Products brief introduction
Of all metals in pure form, tungsten has the highest meeting point(3410℃,6192oF),lowest vapor pressure(at temperatures above,650℃,3000oF) and the highest tensile strength. It is the ideal material for ultra high temperature and high vacuum applications.
Tungsten has the lowest coefficient of thermal expansion (CTE) of ant pure metals, its CTE matches well with semiconductor materials, such as, Si, GaN, GaAs,,
,and it is stable at high temperature, make it the ideal material for electronic packing and seals.
Tungsten has a lower electrical resistivity than other refractory metals, but it will increase with temperature, this property is critical for high temperature furnace applications.
Also remarkable is its high density of 19.3 times that of water, Tungsten and its alloys, W-Ni-Cu or W-Ni-Fe has several advantages: high density (17.0-18.5g/
), good machinability, high modulus of elasticity and high absorption capacity x-rays and y-rays.

Tungsten Rod & Tungsten Bar Description
Tungsten rods and tungsten bars enjoy a wide range of applications thanks to their excellent properties. For example, tungsten rods and tungsten bars can be used as heat conductors, additives, crankshafts, cylinder barrels for automobiles, parts of heat-resistant steel, and electrodes. In addition, high-purity tungsten rods can also be used in guns, rockets, satellites, airplanes, ships, etc.
Tungsten Rod & Tungsten Bar Applications
Electrical and Electronics: Used as electrodes in welding applications due to their high melting point and excellent conductivity.Employed as high-voltage electrical contacts in electrical discharge machining (EDM) and electrical switches.
Aerospace: Utilized in aerospace components such as balance weights, counterweights, and control surfaces due to their high density and strength-to-weight ratio.
Medical: Found in radiation shielding applications, including X-ray equipment and radiotherapy machines, due to tungsten's ability to attenuate radiation.
Manufacturing: Used as tooling material for machining, milling, and drilling applications where high-density materials with exceptional hardness and wear resistance are required.
Defense: Employed in armor-piercing projectiles and kinetic energy penetrators for military applications due to tungsten's density and hardness.
Sports Equipment: Utilized in darts, fishing weights, and golf club heads due to tungsten's high density, allowing for compact and precise designs.
Chemical Industry: Found in chemical processing equipment such as crucibles, reaction vessels, and sputtering targets due to tungsten's resistance to corrosion and high temperatures.
