Innovation & Technology Offer

A UK company offering a low temperature soldering alloy for joining carbon materials seeks partners to implement their solution for a commercial agreement with technical assistance or to join an R&D consortium for a research cooperation agreement.

Country of Origin: United Kingdom
Reference Number: TOUK20170223001
Publication Date: 23 February 2017


A UK based company has developed a low-temperature soldering alloy for joining of carbon materials to one another or dissimilar materials such as metals. The solder produces mechanically strong and electrically conductive bonds with no need of flux. The company seeks partners who wish to use the solder in their product for a commercial agreement with technical assistance or a research  cooperation agreement to join a consortium for R&D projects in European calls for grants e.g. H2020


The unique properties of graphitic materials, including low density, high melting temperature, excellent thermal conductivity, resistivity to corrosion and erosion as well as great mechanical performance in wide range of temperatures might render them unrivalled candidates for the applications in many areas of industry. However, the difficulty of joining of these structures together or to other materials such as metals has always been one of the major constraints limiting the application of classic carbon materials and nowadays becomes an obstacle for the potential use of nanostructured carbon materials.

The patented soldering solution developed by this UK company is tin-based, lead-free and is applied at low-temperatures enabling the joining of various carbon materials including carbon fibres or carbon nanotube fibres in both carbon-carbon and carbon-metal arrangements. The soldering of carbon materials may be performed in air, at temperatures in the range from 300°C to 450°C with the use of classic soldering iron. Currently the main alternative to this process is the brazing process (800-1200°C) which may lead to the combustion of carbon materials, in particular nanostructured ones, as well as is responsible for the stress concentration during cooling of the joint made of materials with considerable difference of thermal expansion coefficients.

Solder developed by this UK company offers a patented tin based, lead –free, low temperature, flux less joining of carbon-carbon or carbon-metal.

The solder can be purchased on line in 1m lengths and larger quantities can be purchased by contacting the company. Full data sheets for the solder are available.

The company is happy to work with businesses looking to find better ways to carbon and can assist in the process of research and development of a solution.
The company seeks partners interesting in incorporating this new bonding technique into their designs either carbon-carbon or carbon-metal for a commercial agreement with technical assistance.

The company is also interested in being involved in R&D projects as part of a consortium for a research cooperation agreement.


Advantages and Innovations

This unique soldering solution overcomes the difficulties of joining graphitic structures together or to other materials such as metals. It offers:

a) The ability to exploit the attractive properties of graphitic materials in more applications

b) No flux is required

c) The soldering can take place in air at temperatures between 300 and 450 degrees meaning no expensive equipment is needed – a standard soldering iron is all that is required

d) The solder offers excellent wetting of carbon materials ensuring carbon to carbon or carbon to metal bonds can be achieved

e) The solder offers fast formation of mechanically strong bonds which are electrically conductive simultaneously.

f) The solder is lead free.

g) The company has a highly qualified technical team with many years of research experience in materials science.

Stage Of Development

Already on the market

Requested partner

The company seeks partners for a commercial agreement with technical assistance in industry looking to find alternative solutions to joining carbon materials such as carbon fibres or carbon nanotube fibres either to other graphitic materials or to metals and who need to bring in expertise to achieve this.

The company is heavily R&D focused with a strong pedigree of research from the University of Cambridge and hence would also like to work on R&D calls for grants such as Horizon 2020 as part of a consortium for a research cooperation agreement.
