AlumWeld CL is a well-known filler metal for soldering aluminium and other metals. The solder has high strength, conducts electricity and heat. It is also corrosion resistant. Particularly suitable for repairs, as the fluidity of the alloy during soldering depends on the temperature. This makes it possible, for example, to seal a hole without pouring alloy into it. The package contains 1 m of solder with a diameter of 2.5 mm. This is sufficient for several metres of continuous joint.

Soldered materials:

aluminium and its alloys,
galvanised steel,
steel and brass (AlumWeld Blue flux required).

Soldering temperature 430-470 °C.
Good thermal and electrical conductivity.
Corrosion resistance.
High strength.
Easy machining (drilling, milling, threading, grinding).

Fields of application
The solder is excellent for repairing radiators, air-conditioning components, as well as cracked covers and housings (e.g. alternator, pump, oil sump, etc.). Using a mould (e.g. made of clay), it is possible to fill larger cavities. It is also possible to solder aluminium constructions and make small castings.

Soldering is very simple. It successfully replaces welding, especially when the use of a welder is not possible. Connections are made with an ordinary torch, e.g. propane-butane. Simply heat up the object to be brazed, apply AlumWeld filler metal so that it melts from its heat, place the joint and leave it to cool down.
