Tungsten Fine Wire Filament 0.25 mm 2m Roll by PHasz

Description

Product Overview

The PHasz tungsten fine wire filament is engineered for high‑performance industrial applications where material purity, dimensional accuracy, and mechanical resilience are critical. Each roll contains a continuous 2‑meter length of wire with a tightly controlled diameter of 0.25 mm, meeting the stringent tolerance requirements of aerospace, electrical, and thermal management sectors. The wire is produced from tungsten with a purity level of 99 % or higher, ensuring consistent conductivity and resistance to oxidation even under extreme temperature conditions. Its inherent high melting point—exceeding 3,400 °C—provides unmatched thermal stability, while the material’s excellent plasticity allows for precise forming, bending, and shaping without fracture. The product is supplied in a single roll, with the reel color varying between batches, reflecting the random nature of the manufacturing process. This filament is a versatile component for heat sinks, rudder balance weights, switch contacts, circuit breakers, and other critical contact materials where longevity and reliability are paramount.

Usage

Designed for demanding environments, this tungsten filament excels in applications that require both high thermal resistance and mechanical flexibility. In aerospace engineering, the wire is used to fabricate balance weights for control surfaces, where its density and stability contribute to precise maneuverability. Electrical instrumentation benefits from the filament’s low resistivity and stable performance, making it an ideal choice for contact points in high‑voltage switches and circuit breakers that must endure repeated cycling without degradation. Thermal management systems, such as heat sinks for power electronics, rely on the filament’s ability to dissipate heat efficiently while maintaining structural integrity under continuous operation. Additionally, the wire’s large adsorption area and ionization properties make it suitable for specialized scientific equipment, including vacuum chambers and ion sources. Users can easily cut, bend, or coil the wire to fit custom designs, thanks to its superior ductility, and the material’s resistance to oxidation ensures long service life even in harsh chemical environments.

FAQ

What is the recommended method for cutting the tungsten filament?

We recommend using a fine‑toothed wire cutter or a precision rotary tool with a carbide blade. Apply steady, even pressure to avoid deforming the wire. For the cleanest cut, cool the wire with compressed air or a light mist of coolant to reduce heat buildup during the cutting process.

Can the filament be used in vacuum environments?

Yes, the high purity of the tungsten material makes it well‑suited for vacuum applications. Its low outgassing rate and resistance to oxidation ensure stable performance in high‑vacuum chambers, making it ideal for scientific instruments and space‑grade components.

How does the filament perform under repeated thermal cycling?

The filament’s high melting point and robust crystalline structure allow it to withstand repeated heating and cooling cycles without cracking or losing mechanical integrity. This durability is why it is commonly selected for applications such as heating elements and thermal probes that experience frequent temperature fluctuations.

Is the filament compatible with standard soldering techniques?

While tungsten is not typically soldered due to its high melting point, it can be joined using specialized high‑temperature solder alloys or diffusion bonding methods. For most applications, mechanical fastening or crimping is preferred to maintain the filament’s structural properties.

What warranty or guarantee does PHasz provide for this product?

PHasz offers a 12‑month limited warranty covering material defects and dimensional inconsistencies. If the filament does not meet the specified purity or diameter tolerances, we will replace the affected roll at no additional cost, provided the issue is reported within the warranty period.
