The longest commercial promise

The Longest Commercial Promise: Useful Thousands Years of Our Tungsten Heavy Alloy Paper Weight

You know I’m running a tungsten carbide and alloy factory in China, so I hope do something interesting of tungsten. One day, a nice ideas was born suddenly. Why do I make the most dense paper weight in the world by tungsten heavy alloy which with the density of nearly 19g/cc!

No more time to wait, I ask my engineers to find a mould which we produce bucking bars by it, mixed the highest density powder with Fe, Ni and Cu powder as binder metals, then we press it, pre-sintered and final sintered it by the temperature of 1600 degree. 3 hours latter, we got a large cube and also I ask my staff grounding it smoothly. Ask my friend who running a laser workshop to laser our log and company name and web site add onto it. Finally we have a excellent result. That’s a beautiful art! And that’s pretty paper weight, and I think it may be the first paper weight made from tungsten heavy alloy.

Last week, when I come to Shanhai to meet Ms. Keiko who come from Japan, I send the paper weight to her as a gift, when she asked me “ How it works?”

The answer from me was: one thousand year at least, I promise!

Everyone may find these paper weight at www.paper-weight.cn

About wolfram/alpha

I'm a man who have done business of tungsten(wolfram) for more than 20 years, I have offered tungsten intermediater products ad ammonium paratungstate and oxide tungsten, final tugnsten as tungsten powder and tungsten cemented carbide,tungsten heavy alloy products thousands tonnes. Then, I have also thousands reason to pay my attention to the institue of wolfram/alpha in the past years.

But, recently, I find the web of www.wolframalpha .com was open as a research engine which offers the researher a specific result but not milllions of the related pages as google, I'm very glad if anyone and/or any tools may give me a right result when i want find some information from the net for saveing time and meantine saveing my health.

Of course I should find something interested as tungsten, tungsten carbide and tungsten heavy alloys.but when I was showed the result of tungsten carbide , I found that useless information,even it was recorrecot info. if someone know tungsten or wolfram, who may find it as my feeling.

I do not know who created the pages and also I do not know if it was Mr. Wolfram's web. when I visit it, it seems just there's nothing but introducing how these guys to develop this web. so, I don't think that a nice way for me and that's realy a not googd idea of this web.

It was just one thing interesting, I think, for I'm a man who do biz of wolfram, and Mr.Wolfram is another man who named wolfram but dose not know wolfram.

That's all

China puts ceiling on 2009 output of tungsten ore, antimony, rare earth

China puts ceiling on 2009 output of tungsten ore, antimony, rare earth

China said Thursday it would impose a ceiling on the output of mineral resources like tungsten, antimony and rare earth in 2009 amid shrinking demand.
The move is aimed to protect China's reserves of these minerals, the Ministry of Land and Resources said in an online statement.
The country's tungsten ore concentrate output is limited to 68,555 tonnes this year; rare earth ore to 82,320 tonnes, and antimony ore to 90,180 tonnes, said the ministry.
These quotas on output were based on decreasing demand across the world as a result of the ongoing global financial crisis, said the ministry.
The ministry said it would also not take any license applications before June 30, 2010 for exploring the three resources.
China holds 40.5 percent of the world's proven tungsten reserves, and is the world's biggest antimony producer. The nation has a proven rare earth reserve of 52 million tonnes, or about 58 percent of the world's total.
The country started to cap the annual output of tungsten in 2002 and that of rare earth in 2006. It is the first time such restrictions have been placed on antimony.
The ceiling on tungsten ore concentrates (with tungsten trioxide content above 65 percent) last year was 66,850 tonnes, and that on rare earth ore at 87,620 tonnes.
The ministry said such caps are intended to stabilize global demand and supply of these products and ensure their sustainable use.

