CuP Alloys (Modelling) Ltd and CuP Alloys Ltd
Silver Solder and Brazing Material Specialists

Welcome to CuP Alloys - two companies that sell nothing but silver solder and brazing materials.

Both companies are managed by Keith Hale B.Sc. Hons (Metall.). He first entered the brazing market in 1969 and has been a silver soldering specialist for some of the leading european suppliers including Johnson Matthey and Engelhard/Sheffield Smelting Co .

CuP Alloys are totally committed to providing the best value and service, be they large or small users. Their product ranges are second to none, matched by the level of technical help available.

CuP Alloys (Modelling) Ltd
retail small packs of silver solder rod, and wire by the metre, as a speciality service. Suitable fluxes are available to cover all applications. Materials are available ex stock and are despatched world wide at very competitive prices. They are ideal for the model maker, amateur silversmith, jobbing engineer, anyone who requires just small quantities by the metre or by the rod.

Other products include firebricks, plates and insulating blankets to use the heat more efficiently and speed up the brazing process.

BS EN 1044

In 1999 "Europe" rationalised the three main standards for silver solder and other brazing alloys, BS 1845, DIN 8513 and NF A- 81 to create this new standard EN 1044.

Silver Solder
All alloys are made using only pure virgin metals to ensure top quality brazing characteristics.
This is particularly relevant to meet the specifications of cadmium free silver solder.

All materials are manufactured in Spain by a company with ISO 9001 accreditation for their quality management system relating to the manufacture of brazing materials. (Certificate No. E202200)

Some larger and better known suppliers do not have that approval for manufacturing alloys.
Check their websites!
Like CuP Alloys they are distributors and have the same source of supply as we!

Copper Brazing Alloys
Again all materials are made using only pure virgin metals to ensure top quality brazing characteristics.
They are used for the fluxless brazing of copper in air. Equally they can be used to join copper alloys when used in with a flux.
