Clean Tungsten Wire

Clean tungsten wire is white tungsten wire which is the tungsten wire produced by alkaline washing or electrolytic polishing of black tungsten wire. Compared with black tungsten wire, the surface of white tungsten wire is smooth, bright, and clean. Shortly after alkaline washing, the white tungsten wire has a silver gray metallic luster.

The surface of electrolytic polished tungsten wire shall be smooth, clean gray silver with metal luster, The tungsten wire features excellent formability, long life and super lighting efficiency , Mainly applied for making various electron tube, H series auto lamp, balogen lamp and other special lamp.

Density: ≥ 19.20g/cm3

Purity: Doped tungsten containing W>99.92%, pure tungsten containing W>99.95%

This type of tungsten wire has a smooth and clean surface, with a uniform silver gray metallic luster. The wire diameter is uniform, the processing performance is good, the filament life is long, and the light efficiency is high. Widely used in the vacuum industry to produce various types of electronic tubes. Filaments for H-series automotive lamps, halogen lamps, and other special light bulbs produced in the electric light source industry.

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 Clean Tungsten Wire?

A: Depends on quantity, generally, no MOQ limit.

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.

What is the purity level of clean tungsten wire?

Clean tungsten wire typically has a high purity level, often reaching 99.95% or higher, with minimal impurities.

How does clean tungsten wire differ from black tungsten wire?

Surface Quality: Clean tungsten wire has a smooth surface without graphite coating or excess oxides, unlike black tungsten wire.

Applications: It is preferred in high-precision fields like electronics and medical devices, whereas black tungsten wire is often used where surface finish is less critical.

What are the key advantages of clean tungsten wire?

High strength (can withstand significant tensile forces)

Excellent electrical conductivity

Superior surface smoothness

High-temperature resistance (melting point ~3,422°C)

Why is clean tungsten wire preferred in medical and electronic applications?

Due to its high purity, smooth surface, and reliable electrical performance, it ensures precision, durability, and minimal contamination risk in sensitive applications.

Can clean tungsten wire be used in extreme temperatures?

Yes, thanks to its extremely high melting point (~3,422°C) and thermal stability, it is ideal for high-temperature environments.

Is clean tungsten wire corrosion-resistant?

While tungsten itself is highly resistant to corrosion and oxidation, prolonged exposure to certain harsh environments (e.g., strong acids or oxidizing conditions at high temperatures) may require additional protective coatings.

What diameters are available for clean tungsten wire?

It comes in various diameters, ranging from ultra-fine (microns) to thicker gauges, depending on the application.
