carrs No 179 Solder

Part Number: C1003.
Form: Wire.
Quantity: Approx 2 metres
Melting Point: 179°C.
Lead Free: NO
Flux: Dependent on metals being joined.
Constituents: Tin/Lead/Silver.
Usage:
This is a specialised solder for aluminium and its alloys – Mazak, etc. and is used with Grey Label Flux. It has only about half the strength of a tin/lead solder and will fuse with almost any metal provided that the right flux has been used. It has a high surface tension so makes thick joints with large fillets. As aluminium soaks up a lot of heat, use a higher wattage iron than for brass. Soldered aluminium is highly susceptible to corrosion, therefore it is important to seal all joints from the atmosphere within an hour or so of making them. ELEXTROFIX is ideal for this.
