10、e principles underlying soldering of aluminum are identical to those that make met- allurgical bonding o f other metals possible. After aluminums tough protective oxide coat- ing is removed, the soldering o f aluminum proceeds along lines similar to those used with other metals, utilizing essentiall
11、y the same techniques and equipment. Properly made, aluminum joints are long lasting, gas tight and strong. Depending on the solder chosen, aluminum joints can be as strong as the metal joined, When tested, these joints fail at the base metal. Aluminum i s joined by soldering when many joints are to
12、 be made simultaneously and economically; when nearby material precludes the higher heats o f brazing and welding: when component distortion must be avoided; when temper loss is to be held to a minimum; when equipment investment funds are limited; and when rapid field repairs with hand-held tools ar
13、e needed. Soldered aluminum joints are widely used in spacecrafi, electronics, electrical power plants and power lines, household goods, refrigeration systems and air conditioning. The list of current and fiture solder applications is virtually endless. Library of Congress Catalog Card Number 74-1 7
