Johnson Matthey Metal Joining has manufactured brazing and soldering materials since 1917 and  has marketed them since 1932. Over these years Johnson Matthey carried out a great deal of development and research. Although old in its format this work is still technically valid. Johnson Matthey are therefore releasing any documents that are no longer commercially sensitive for wider use.

'The knowledge that we have accumulated, combined with the experience of our technical teams, allows us to offer the best solutions for joining metals'

Cadmium-free Brazing Information Campaign

REACH is a European Union regulation concerning the Registration, Evaluation, Authorisation and restriction of Chemicals. It came into force on 1st June 2007 and replaced a number of European Directives and Regulations with a single system.

Under REACH legislation Belgium’s Federal Ministry of Health, Family and Environment assessed cadmium and its compounds in 2007; a 2,000 page report was produced and approved by member states in 2008. It recommended a ban on cadmium in a number of applications including brazing.

When Johnson Matthey learnt of this report in 2008 we started to inform our remaining customers using cadmium containing filler metals to encourage them to start using cadmium-free products.

These are some of the communications made with customers and users of cadmium containing filler metals between 2008-2012.
