MATERIAL TO BE WELDED

It is recommended for use in the production of electrical motors, dynamos and the joining of copper pipes in ship building and offshore industries. It is extensively used in refrigeration, air conditioning and heat-exchanger components for fluxfree brazing of copper pipes and tubes. It is also used for joining copper in electrical engineering applications. Not suitable for brazing iron-containing materials like carbon, stainless steel, or materials with a nickel content as the phosphorus within the filler will form brittle compounds at the joint. For brazing copper to copper no flux is needed. 

A carriage charge is applied to orders, for standard 1-2 day shipments to mainland destinations within the United Kingdom. Other destinations and premium services are available but subject to additional freight charges.
