The design of the mould weld cavity, tap hole, crucible etc is different for copper and aluminium joints, and therefore
moulds for copper cannot be used for aluminium and vice versa.
The emphasis in this catalogue is on Copper type connections.
Copper joint selections are made from see THE JOINT CATALOGUE.
A short section is given to Aluminium, and selections are made from see THE JOINT CATALOGUE. As aluminium is a complex material it is
recommended that our Factory be contacted on the application.
Special weld metals are formulated for “special” types of joints, cf. High voltage cable joints, large bus bar connections
etc. In each case our Technical Staff will ensure the correct formulation.
The Cu and Al series of weld metals is a deflagration process of metal oxides reacted with aluminium. This exothermic
reaction creates an instant and very high temperature metal pool that is used to metallurgically fuse the conductors
