Thessco Limited is one of the world's largest manufacturers of silver brazing alloys, metal joining products and industrial silver alloys.

All Thessco alloys are produced to the highest British and other international quality standards, with precise manufacturing control both chemically and metallurgically.

Our own silver refinery produces the highest purity silver, internationally accepted on the London Bullion / Association as "Thessco Brand 999 and 9999".

The manufacture of precious metal alloys has been carried out on our site in Sheffield, England, since 1760 and our unique historical experience, coupled with modern computer controlled manufacturing processes, ensures the production of all our materials to the highest international standards.

Special alloys can be produced to customers' individual requirements if necessary, but our extensive range of standard alloys and sizes meet most requirements.
