Some prize moments of genius from tungsten darts' most excitable commentator - Sid Waddell.

There are some interesting tungsten darts quotations:

"That's the greatest comeback since Lazarus."

"When Alexander of Macedonia was 33, he cried salt tears because there were no more worlds to conquer. Bristow's only 27."

"If we'd had Phil Taylor at Hastings against the Normans, they'd have gone home."

"He's as cool as a prized marrow!"

"You couldn't get more excitement here if Elvis Presley walked in eating a chip sandwich!"

"He's playing out of his pie crust."

"He looks about as happy as a penguin in a microwave."

"He's been burning the midnight oil at both ends."

"Tungsten darts players are probably a lot fitter than most footballers in overall body strength."

"Trying to read Reyes's mind is like trying to read the mind of Jabba the Hutt"

"These guys look calm but inside they are as nervous as a vampire who knows there's a sale at the wooden stake shop in the morning."

"That was like watching Popeye when he found his spinach!"

"He's as twitchy as a frog in a blender"

"He's going like the Loch Ness Monster with a following wind!"

"Keith Deller is like Long John Silver - he's badly in need of another leg."

"He looks as happy as a scorpion who's just had a pedicure!"

"Eyes like a pterodactyl....with contact lenses"

"Cliff Lazarenko's jumping up and down like a gorilla saying "give me back my banana!"

On Bobby George - "He's like a Sherman tank on roller skates coming down a mountain!"

"He's twitching more than a one legged ferret!"

"He's moving with the purpose of a Panzer Division"

"He may practice 12 hours a day, but he's not shy of the burger van!"

"He's like Jack the Ripper on a Friday night."

"He's got one foot in the frying pan and one on thin ice."

"Tarantino re-writing Gunfight at the OK Corral couldn't have done any better than this."

Titanium carbide (TiC) is an extremely hard refractory material with high melting temperature, and high thermal shock and abrasion resistance. It is used mainly for powder metallurgical parts including cutting tool tips, dies, wear parts and resistant coating. In industry, the manufacturing of Cu-W composites is usually done through infiltration of Cu into a porous, pre-sintered tungsten compact, or through the liquid phase sintering of compacts pressed from mixed powder.

In some researches, Cu-W/TiC was investigated and fabricated through liquid phase sintering. In is reported that the additive metals (iron, cobalt and nickel) can enhance densification in the liquid phase sintering of Cu-W. In order to increase the densification of the Cu-W matrix, nickel (Ni) was introduced. In addition, the densification of Cu-W/TiC sintered electrodes can be improved by the addition of Ni. However, due to the insolubility of Cu, W and Tic, and the amount of Cu apparently reduced by the cold welding in ball milling, porosity cannot be avoided. Nevertheless, with increasing TiC, the distribution of the particle size becomes narrow.

Due to the high thermal conductivity of Cu, and the better spark erosion resistance, low thermal expansion coefficient and high melting temperature of W, copper-tungsten electrodes have been widely used for machining die steel and tungsten carbide work-piece. The materials normally used in EDM electrodes are various types of copper, graphite, tungsten, brass and silver. But copper-tungsten has better properties. The low melting point of Cu reduces the resistance to electrode wear.

At high tungsten content, there is porosity in the liquid phase sintered electrode due to the insolubility between the Cu and W. This greatly impedes densification during the solution-reprecipitation stage of liquid phase sintering. Hence, this makes it necessary to introduce another material with high melting point. Materials having good electrical and thermal conductivity with a high melting point are used preferably in copper-based electrodes to resist electrode shape-loss.

With its high density, tungsten alloy is the ideal metal for military defense. Tungsten is non-toxic, and environmentally friendly material. Tungsten alloy cubes for military defense can easily replace lead in most cases.

Having more concentrated weight means having more control to achieve the center of mass that you are targeting. Owing to its great hardness and resistance to high temperature, tungsten has been increasingly adopted in military defense increasingly today. Especially the tungsten alloy cubes, is often produced in various sizes fit to different military defense, such as: shot gun, armor piercing bullets, penetrates armor, mutilate tanks, self-propelled guns, armored vehicles, ships, aircraft, or any other armored target and so on.

Advantages of Tungsten Alloy Cubes for Military Defense:

1, High-density

2, High absorption capacity against X-rays and gamma rays

3, Good modulus of elasticity

4, High hardness

5, Environment protection standard

The scorekeeper’s "10 Commandments" for keeping tungsten dart score:

 1. Scorekeepers shall not talk while keeping score!

 2. Scorekeepers shall not move about while keeping score, stand still!

 3. Scorekeepers shall not look at the shooter, stand facing the board!

 4. Scorekeepers shall not call out a score, of one tungsten dart or all three -- unless the shooter asks you!

 5. Scorekeepers shall not tell a shooter what to shoot or what combination to shoot for an out!

 6. Scorekeepers shall not change a score unless it is brought to the attention of both shooters (teams).

 7. Scorekeepers shall not change a score - regardless - if that player (team) has shot again and a second score written down. An error in a shooter's score MUST be corrected before he (team) shoots again or it stands.

 8. Scorekeepers shall not lean out to see where a tungsten dart is or is going nor shall he follow the darts with body or head movement!

 9. Scorekeepers shall not show any sign of disgust or excitement while at the scoreboard!

10. Scorekeeper shall not drink or smoke while scoring.

According to applications, tungsten copper electrode can be specifically divided into resistance welding electrode, EDM electrode and the electrode of high pressure discharge tube, etc.

3. High Pressure Discharge Tube

Discharge tube is a kind of device for preventing from high voltage in input. If the voltage of two ends is high than the limit, there will be internal short circuit and absorb the input high voltage. Combine the high density and high melt point of tungsten with the good plasticity and excellent conductivity of Cu, tungsten copper electrode uses fine tungsten powder and Cu powder and through high temperature sintering and isostatic pressing.

In addition, for tungsten carbide steel, high carbon steel, hardened tool steel using common copper electrode, which has high wastage, low precision, low speed of machining and other shortcomings, the use of tungsten steel high conductivity, high melting point, small thermal expansion, it can remarkably improve the speed and accuracy of machining.

Electrical discharge machining (EDM) has high energy density of pulse discharge, short duration pulse discharge, do not contact with the work-piece, variable structure for simplifying and requires small macro force and other properties. In the early, Electrical discharge machining (EDM) often use Cu or graphite as electrodes, which is cheap and easy to be ablated.

However, tungsten copper has good high temperature resistance, high strength under high temperature, arc resistance, excellent conductivity and radiating so that it can be widely used in EDM, resistance welding and high pressure discharge tube electrode. The electrode for EDM is various, as tungsten copper electrode, it should be high density and good uniformity, especially rod, pipe and other shapes of electrodes. In addition, due to the advantage of tungsten, tungsten copper has high electrical speed, low wear rate, accurate shape and excellent anti-corrosion, which increases the accuracy of products.
