Tantalum is a unique metal used in many specialist applications. Its resistance to chemical corrosion and high melting point make it a desirable choice for
chemical plant equipment and a host of advanced technology applications.
Its electrical properties make it a leading choice for the production of high performance capacitors in critical electronics applications such as airbag deployment systems, brake control systems, and computer control systems in cars. The move towards electric vehicles is creating a stronger demand for higher performance tantalum capacitors which requires tantalum metal powder producers to innovate higher capacitance powders.
In the Metalysis process we are able to control morphology from directly from our chemical processes and produce high surface area metal powders suitable for capacitor use across a range of capacitance criteria.
Being truly vertically integrated, from our own mines in Rwanda through to our refineries in North Macedonia. and to our powder metallurgy facilities in England, we offer a unique solution for our clients.
Tantalum has been plagued by historical supply chain issues, from its reputation as a conflict, or blood mineral, to highly volatile price swings, as much as 400% in some cases, it has led many companies to avoid using tantalum capacitors where possible.
However, we offer something unique.
Not only can we provide a new paradigm in morphological control, carbon impurity limitation and oxygen optimisation, we can offer guaranteed long term price stability and an uninterrupted supply chain.
With over 50% of the global consumption of tantalum being used in capacitors, this is naturally an important segment to us, but our innovation doesn’t stop here.
With tantalum being a notoriously difficult element to alloy with, the Metalysis process allows us to create a new generation of alloys for use in aerospace, nuclear energy, as well as additive manufacturing across a range of powder diameters, both spheroidised and particulate.
We produce:
  • Tantalite concentrates: 20% min. Ta2O5
  • Tantalum pentoxide: Range of oxide powders inc. 99.99% purity
  • Potassium heptafluorotantalate, (K2TaF7): Range of products suitable for certain cap grade feedstock and met grade products
  • Metal Powders: Range of products for AM, met grade, cap grade and high cv cap grade applications. Custom morphologies and surface areas available.
All Metalysis products are compliant with OECD Due Diligence Guidance for Responsible Supply Chains. Learn more about this in our sustainability section.
Titanium is favoured for additive manufacturing for a range of reasons including its corrosion resistance and high strength to weight ratio.
We produce high performance alloy powders for the additive manufacturing sector which are applicable to aerospace, automotive, marine, performance retail goods, and much more besides.
Currently, the additive manufacturing (3D printing) industry is driving titanium demand, growing at ca. 30% per year. Grade 5 Ti-6Al-4V accounts for 50% of titanium powder usage globally.
Our Titanium product family encompasses a wide range of different alloy specifications and compositions, including Grade 5, but also other titanium grades and bespoke alloys.
We can tailor titanium powder size, purity, morphology and its alloying elements producing various sizes down to below 100
μm. The flexibility of product form allows our team to target a range of advanced powder metallurgy manufacturing methods
that reduce material wastage.
Our processes can also produce titanium alloys in the solid state that would be highly complex and expensive to manufacture
using conventional melting techniques. This provides two significant opportunities:
  • The process can produce master alloys or pre-alloyed feed for conventional ingot producers.
  • Metalysis can develop novel alloys with improved performance that will expand the current market for titanium products.
Metalysis works with a range of commercial partners as well as participating in research projects to test the suitability of
titanium powders for new high-end additive manufacturing applications and innovations.
Through tailor made titanium alloys, we can produce specific particle size distributions which lend themselves to given
variations in 3D printing processes, such as selective laser melting, (SLM); electron beam melting, (EMB); or direct metal
deposition, (DMD).
With the properties of scandium as an additive in aluminium, the disruptive nature of a new generation of AlSc alloys is well understood to present one of the most transformative potentials of the new manufacturing economy.
Scandium is typically grouped with the Rare Earth Elements, (REEs), in general reference and, contrary to what this might suggest, is relatively abundant in the earths surface but is spread thinly so is rarely found in singular economically mineable quantities. It is however often associated with tantalum and niobium geology and produced as a by-product.
With various uses in specialist lighting and ceramics, in particular solid oxide fuel cells, the Metalysis process provides for a new shift in primary usage potential, such as vehicle light-weighting and increase usage in aerospace applications.
Just 0.0% – 0.1% scandium in an aluminium alloy significantly protects against corrosion, can decrease the weight of an aircraft by 15% – 20% and substantially improves its fabrication properties.
The production and concentration of scandium in AlSc alloys has been limited by traditional techniques not being able to produce high scandium content alloys. The Metalysis process changes this and is capable of producing a range of simple and complex alloys with high scandium content, ushering in a new era for engineers and designers across automotive, marine, aerospace, and performance goods applications.
With scandium present in the Rwandan mines and other deposits which Metalysis is exploring, significant demand increases are matched by upstream investment and partnerships for supply chain stability.
From our European production facilities, we serve long-term and newly established customer bases in a wide range of end user industries, including aerospace, automotive, FMCG, luxury items, space exploration and multinational metals conglomerates.
The reasons why so many large customers choose to source their bespoke alloys from us is simple: We deliver the highest quality, advanced alloy powders for competitive prices, with the highest regard for environmental footprint.
High Entropy Alloys (HEAs), are an emergent class of alloys, consisting of five or more metals.
Metalysis is creating a new class of HEAs with both refractory and light-weighting alloys; two highly sought after performance characteristics for end user applications in aerospace.
With very little known about higher order systems, HEAs are a relatively new field to material science and the exciting prospects which the Metalysis process presents provide virtually unlimited possibilities.
The Metalysis process allows for solid state alloying to take place which means that elements with mismatched boiling points and/or densities can now be alloyed. HEAs are made for specialist applications and are part of the bespoke alloying production services available at Metalysis.
  • Light-weighting HEAs are considered unique due to significant differences in melting temperatures of c. 1500oC, thus complex to produce
  • The Metalysis process does not involve the melting of metal, avoiding metal vaporization
  • Metalysis’ technology opens up the possibility to develop new classes of HEAs, combining elements from both refractory and light- weighting alloys
The Metalysis HEA product range is a bespoke service with information provided on request.
