Characteristics of Tungsten Rod
High Density: Pure tungsten has a density of approximately 19.3 g/cm³, making it one of the densest metals available. This high density gives tungsten rods excellent weight-to-strength ratio, making it an ideal material for components that require high strength and low weight.
High Melting Point: Pure tungsten has a melting point of 3410°C, making it one of the highest melting point metals. This property makes pure tungsten rods suitable for high-temperature applications where other materials would melt or deform.
Excellent Electrical Conductivity: Tungsten exhibits excellent electrical conductivity with a resistivity of 5.5 x 10^-8 Ωm. This property makes pure tungsten rods suitable for use in electrical components such as filaments, electrodes, and heating elements.
High Resistance to Corrosion and Wear: Pure tungsten has a protective oxide layer that resists corrosion and wear. This characteristic makes pure tungsten rods suitable for use in environments that are aggressive to other materials such as high-pressure or high-temperature gases or liquids.
Brittleness: Pure tungsten is relatively brittle compared to some other metals, making it more susceptible to cracking and failure under impact or bending loads. Therefore, special care should be taken when designing and fabricating components from pure tungsten rods to avoid stress concentrations and improper loading conditions.

Depending on the intended applications, tungsten rods and bars have three main surface finishes as follows:
Black: The surface is "as swaged" or "as drawn" , retaining a coating of processing lubricants and oxides.
Cleaned: The surface is chemically cleaned to remove all lubricants and oxides.
Ground: The surface is centerless ground to remove all coating and to achieve precise dimensions control.
Application Areas of Tungsten Rod
The hardness of tungsten is very high and close to gold, so it can improve the strength, hardness, and wear resistance of the steel, is an important alloying element, is widely used in all kinds of steel production, common tungsten steel are high-speed steel, tungsten steel, and tungsten cobalt magnetic steel, the steel is mainly used in the manufacture of various tools such as drills, milling cutter, wire drawing die, die and mold, etc.
Tungsten carbide has high wear resistance and refractory, its hardness is close to the diamond, which is often used in some hard alloy.
Tungsten carbide base hard alloy is generally can be divided into four types such as tungsten carbide - cobalt - tungsten carbide, titanium carbide - cobalt - tungsten carbide, titanium carbide, tantalum carbide - cobalt, and steel bonded hard alloy, the tungsten carbide base hard alloy is mainly used in the manufacture of cutting tools, mining tools and wire drawing dies, etc.
Tungsten is the highest melting point of all metals, the hardness is very high, so it is often used to produce strong heat and wear-resistant alloy, for example, tungsten, cobalt, chromium, and carbon alloy used to produce high strength and wear-resistant parts such as aviation engine valve, turbine impeller, etc, Tungsten and other refractory metals alloys are used to produce high strength parts such as air rocket engine nozzle.
Because tungsten has high density and high hardness, thus became the ideal material for making high proportion alloy. According to the composition, properties, and uses, the high proportion alloy is divided into W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag, and other major series, this alloy has many properties such as heavy, high strength, radiation absorption ability, thermal conductivity, and the thermal expansion coefficient, good conductive properties, weldability, and good processing, widely used in aerospace, aviation, military, oil drilling, electrical instrumentation, medical and other industries.
Tungsten is widely used in the electronics and power industry because of its high plasticity, low evaporation rate, high melting point, and high electron emission ability. For example, with the high light rate and long service life, so tungsten is widely used in the manufacture of various bulb filament, such as incandescent lamps, halogen lamps, tungsten wire can also be used in the manufacture of electronic tubes direct hot cathode, gate and a variety of electronic instruments by hot cathode heater. The properties of tungsten make it suitable for use in TIG welding and other similar materials.
The compound of tungsten is used as catalyst, and inorganic color, such as the two tungsten sulfide used as lubricant and catalyst in the synthesis of gasoline, tungsten oxide was used in painting, calcium or magnesium tungsten was used in fluorescent powder.
Because its thermal expansion is similar to that of borosilicate glass, it is used to make glass or metal seals. The sensitivity of tungsten is low, so it is used to produce high purity tungsten jewelry. In addition, tungsten was also used in radioactive medicine, some instruments will also use tungsten wire.
Certificate
Packaging of Tungsten Rod
The Tungsten Rod is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
