FROZEN RIVETS
NEW PROCESS SPEEDS UP AIRCRAFT PRODUCTION
British industry has found a new use for refrigerators—warding off old age in duralumin rivets used in aircraft production. It has been found that if these rivets are stored, after heat-treatment and quenching, at a temperature of about minus 10 degrees F.. they hold on to their working "life” for a longer time than usual. As duralumin, which is being increasingly used for the making of aircraft, tends quickly to “age harden,” this new application of refrigeration will permit aircraft rivets to be stored without any deterioration until they are ready to be used. Special refrigerators, capable of holding 5001bs of rivets at a filling, are now being installed at a number of British factories. This freezing process, which eliminates the need fo» “bracing up” the rivets, will help th« speed-up of British aircraft manuI facture.
