Technology was developed for manufacture of SAP, possessing the ability to be welded by the method of fusion, and also technology of its argon-arc welding. Of all existing aluminum alloys, sufficient strength at a temperature of 350 - 5000 0 can be preserved only by material from sintered aluminum powder SAP, the strengthening phase in which is oxide of aluminum. basic initial product for obtaining SAP is finely-dispersed aluminum powder which is obtained by atomization of liquid aluminum with compressed air, with subsequent crushing in ball mills in an oxidizing atmosphere.
