Tungsten

Class 13

Tungsten has the second highest melting point of all elements. It is extremely dense and has low ductility. It is commonly used in cross wire welding copper and brass, resistance brazing, and welding of braided copper wire. It is also has many non-welding applications, such as filaments for incandescent light bulbs, x-ray filaments and targets, and penetrating projectiles.

CDA No. C74300

APPLICATIONS

• CROSS WIRE WELDING
• RESISTANCE BRAZING
• INCANDESCENT LIGHT BULB FILAMENTS
• X-RAY LIGHT BULB FILAMENTS
• PENETRATING PROJECTILES
• ROCKET NOZZLES

DESCRIPTION

Tungsten is a naturally occurring element that has the second highest melting point out of all the elements. This is why it has been so heavily used in circumstances that require the metal to sustain high temperatures. This includes aerospace applications, heating elements in electrical powered furnaces, etc. Additionally, it is both ductile and soft. The former makes it suitable for wiring, while the latter allows it to be cut easily. According to the metal standards set by the Resistance Welding Manufacturing Alliance, Tungsten is a class 13 material.
