., is well versed in the virtues of tungsten jigs for crappie. Here are 4 reasons tungsten jigs are standard in his ice fishing box:

Punch slush
Fast drop
Aggressive jigging
Great for downsizing

Punch slush
“Tungsten punches through a slushy hole nicely without needing to go to a gaudy-sized lead jig,” Brosdahl said. “This reason alone is why I use tungsten so often.”

To appreciate this statement, we must take a page from Brosdahl’s stealth fishing handbook. To Bro, slush is your friend. While most anglers scoop it out, he kicks extra slush into a freshly drilled hole. The reason: a slushy hole reduces light penetration for a more natural setting below. In contrast, a clean, slush-free hole allows a spotlight-like beam to shine in water, which can spook clear-water crappie.

The challenge is getting a small bait through the thick, icy soup. For tiny lead jigs, Brosdahl often uses a method he calls jousting. With the jig at the rod tip, he thrusts the rod into the slush to get the tiny jig below the debris before opening the bail and letting the bait sink. He’s never broke a rod, but he’s seen others snap sticks trying the method.

With tungsten, jousting is rarely needed. Average-sized tungsten jigs easily punch through slush. When the slush is extra thick, or when using a tiny tungsten jig, Bro makes a pilot hole in the slush with his Humminbird transducer.

Brosdahl admits he sometimes needs to reach in and pull a big crappie through the slush to land it. But, it’s a small hurdle and a better option than not hooking them at all.

Tungsten as a strategic non-ferrous metals, because nature has a high melting point, high elastic modulus, high hardness, good thermal conductivity and excellent fracture toughness, they are applied to cemented carbide, high-density tungsten alloy, tungsten wire, tungsten and many other fields. With the development of modern industrial technology, the traditional tungsten powders made of tungsten products has been difficult to meet industry needs. And a large part of the quality factor depends on the performance of tungsten products tungsten powder raw material, and therefore its need to prepare good performance tungsten products, must be prepared by the excellent quality of tungsten powder.

You can make use of X-ray diffraction, scanning electron microscopy and surface area analyzer to study the process of W powder phase structure, evolution and mechanism of powder morphology and particle size reduction of WO3. WO3 during the restore sequence into WO2.9, WO2.72, WO2, eventually reduced to W. W in WO3 powders hydrogen reduction process, smoothing rule WO3 has hexahedral rough topography becomes a hexahedral, and with the reduction process, the larger secondary particles into smaller particles. In the hydrogen reduction of WO3 and WO2.72 WO2.90 process, the powder specific surface area is increasing, decreasing powder size, but reduced to the WO2.72 and WO2 WO2 reduced to W in the process, the powder specific surface decreases, increasing the particle size of the powder.

Brown tungsten oxide (WOZ) is tungsten trioxide in the manufacture of WO_2.2 reduction under reducing conditions after a long period.

1.Paratungstate reduction was due to tungsten metal powder particles may have a shape of APT, it should pay attention to the morphology of APT. We APT having nearly cubic or monoclinic equiaxed grain structure, the crystal has some cracks.

2. The blue tungsten oxide decomposition at 404℃ and hydrogen atmosphere APT blue tungsten oxide obtained in morphology. The overall shape and APT same, but the blue tungsten oxide particles have more cracks than APT, some particles are also broken for a few. APT tungsten trioxide we used to get, and its appearance is very similar with APT.

3.Purple oxide, tungsten oxide, tungsten purple WO₂ morphology. Compared with the blue tungsten oxide, its appearance has changed significantly. Each piece by a large number of small columnar arrangement messy crystals. However, the entire collection of WO_2.72 small columnar grain morphology still has the APT.

4. Brown tungsten oxide morphology pure tungsten dioxide. This is the APT tungsten dioxide as raw material to go through the blue tungsten oxide and tungsten oxide phase purple system. Most WO_2.72 columnar crystals into a sleek flat particles.

In the oxidation of hydrogen reduction process of tungsten, tungsten oxide may arise have their specific morphology, but it still has the secondary particles tend to leave iron tungstate appearance. During the restore process, the changing size of the particles. Size tungsten powder in a considerable extent, depends on the reduction of the size of tungsten oxide intermediates. From blue or purple oxide, tungsten oxide, tungsten to tungsten oxide reduction this stage, tungsten powder particle size has a decisive impact.

In the role of external excitation source, a substance or a system has undergone significant changes in the color of the phenomenon known as discoloration. When the photochromic compound A subject refers to a certain wavelength of light irradiation, the photochemical reaction can occur to give the product B, color A and B is significantly different. B irradiation or by heating the additional beam of light can be restored to its original form A. Photochromic (Photochromism) is occurring under the action of a light reversible chemical reactions. As a transition metal oxide, tungsten oxide film is an excellent photochromic material, the study found tungsten oxide under UV light will turn blue. Because photochromic properties of tungsten oxide in the optical information storage, optical control, optical switches, field optics materials, optical information such as genetic material has broad application prospects and attracted much attention.

Photochromic effect mechanism of nano tungsten oxide film photochromic tungsten oxide accompanied by reversible oxidation - reduction reactions, discoloration mechanism available now widely recognized in 1975 by Faughnan proposed double charge injection / extraction model to explain that in the ultraviolet Under irradiation, valence band electrons are excited into the conduction band, and generates electron-hole pairs photogenerated electrons are then W (VI) to capture, generate W (V), while reducing species photogenerated holes or interior surface oxide film generating proton H +, implanted inside the film, and the reduced oxides generated blue tungsten bronze HxWO3, blue as a result of W (V) in the valence band electrons into the W (VI) conduction band transitions. W6 (A) + W5 (B) <=> W5 (A) + W6 (B), due to the above change does not disrupt the crystalline structure of the material, and therefore the oxidation of the photochromic effect with good reversibility and fatigue tungsten material performance.
