HD17BB Machinable Tungsten Rod

HD17BB is kind of alloy which same as tungsten heavy alloys illustrate the advantages of microencapsulated powders. Tungsten heavy alloys generally are refractory metal which have two-phase composites consisting of W-Ni-Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added rare earth and/or other metals as Co,Mo,Cr, etc.

The HD17BB Machinable Tungsten Rod is widely used in industries such as aerospace, medical, defense, machining, and oil & gas. It can be used to manufacture aircraft counterweights, medical radiation shielding, lathe tool holders, and drilling casings. With its high density, strength, and excellent machinability, it meets diverse industrial needs.

High Density & Strength:
The HD17BB Machinable Tungsten Rod has an extremely high density of 17 g/cm³, with a tensile strength of 130,000 psi and yield strength of 90,000 psi. These properties make it perfect for high-load applications and precise weight distribution, such as aerospace counterweights and machining tool holders.

Excellent Machinability:
Although tungsten is naturally brittle, HD17BB contains alloying elements like nickel, copper, and iron to improve its toughness. It can be easily machined using standard methods like turning, milling, and drilling, with high efficiency and smooth surface finishes.

Superior Thermal Performance:
This material has outstanding thermal conductivity (96 W/m·K), which is 3-4 times higher than steel. It quickly dissipates heat, reducing thermal buildup. Its low thermal expansion (5.4 µm/m·°C, 20-400°C) ensures better dimensional stability under high temperatures, preventing thermal fatigue.

Corrosion & Oxidation Resistance:
With an extremely high melting point (~3400°C), HD17BB resists oxidation in high-temperature environments. It also has good corrosion resistance against most chemicals, making it suitable for various industrial uses.

Slight Magnetism:
HD17BB is weakly magnetic, which may need consideration in sensitive applications. However, special heat treatments can further reduce its magnetism if required.

Eco-Friendly & Sustainable:
Compared to traditional tungsten alloys, HD17BB produces less waste during manufacturing and has high recyclability. Its high density also means less material is needed for the same weight, lowering costs and environmental impact.

Aerospace:
Used to make aerospace components like rotor blades, propellers, inertial systems, fluid control systems, and balancing weights. Its high density helps optimize weight distribution.

Medical Field:
Used in medical devices such as collimators (for X-rays and radiation therapy), medical isotope production, transport and storage containers, and various radiation shielding parts.

Defense & Security:
Used to produce balancing weights, radiation shielding devices, and large container inspection equipment.

Machining:
Serves as lathe tool holders for vibration-free machining, improving precision.

Oil & Gas:
Used to make casing materials for drilling operations. These casings need to be heavy enough to penetrate mud and withstand high hydrostatic pressure.

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 HD17BB Machinable Tungsten Rod?

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.
