Features of tungsten alloy shielding:

Environmental properties:
Alloys with a small amount of nickel, iron, copper, etc. added to tungsten that is the main component are highly evaluated as environment-friendly material. Unlike lead, they are not resolved in water and have high oxidation performance.
Mechanical strength:
Our heavy metals have high mechanical strength to make these metals suitable for various shapes of weights and shafts that require especially high strength. For their high rigidity, our heavy metals work well in preventing chattering of holders and chucks of tools.
Machining/processing characteristics:
While pure tungsten is very difficult to machine or process, our heavy metals, while primarily composed of tungsten, are easy to machine with cemented carbide tools. Machining by milling machines and end mills and tapping are also possible. As their melting point is high, these heavy metals are also employed as high-temperature furnace members.

Composite tungsten electrode, which can be also called ternary complex of rare earth tungsten electrode, is mainly a mixture of thorium tungsten electrode(1% thorium), thoriated tungsten electrode(4% thorium) and yttrium tungsten electrode(2% yttrium), certainly, it can also mixing other rare earth oxide elements and adopting different mixing ratio. Usually, the composite tungsten electrode arc properties are superior to single tungsten electrode; and in the composite tungsten electrodes, tungsten electrodes of the ternary complex is better than the binary complex, the optimum ratio of oxides: CeO2: LaO3: Y2O3 = 1: 1: 3

Commonly used tungsten electrodes are pure tungsten electrode, cerium tungsten electrode, electrode, thorium tungsten electrode, lanthanum tungsten electrode and yttrium tungsten electrode, as well as ternary tungsten electrode.

Tungsten alloy materials are composed primarily of tungsten. Tungsten alloy can be manufactured by advanced powder metallurgy feature with very high density and excellent radiation shielding as well as mechanical strength and machining/processing characteristics. These metals have been well accepted as alternative materials to lead that has adverse impact on environment. They are also used for various weights and rotors and for their excellent shielding performance, in a variety of fields including medical equipment and nuclear power plants.

Features of tungsten alloy shielding:
High density:
Tungsten alloy having a density about two times that of copper and iron and is suitable for rotors and weights. In particular, it is very suitable for applications which a certain weight is required in a limited space and is well accepted to replace lead.
Radiation shielding properties:
Compared with other metals, tungsten alloy metals are far superior in terms of absorption of high-energy beams and radiation. They have extremely low gas emissions in high vacuum and are superior in mechanical strength and processing workability. They are ideal materials for such applications as medical equipment, nuclear power plants and other radiation shielding applications.

The bounce out is the most frustrating of all tungsten dart problems. You approach the line properly; flawlessly deliver the throw and your tungsten dart ends up on the floor. There is no sure-fire answer to stopping the tungsten dart bounce out. You are at the mercy of the tungsten dart gods. But how to stop tungsten dart bounce outs? there are few things you can do to minimize your chances of suffering through a bounce out.

Consider your tungsten dart weight. If you are using a light tungsten dart (18 to 21 grams) and you are experiencing a lot of bounce outs you might consider using a heavier tungsten dart. Do not change your tungsten dart weight too frequently, however. Changing your tungsten dart weight can take some getting used to, so consider this option carefully. It is a common fact that the lighter the tungsten dart the greater the chance it will bounce out.

Fixed vs. moveable tungsten dart points. Movable points have a spring that allows the tungsten dart tip to retract when it hits a hard service and continue its forward motion. The upside is you have a chance of minimizing bounce outs. The downside is that the tips can get loose and rattle in the middle of your throw. Another downside is that moveable point tungsten darts can be expensive.

Shoot wisely. You can take matters into you own hands and minimize your chances of bouncing off another tungsten dart by avoiding the other tungsten darts you have thrown. This may seem obvious, but sometimes we all fall victim to trying to force a tungsten dart into a spot that just won't fit. This attitude is the breeding ground for tungsten dart bounce outs. Take a moment to strategize and consider your alternate numbers. Always try to avoid a tight fit if you can.

Don't let your bounce outs phase you. The best way to deal with bounce outs is to forget about them. They happen to even the best tungsten dart throwers. Just remember one thing: Don’t let the tungsten dart that came bouncing back at you get you off your game. Stay focused on your number and forget about that bounce out. You have a new tungsten dart in your hand, make it count!
