Silver alloy solder is used to join metal parts together by melting and solidifying. The addition of silver to the solder alloy improves its strength, electrical conductivity, and resistance to corrosion, making it suitable for a wide range of applications, such as in electronics, plumbing, jewelry making, and brazing. It is commonly used when a strong and conductive joint is required, and where the joint must withstand high temperatures and corrosive environments. feihongalloys.com
