After heating, molten solder is drawn into a capillary gap between the metals to be joined.</p><p>A liquid low temperature Solder flux is also available for use with the above alloys</p><p>Soldering differs from brazing in that the filler metals employed have melting points of less than 450  C. Brazing filler metals have melting points above 450  C.</p><p>Soft solder</p>
