Appearance of tungsten wire:
The tungsten wire is coated with colloidal graphite on the surface and tungsten appears uniform black. Tungsten wire appears metal luster if being removed colloidal graphite.
Tungsten wire supply:
We supply pure tungsten wire, tantalum tungsten alloy wire, tungsten copper alloy wire and other tungsten alloy wire. Our tungsten wire supply ability is 10 tons per month.
The delivery time of tungsten wire is 7 to 30 days after confirmation.
Tungsten wire is the best material to make lamp bulb.
In our daily life, there are a lot of metals that can give light besides tungsten filament light bulb, such as copper wire, iron wire, etc.. While, why do we select the tungsten material as the luminous body of bulb? Zhengzhou Sanhui Co., Ltd will explain how tungsten wire give out light to you?
Because the tungsten filament has relatively high electric resistance and melting point, when the electric current goes through the tungsten wire, the electric resistance of tungsten wire rises and gives out heat, then tungsten wire and tungsten alloy wire give out light. At the same time, the melting point of tungsten wire is very high, so tungsten wire is not easily to be burnt out. In addition, inert gas- neon is filled in the bulb, which ensures tungsten wire is not able to be oxidized when the tungsten wire is generating heat. Since the passing of electric current makes the conductor heat. When the temperature of tungsten wire rises, the length of radiated electromagnetic wave becomes short. At room temperature, tungsten wire can radiate ultrared rays. When the temperature rises to a certain degree, tungsten wire begins to radiate visible light, so tungsten wire begins to give out light.
Compared with tungsten wire, other metals would be burnt out before giving out light and also have certain risk. So tungsten wire is the best choice to make bulb.

According to the water feature the fishing jigs used in, fishing jigs can be divided into two types, crappie fishing jigs and salty water fishing jigs.
And fishing jigs also can be classified into five types due the different head shape of fishing jigs. They are the bullet fishing jigs, football fishing jigs, rocker fishing jigs, mega bite football fishing jig and weedless brush fishing jigs.
Owing to the different body materials of fishing jigs, there are four types of fishing jigs, bucktail fishing jigs, nylon fishing jigs, Mylar fishing jigs and feathered fishing jigs, of which come in different size and shape. Bucktail jigs, just as the name implies, this kind of fishing jigs have the body made of bucktail .And bucktail jigs are the most popular used between anglers.

The selection of tungsten concentrate and APT
1) Tungsten concentrate and APT are good varieties, from the point of price advantage, the price of tungsten concentrate it is indisputable fact,leading the APT and even the whole industry chain.But tungsten concentrate is not standardized, lack of national standard and possible adulteration and other adverse factors. As our tungsten concentrate a large number of mining, no high quality new mines at present stage, found that the original mining grade decreases faster, as if choosing tungsten concentrate trading varieties, the whole delivery, inventory and inspection will be unable to standardization.
2) Tungsten industry chain are dominant oligopoly by China Minmetals Corporation, more than 55% of the mining controlled by China Minmetals Corporation.
3)In contrast, APT is larger in circulation, and the downstream demand is widespread.What's more, APT global industry acceptance is high,and standardization is easy, compared to tungsten concentrate more suitable for access to the exchange platform for trading. In terms of Prices, despite the APT not as the leading role of tungsten concentrate, but APT is the direct product of tungsten concentrate, in the front end of the industrial chain, and the correlation is high, the price of tungsten concentrate more for trading.
The advantage of replacing tungsten bars with APT
1) Tungsten (APT) replace tungsten bars is not involved in the change of the industry, but we use better liquidity (APT) replaced the tungsten bars, tungsten from export data is not difficult to draw tungsten (APT) the advantage position in the export of tungsten. On the other hand, the global LED lighting is a big trend, the original tungsten bars, one of the main use of traditional lighting industry showed a trend of shrinking, with a wider range of application of tungsten (APT) replace tungsten bars to save for a rainy day.
2) The strategic of tungsten is a scarce resource, China tungsten based reserves decline rate significantly increased, and the demand for tungsten industrial has obvious rigid, even at the present stage in the global economy is still in a slow recovery, tungsten industry still maintain the contrarian steadily rising trend. Began earlier this year, the national level to start the purchase and storage mechanism, tungsten leader China minmetals also purchasing measures, comprehensively promote domestic tungsten industry chain prices, APT price breakthrough in the middle of June 200000. From tungsten concentrate mining quotas have fallen sharply this year also can verify the national level the strategic position began to focus on this kind of rare metals tungsten.
3) From the tungsten concentrate and APT past price trends, not obvious at this stage of recovery in the global economy, the tungsten industry chain has been out of the apparent rebound in prices stabilising, believe that with further warming global macro economy, after the tungsten (APT) replace tungsten bars, the variety of goods and capital capacity may show significantly increased; Price activity and market participation could improve significantly.

Generally, a dark colored jig with a big crawfish trailer does a great job imitating a crawfish, and a white color jig does a good job of imitating a baitfish.
It is a reasonable to matching fishing jig color to the water conditions.
In clear water, light colors such as white, chartreuse, green tend to work the best. Because transparent jig skirts and transparent crawfish-type trailers cast less of a silhouette and are less threatening to spooky bass.
While in murky water, black, brown, purple and contrasting dark colors often produce best.

When selecting fishing jig size, keep in mind the two factors, first is the smaller baits are generally best whenever they can be used, and the capacity of feeling the action of a jig .These two factors guide your choice of fishing jig size.
Use the lightest bait and line you can as smaller and slower baits and thinner line with low visibility will almost always catch more fish than big one. Unless the following salutations, do not do not switch to a heavier jig.
Firstly you can tell what's going on with your bait underwater.Or it's a windy day you go for fishing or there's a strong current. And if you are fishing in deep water, it takes too long for a light jig to sink, so you can choose a heavier jig.
What is more, if the water is muddy, a compact 1/2 ounce more bait is more effective, because the smaller one is much more effective in clear water.
