brazing




A process in metallurgy whereby two pieces of metal are joined using a nonferrous alloy (usually of copper) of lower melting point. The bonding alloy is either preplaced or fed into the joint as the parts are heated. The process is akin to soldering but is performed at higher temperatures (about 1000 K). Brazed joints are very reliable and are used extensively in the aerospace industry.
