Tungsten Alloy Brick

tungsten alloy brick is just one of many shapes of tungsten alloy.Tungsten heavy alloys generally are refractory metals with two-phase composition consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloys also contain Co, Mo, Cr, etc. They can be manufactured into various shapes, such as rod, cube, block, brick, ring, etc.

Applications of Tungsten Alloy Brick
Tungsten alloy can be manufactured for military applications, as extrusion die, various counterweights such as yacht counterweights, vehicle counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank counterweights, etc.

It is successfully used in so many applications because of its high density, high melting point, small capacity, excellent hardness, superior wearing resistance, high ultimate tensile strength, high temperature resistance, etc. Especially, Because of its good radiation adsorption capability, It is now widely used in manufacturing medical appliances, such as radiation shielding wall, block for CT facility, etc.

Applications of Tungsten Alloy Block

Coinciding with the properties above, usually , tungsten alloy can be manufactured as the parts of military defense, extrusion die, some counterweights, such as yacht counterweights, vehicle counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank counterweights, etc.

Extrusion die is one of the forming techniques used in material processing, consisting of forcing the work pieces through a die, thereby reducing its cross section and increasing its length. Tungsten alloy block is the popular material for extrusion die because of its high melting point and corrosion resistance.

Tungsten Alloy Block

Tungsten alloy block is the product with regular shape, such as square, rectangle and other regular shape. Nickel, Titanium and lead also implied in block. Why we choose tungsten alloy to be the materials of the product instead of them, the reasons are follows. It's have excellent electric and thermal characters with high density 16 g/cm3 to 18.5g/cm3, which is much higher than Nickel, Titanium and lead. Tungsten alloy blcok also have good mechanical strength and small coefficient of expansion and large elastic modulus.

Properties of Tungsten Alloy Block
tungsten alloy block Tungsten alloy block is a kind of W-based matrix with the W content of 85-99%. Keeping the primary tungsten phase properties alloy block density can be up to 16 .5-19.0g/cm3, making the product ideal counterweight for vehicles such as racing cars, airplanes and sailboats where size plays an important role. It's has excellent corrosion resistance and machinability.

The Advantages of Tungsten Alloy Block
Why we adopt tungsten alloy for parts of extrusion die instead of lead or aluminum or other materials' block? Because tungsten alloy has high melting point of more than ten times higher than lead, which is important in extrusion die process. Another reason is tungsten alloy's high hardness. Reason that is even more important is that tungsten alloy is environmentally friendly and non-toxic.

Tungsten Alloy Blank

Tungsten alloy blank is required form without any machining. The product can be produced by pressing and sintering metal powders into tungsten alloy rod, tungsten alloy plate, which are worked by rolling or swaging into rod, sheet, etc. Tungsten alloy rod is produced in straight random lengths with a smooth swaged surface at diameters 3mm and larger, and with a smooth drawn finish below 3mm. A center less ground finish of tungsten alloy can also be furnished.

Applications of Tungsten Alloy Blank
Tungsten billet/barrel as main body of professional darts;
Tungsten alloy rod, bar, cube, brick, block, tungsten alloy plate for various applications;
Counterweight used in yacht, sailboat, submarine and other vessels;
Ballast for aircraft, helicopter, F1 racing cars, and other vehicles;
Kinetic energy penetrators for defeating heavy armor;
 Radiation shield, radioactive source holder for nuclear U-power, X-ray, and medical instruments parts etc.;
Cubes/balls for bullet, rifle, missile and bomb ;
Screws/heads for golf club, flying fish sinker;
Bobs/vibrators for mobile phone, clock.

Application of Tungsten Alloy Bar

Typical Applications of tungsten alloy bar apart from boring bars, include weights and counterbalances for aircraft control surfaces and rotor blades, guidance platforms, counterbalances for flywheels, turbines and engine crankshafts, vibration reducing governors, filaments and fuse masses, ingredient kinds of heat-resistant steel and electrode, mainly used to guns, artillery, rockets, satellite, airplane and ship. Other applications include radiation shielding, gyro rotors, weapons including armor piercing applications, and high temperature tooling.

Advantages of Tungsten Alloy Bar

Tungsten alloy is often used in making tungsten alloy bar because it has a density ranging from 16.5 to 18.5 g/cm3, about 50 percent higher than lead and much higher than steel. It is easily machined, so designers of tungsten alloy boring bars can choose their shapes accordingly without worrying about the properties.

In addition, The product is less prone to chipping and breakage with good extensibility, has high melting point, wide working temperature range. When other metals start to melt while tungsten alloy keeps its properties.

Tungsten Alloy Bar

Tungsten alloy bar is consist of 85-99% tungsten with balanced commonly nickel and iron or copper. The alloys are made by liquid-phase sintering to give a structure consisting of almost pure tungsten particles in a matrix of the alloy elements.

tungsten alloy bar is enlarging a hole that has already been drilled or cast by means of a single-point cutting tool to achieve greater accuracy of the diameter of a hole such as in boring a cannon barrel. In addition, it can be used to cut a tapered hole.

There are various types of tungsten alloy boring bars. The tungsten alloy bar may be supported on both ends, but that only works if the existing hole is a through hole or it may be supported at one end. Line boring implies the former. Back boring is the process of reaching through an existing hole and then boring on the "back" side of the work piece.
