What is Tungsten?
Tungsten, originally named “wolfram,” is a rare earth metal known for its high hardness, high density, and high tensile strength. It is naturally corrosion-resistant and has the highest melting point of all metals, exceeding 3000°F (approximately 1593°C). Pure tungsten also possesses considerable ductility even in its unalloyed state.
Furthermore, tungsten is one of the hardest naturally occurring elements on Earth. Although its melting and boiling points are among the highest of all known elements, it almost always exists in compounds with other elements. Tungsten is a versatile and environmentally friendly metal, but its high hardness and brittleness can make processing tungsten products relatively difficult.
Like other metals such as niobium, molybdenum, tantalum, and rhenium, tungsten is chemically stable. It is also very stable, possessing the lowest coefficient of thermal expansion of all metals, and exhibits strong resistance to creep, the tendency of a metal to undergo plastic deformation under stress and high temperatures.
What are Tungsten Alloys?
Tungsten alloys are primarily composed of tungsten, mixed with small amounts of other metallic elements such as nickel, copper, titanium, or iron. These alloys typically conform to industry standards ASTM-B-777, AMS-T-21014, and AMS-7725. Because tungsten has a high density, extremely high hardness, and a high melting point, like other refractory metals, it cannot be cast, forged, or rolled like other metals. Instead, it must be pressed into powder form and then sintered. It is frequently alloyed with other metals, such as super duplex steel, tool steel, and high-speed steel.
Challenges of Tungsten Machining
Tungsten and other hard, brittle materials are notoriously difficult to machine. Machining tungsten requires years of trial and error to master and demands rigid fixtures and minimal spindle runout. Only the most skilled machinists can effectively machine tungsten. Careful adjustment of feed and cutting speeds is crucial to balancing tool life and machining time. Too high a machining speed can cause tool breakage or damage to the part; too low a speed results in inefficiency and high costs. Our team meticulously studies the client’s project design before machining to determine the optimal manufacturing process.
This process involves close collaboration and communication with the client’s engineering team to identify the most suitable design and manufacturing approach for your project, meeting the required part design requirements. Our experienced team can keep the cost and delivery time of tungsten CNC part projects within reasonable limits.
Tungsten Alloy Grades
Comprehensive selection of ASTM B777 compliant tungsten alloys for diverse applications.
Tungsten Carbide (Cemented Carbide)
Tungsten carbide is a composite material made of tungsten carbide (WC) particles and a binder phase (usually cobalt (Co) or nickel (Ni)). Known for its extremely high hardness, cemented carbide is suitable for manufacturing cutting tools, drill bits, and wear-resistant parts.
Heavy Tungsten Alloys (W-Ni-Fe, W-Ni-Cu)
These alloys are typically composed of tungsten, nickel, and iron or copper. They have high density and are used in ballasts, vibration dampers, and aerospace components.
Tungsten Nickel Copper (W-Ni-Cu)
This tungsten alloy is typically composed of tungsten, nickel, and copper. It combines density, machinability, and electrical conductivity, making it suitable for manufacturing electrical contacts, radiation shielding, and aerospace components.
Tungsten Nickel Iron (W-Ni-Fe)
Alloys of tungsten with nickel and iron are used in a variety of applications, including counterweights, balances, and rotating inertia components.
Tungsten-Rhenium (W-Re)
Tungsten-rhenium alloys combine tungsten and rhenium (Re) to improve their high-temperature strength and ductility. They have applications in aerospace and electronics, such as in thermocouples and high-temperature heating elements.

For production, our usual lead time is 20-30 days. However, the lead time may vary slightly depending on the product and quantity. If your order is urgent, please contact us and we will do our best to solve your problem. For shipping, we usually use express and air freight. Express takes approximately 7-10 days, and air freight takes approximately 3-5 days. If the customer requests sea freight, we will ship by sea, which usually takes 40-50 days. Intellectual Property and Confidentiality Agreements?
We understand that your 3D data and designs are crucial to your business. Therefore, we place great importance on protecting your intellectual property. We use SSL encryption to encrypt all transmitted files, ensuring they are not intercepted during upload to our servers. All information and files you upload to our platform are securely stored and shared only internally with employees who need access to this information to produce the parts you require.

If you require further protection, we can sign a confidentiality agreement.
First, we ensure we fully understand all customer requirements. Then, we place the order with the production and inspection departments. Each production stage undergoes self-inspection to ensure everything is in order. Before shipment, all products must be inspected by the inspection department to confirm they meet customer requirements before entering the packaging department. If they do not meet requirements, the products will be sent back to the production department for repair or rework.
All our products undergo rigorous inspection and secure packaging before shipment. Each production stage is inspected to ensure good product quality. The inspection department will conduct a re-inspection to ensure everything is perfect. However, if a quality problem does occur, we sincerely apologize and will take full responsibility. We will do our best to repair or remanufacture the product to properly resolve all issues.
Due to the material's high hardness, it is best to use a carbide drill bit or a solid carbide drill bit.
Use a straight flute high-alloy tap. For small holes, a thread-forming tap can be used. Considering the difficulty of machining tungsten, thread milling may be more suitable than tapping.
This material has an extremely high density, therefore a high-torque CNC machine tool is required. It is highly wear-prone to tools, so high-quality carbide tools must be used, and tool life should be checked frequently as it wears out quickly.
