Abstract: This paper introduces the status and significance of producing aluminum -titanium alloys by adding titanium oxide directly in aluminum electrolysis cell. The master alloys with 0.3% -0.6% titanium by adding titanium oxide in 200KA cell are prepared. Analyses on technological indexes, such as selecting technological parameters, optimizing titanium oxide adding technology, current efficiency of the aluminum electrolytic are performed. The results show that the technology is feasible and cost-effective.
