Products Description
Tungsten-based high specific gravity alloys are alloys composed of nickel and copper added to tungsten and other metallic elements added on top of that.Tungsten-nickel-copper high specific gravity alloy material is a class of alloy composed of tungsten as the base (W content 85% to 99%) with the addition of Ni, Cu, Co, Mo, Cr and other elements.
Custom-sized WNICU tungsten alloy bars are widely used in aerospace, military, medical, industrial, electronics, and oil drilling fields. With high density, strength, and excellent radiation absorption, they are ideal for making gyroscopes, armor-piercing shells, radiation shielding, counterweights, electrical contacts, and drilling components. These bars meet diverse high-performance demands in extreme environments.
Features of WNICU Tungsten Alloy Bar
High Density: The density ranges from 16.5 to 18.75 g/cm³, making it excellent for applications requiring heavy or dense materials.
High Strength: It has a tensile strength of 700 to 1000 MPa, so it can withstand high mechanical stress.
Excellent Radiation Absorption: Its radiation absorption is 30% to 40% higher than lead, giving it a clear advantage in radiation shielding.
High Thermal Conductivity: Its thermal conductivity is five times that of tool steel, allowing it to transfer heat quickly in high-temperature environments.
Low Thermal Expansion: Its thermal expansion coefficient is only half to one-third that of iron or steel, ensuring good dimensional stability under temperature changes.
Good Machinability: It is easy to machine and has good weldability and workability.
Application of WNICU Tungsten Alloy Bar
Aerospace Applications:
It is used to make gyroscope rotors, guidance components, and shock absorbers in aerospace. Its high density and low thermal expansion allow it to perform well in extreme conditions.
Military Applications:
It is used in armor-piercing projectiles because its high strength and density help penetrate tough armor.
Medical Applications:
It serves as radiation shielding (e.g., for cobalt-60 isotopes), as its excellent radiation absorption protects people from harmful rays.
Industrial Applications:
It is used in counterweights and hammer tips, as its high density and strength withstand heavy impacts.
Electronics Applications:
It is used in electrical contacts for high-voltage switches, since its good electrical and thermal conductivity ensures stable performance under high currents.
Oil Drilling Applications:
It is used in drilling equipment parts, as its high strength and wear resistance make it suitable for harsh working conditions.

FAQ
Are you a factory or manufacturer?
A: Yes, we are a factory but generally, we use our trading company to handle the business abroad. It will be convenient to receive the remittance and arrange the shipment.
What is the delivery method?
A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.
Why is your product so cost-effective?
A: We cut out the middlemen in the end-to-end manufacturing process. Rather than obtaining semi-finished goods from other suppliers, we obtain our raw material of APT powder directly from its source.
Do you do spot quality inspection or full inspection?
A: 100% full inspection. Inspectors will check the finished product individually, to ensure they adhere to all parameters. All unqualified products are discarded.
How do you ensure your lead time?
A: We have an efficient Order Management System, from material preparation to machining, and finally to a full inspection. Every stage of production is strictly monitored and controlled to give you an accurate delivery time.
What is the MOQ of Customized Size WNICU Tungsten Alloy Bar?
A: Depends on quantity, generally, no MOQ limit.
How to pay for it?
A: A bank transfer (T/T) will be acceptable.
What is the delivery time?
A: around 7-20 days which depends on the quantity and production.
What is kind of the package?
A: Generally, we use a carton case or plywood case with protective material inside to ensure the save of cargo
What is the lead time?
A: from order placed to cargo receiving will take around 10-25 days.
Why choose tungsten alloy over lead for radiation shielding?
A: Because it absorbs 30–40% more radiation than lead, is more durable, and is environmentally safer.
Can these bars withstand high temperatures?
A: Yes! Their high thermal conductivity and low expansion make them stable in extreme heat.
Are they easy to machine and weld?
A: Yes, they have good machinability and can be welded effectively for various applications.
What sizes are available?
A: We provide customized sizes to meet different industrial needs.
Why are they good for aerospace applications?
A: Their high density and low thermal expansion ensure reliability in extreme conditions like space travel.
How do they perform in oil drilling?
A: Their high strength and wear resistance make them last longer in harsh drilling environments.
Are they suitable for medical use?
A: Absolutely! They're non-toxic and highly effective for radiation protection in medical equipment.
Can they replace steel in industrial tools?
A: In many cases, yes-their strength, density, and heat resistance often outperform steel.