Tungsten Heavy Alloy Bucking Bar and Rivert Gun

Tungsten Heavy Alloy Bucking Bar and Rivert Gun
A rivet gun is a type of tool used to drive rivets. Nearly all rivet guns are pneumatically powered. The rivet gun is used on the manufactured head side of the rivet and a bucking bar is used on the buck-tail side of the rivet. Those rivet guns used to drive rivets in structural steel are quite large while those used in aircraft assembly are easily held in one hand. A rivet gun differs from an air hammer in the precision of the driving force.Rivet guns vary in size and shape and have a variety of handles and grips. Pneumatic rivet guns typically have a regulator which adjusts the amount of air entering the tool. Regulated air entering passes through the throttle valve which is typically controlled by a trigger in the hand grip. When the trigger is squeezed, the throttle valve opens, allowing the pressurized air to flow into the piston. As the piston moves, a port opens allow the air pressure to escape. The piston strikes against the rivet set. The force on the rivet set pushes the rivet into the work and against the buck. The buck deforms the tail of the rivet. The piston is returned to the original position by a spring or the shifting of a valve allowing air to drive the piston back to the starting position.Contents1 Types 1.1 One-shot gun 1.2 Slow-hitting gun 1.3 Fast-hitting gun 1.4 Corner riveter 1.5 Squeeze riveter 2 See also 3 References TypesIn aircraft work, there are several types of rivet guns:One-shot gunThe one-shot gun is designed to drive the rivet in just one blow. It is larger and heavier than other types and is generally used for heavy riveting. Each time the trigger is depressed, the gun strikes one blow. It is rather difficult to control on light-gauge metal. Under general suitable conditions it is the fastest method of riveting.Slow-hitting gunThe slow-hitting gun strikes multiple blows as long as the trigger is held down. The repetition rate is about 2,500 blows-per-minute (bpm). It is easier to control than a one-hit gun. This is probably the most common type of rivet gun in use.Fast-hitting gunThe fast-hitting gun strikes multiple light-weight blows at a high rate as long as the trigger is held down. These are repeated in the range of 2,500 to 5,000 bpm. The fast-hitting gun, sometimes referred to as a vibrator, is generally used with softer rivets.Corner riveterThe corner riveter is a compact rivet gun that can be used in close spaces. The rivet is driven at right-angles to handle by a very short barreled driverSqueeze riveterThis gun is different from the above rivet guns in that the air pressure is used to provide a squeezing action that compresses the rivet from both sides rather than distinct blows. The squeeze riveter can only be used close to the edge because of the limited depth of the anvil. Once properly adjusted, the squeeze riveter will produce very uniform rivet bucks. The stationary (fixed) jaw is placed against the head and the buck is compressed by the action of the gun.See alsoRiveting machines Machine Orbital riveting ReferencesBureau of Naval Personnel - [US] Navy Training Course Aviation Structural Mechanic S 3 & 2 NavPers 10308-A.

What’s the meaning of the new Chinese Central Government’s policy of “Stop Release New Licence of Developing Tungsten and/or Rare Earth Mines”?


According to the reported of CTIA, the Chinese Central Government(CCG) has just announced a new policy of developing tungsten and rare earth mine in 2009-2010, it is reported that none can get the new licence for developing such stagitic nonferrous metals such as tungsten, rare earth from 2009 to 2010. the reason given were envoirement protection, the more and more domestic applications and the out of control of opening and developing of these important materials in the past decades sharp econominc developing.

But, according managers of the majior nonferrous metals company and experts of tungsten and rare earth in China, in fact, the total sum of output and tungsten and rare earth in 2009 maybe less than the plan and total export licence of 2009, the reason is has been down sharply from the last half 0f 2008, some companies who have licences and deal these products in domestic and outside, just exported 20%-50% these commodities inn the first quarter 2009, and there’s no more purchase order for the next quaoter. Then, their views is it may be better in the end of this year, or if the global economic come to better later than it is expected, the market of these nonferrous metals’ prices and output may rise also later than expected by the end of 2009.

Why the CCG announced this new policy at this situation?

I think the reason may 1) CCG would like to let the world know, the cheap markets on the stagitic metals from China will never come in the future; 2) The CCG will control the export of nonferrous metals as W & RE, for there’s a large demand in the domestic, 3) CCG would like show it’s strict policy for the enviorment although all over the world have been in the the large financial crisis, 4) CCG has the weapons itself in the resource “war” in the new century, not the cannon, not the rokets and not the Chinese, but these metals which may controlled by CCG.

The new policy may let more and more Chinese companies who produce and export tungsten ore and/or tungsten intermediate products reduce less it’s production and offer more and more tungsten final products and then, these countries and companies who use the raw materials as tungsten intermediate products as ammonium paratungstate, metatungstate, tungsten acid, tungsten oxide and trioxide to buy tungsten final products and the machined tungsten carbide and alloy parts in the near future.

Then, the new policy just show us a policy was all these companies have to think about the processing and trade stagtic of using tungsten as raw materials.
