Tungsten semi-finished products and machining

Tungsten semi-finished products and machining: buy tungsten rods, rods, wire, foil and plates from the experts.

We process your tungsten components according to drawings by milling, turning, grinding and eroding from the first prototype to series production.

Editing Tungsten:

Machining tungsten presents some challenges. Tungsten or tungsten alloys are brittle at room temperature and ductile at elevated temperatures. The brittle-ductile transition temperature is also taken into account during machining. In most machining processes, machining takes place at temperatures above the transformation temperature.

Tungsten alloys bring some advantages in machinability. We mainly use lanthanum oxide, cerium oxide and potassium for this. Tungsten alloys not only have the advantage that they are easier to machine, the recrystallization temperature and thus the ductility also increase - which in turn increases the strength.

In order to support you in your project as quickly as possible, we have common rods, rods, foil, wire and plates as semi-finished products in stock. Buy tungsten products from the experts and convince yourself of our service, from advice to delivery.

Crucibles, cathodes, electrodes made of tungsten are mostly customer-specific special products, which we can also produce for you promptly according to drawings.

Tungsten machining according to drawings, from prototype individual parts to series production, CNC-manufactured.

The processing of tungsten brings with it some challenges, especially if you need fine, high-tolerance contours on your components. Our customers from aerospace, mechanical engineering and special plant construction value our many years of know-how and our consulting competence in tungsten processing.

In addition to processing high-purity tungsten (99.99%), we can also manufacture your component in a tungsten alloy of your choice - incidentally, tungsten alloys have different material advantages.

We would also be happy to support you in your next project on the subject of tungsten processing with one of our numerous manufacturing technologies.

Tungsten rod, bars and electrodes in different dimensions and surface finishes according to customer requirements.

Tungsten surfaces can be roughly divided into 3 categories:

- Black surface (scale not removed)

- Surface cleaned with alkali (scale is removed)

- Surface ground (scale was removed mechanically)

Do you need tungsten rods with a high degree of accuracy? No problem, we individually grind each tungsten rod according to your specifications.



In addition to high-purity tungsten 99.98%, we also offer all tungsten rods as alloys:

Wolfram Rhenium (WRe), (WRe5), (WRe26)

Tungsten foil and sheet in different dimensions and surface qualities according to customer requirements.

Compared to tungsten wire and tungsten rods, the surface of tungsten foil is always bright due to the machining process.

The main challenge in rolling tungsten foil is the toughness of the material. Finding the right process parameters for reproducible manufacturing processes, especially with very thin foils, requires many years of knowledge, suitable personnel and suitable machines. If these requirements are not met, the quality differs greatly from manufacturer to manufacturer, especially in the case of tungsten foils.

Do you need tungsten foil with very precise thickness tolerances? No problem, we roll the tungsten foil you need with a thickness tolerance of just a few micrometers.

In addition to high-purity tungsten 99.98%, we also offer tungsten foils in the following alloys:

Wolfram Rhenium (WRe), (WRe5), (WRe26)

tungsten properties

Tungsten possesses unique properties as a high-performance material, including

a melting point of 3410 ° C. Tungsten also has a very low vapor pressure at high temperatures and a low coefficient of thermal expansion. Thus, tungsten finds application in a variety of high-temperature products and processes, such as glass-to-metal sealing parts and support parts for lighting and electronics, silicon rectifier bolt mounts, and high-temperature furnace components.

Historically, tungsten-rhenium alloy wire and rod were manufactured primarily for the thermocouple market, but recent demands for high temperature structural components have forced the development of new processing techniques for tungsten-rhenium and tungsten-rhenium with hafnium carbide. The addition of hafnium carbide is known to increase the strength of refractory metals. The applications for these materials are in the medical, aerospace, furnace and heat treatment industries.

Tungsten-Rhenium alloys with a melting point of 3050°C and a recrystallization temperature close to 1900°C are used in aerospace, temperature measurement and friction stir welding applications.
