Tungsten alloy shielding is necessary for radioactivity logging. Radioactivity logging is physical geographical method which used for researching geologic section of oil drilling, seeking oil, coal or other mineral resources and researching drilling engineering. Radioactivity logging has been widely used in prospection for coal field, uranium mine and oil and becomes one of important measures.

Both nuclear instrument and radioactivity logging utilize characteristics of α-ray, β-ray, γ-ray and neutron ray which released by radioactive isotope. Radioactive source, made of radioactive isotope which can releaseα-ray is called as α radioactive source. Radioactive source, made of radioactive isotope which can releaseβ-ray is called as β radioactive source. Radioactive source, made of radioactive isotope which can release neutron ray is called as neutron radioactive source

Compared with traditional material like lead, tungsten alloy shielding is more suitable for radioactivity logging. The density of tungsten alloy is higher twice than lead. So tungsten alloy has excellent radiation absorption. Otherwise, tungsten alloy is non-toxicity.

Tungsten remote control airplanes putty is a non-hardening, moldable material made from tungsten powder and a polymer binder. Under normal conditions, it will not harden. The minimum density is 10 g/cm³.

Tungsten remote control airplanes putty has been developed to have the maximum stickiness making it easy to use whatever the temperatu¬re. With a super high density tungsten formula (so you do not need to use much), it is ideal for fine tuning and balancing a neutral density presenta¬tion.

Tungsten is the world's 4th heaviest metal. It weighs up to 1.8x as much as lead and over 3x the weight of the Zinc/Pewter weights. Tungsten putty is the perfect weight for Remote Control Airplane toys .Tungsten is a safe non-toxic metal and it takes up less space in your Airplanes. Less space, means more weight concentration in the CG area, faster building time and more speed on the track.

Tungsten remote control airplanes putty can be easily used for fine-tuning the weight of airplane toys. Simply pinch off a piece of the putty, knead it until it is pliable, and press the putty into a cavity or hole on the airplanes.

Tungsten remote control airplanes putty has the following advantages:
• It's not lead, so it's environmentally friendly.
• It can be shaped in a slim profile to have less drag
• It's easy to add or take off to make subtle depth adjustments.
• Less chances of a leader break off because it comes off rather than being snagged.
• It's reusable

Cobalt, nickel binder used for powder metallurgy sintered tungsten alloy density, known as high-density alloy, also called heavy alloy. These alloys can be forged or heat treated to increase its density and strength. The tensile strength of tungsten alloys usually σb> 981MPa, hardness> HRC40.

Thermal conductivity of tungsten alloy than that of pure tungsten is small,granular chips, knife - chip contact length is short, high cutting temperature,prone to tumors and bonding tool wear. Requirements of tungsten alloy cutting tool material thermal conductivity, bending strength and hightoughness, good red hardness. Recommended selection of fine grain tungsten carbide-based ultra-fine grain carbide, such as YDl5, YM051 and so on.

Tungsten alloy cutting tool requires sharp, but also to ensure that edge strength. Tool geometry parameters can be selected: γO =- 8 º, αO = 8 º, Κr = 75 º, rε = 0.5mm. Cutting can be used: νC = 38m/min, f = 0.24mm / r, ap = 1mm. Cutting without cutting flui

Ballpoint pen or ball-pen is a kind of worldwide popular writing tools in recent decades. It has a simple structure, is easy to carry, provides writing lubrication and it is suitable used as autotype.

Tungsten alloy ball has many advantages, such as high density, small volume, excellent hardness, superior wearing resistance, high ultimate tensile strength, high ductility, high temperature resistance, etc. has a density twice that of steel and are more than 50% heavier than lead, so it is a very suitable material to make into ballpoint bead. These features provide stability when writing, so tungsten alloy ball pen bead will make writing easy and enjoyable. Its wear resistant is the key factor for the manufactures to produce tungsten alloy ball pen bead.

Tungsten alloy ball is used in the production of pen bead, tip of ballpoint is generally made of two kinds of material, and one is stainless steel beads and other kind is tungsten alloy ball pen bead. High quality ballpoint tip is made of pure tungsten ball. Ballpoint tip tungsten ball can be used for a long time, and makes writing is also very fluent.

Tungsten alloy ball pen bead is a kind of use the tiny round pearl rotation of the pen, the round pearl by brass, steel or made of tungsten alloy ball, can you write in ink onto the paper will release. Tungsten alloy ball pen bead is different with the reed pen, feather pen, metal tip pen and fountain pen.
