Brazing and soldering make use of silver’s high tensile strength and ductility to create joints between two metal pieces. Brazing takes place at temperatures above 600°C, while soldering takes place at temperatures below 600°C. Silver scrap can be used in brazing and soldering because these processes do not require very pure silver. Brazing and soldering produce tight joints for everything from heating and air conditioning vents to plumbing. Silver’s antibacterial properties and non-toxicity to humans make it a great replacement for lead-based bonds between water pipes.
