Aluminium Solders
Low-melting zinc aluminium hard solder for soldering aluminium and Al alloys, copper and copper alloys, as well as steel.
Whether in the area of repairs or in the new production of heat exchangers, copper/aluminium pipework or in car manufacturing, the low working temperature of 450°C allows you to produce top quality solder joins with Silox® S 7 W.
You can process Silox® S 7 W as wire or as a moulding using the flame soldering process or with induction soldering.
Ögussa solid solders and BrazeTec solder pasts for soldering aluminium can be used both for soldering in the air or in an inert gas atmosphere in a furnace.
