Alloying Addition For Alloying Manganese To Aluminum
US Patent:
4171215, Oct 16, 1979
Filed:
Jul 3, 1978
Appl. No.:
5/921166
Inventors:
Charles E. Dremann - Phoenixville PA
Assignee:
Foote Mineral Company - Exton PA
International Classification:
C22C 2200, B22D 2308
US Classification:
75 05B
Abstract:
Manganese is alloyed into aluminum using a solid compact prepared by blending finely divided particles comprising beta manganese with aluminum particles and then compacting the mixture into a readily useable form such as a briquette. The resultant briquette provides rapid dissolution of the beta manganese in the aluminum and improved manganese recoveries. The beta manganese may be prepared by heating manganese to 1305. degree. -1990. degree. F. followed by water quenching and crushing to obtain a product of controlled particle size having a reduced percentage of fines.
