What is tungsten?
As the heaviest common, naturally occurring metal, tungsten is ideal for use in applications where weight is required in a small space. It is non-toxic, non-radioactive, recyclable and dimensionally stable at high temperatures, and is used in all manner of functions from aerospace engineering to radiation screening.
In its pure form tungsten can be brittle and not easily machinable. With a melting point in excess of 3,000°C it also cannot be cast, extruded or easily formed. Using our expertise in powder metallurgy techniques we produce Wolfmet tungsten in the form of a metal matrix composite. This can then be machined by conventional techniques to produce very complex and exacting parts.
Wolfmet tungsten alloy consists of 90-97% tungsten depending on the grade. It retains the unique density and radiation shielding capabilities of pure tungsten while at the same time being easier to machine to tight tolerances. It is the only metal that we make, and is manufactured using non-conflict sourced tungsten powder at our facility in the UK.
With an acknowledged reputation as one of the world’s most experienced tungsten specialists, Wolfmet manufactures tungsten alloy components to the highest specifications and quality standards. Our processes are ISO 9001 and ISO 14001 accredited, while for aerospace applications they are also AS9100 approved.
Because tungsten has the highest melting point of any metal, there isn’t a vessel that is capable of holding the molten liquid. Instead, the Wolfmet team carries out a powder metallurgy process which plays a significant role in the quality of the finished product. From accurately weighing raw materials and applying exacting temperatures at different stages, to precise machining and extensive quality control systems, attention to detail is key to ensuring finished tungsten alloy components meet the standards required by our customers.
Selective laser melting
Wolfmet now offers additive manufacturing for pure tungsten components. Selective laser melting (SLM), comprises a high powered laser which fuses successive layers of tungsten powder until a complex component is produced.
Machined parts and assemblies
We have three, four and five-axis machining and twin spindle turning utilising live tooling. This allows us to machine complex parts efficiently and in volume.
We are also skilled at integrating Wolfmet tungsten alloy parts with other metal components, such as steel and aluminium. For example we have produced isotope containers with 15 individual parts, including locking mechanisms and multiple seals and syringe shields with lead glass windows.
