March 15 (Reuters) - The Australian unit of U.S.
aluminium producer Alcoa Corp AA.N said on Wednesday the
output at its Portland smelter in Victoria would be reduced to
about 75% of its total capacity of 358,000 metric tonnes per
year, citing instability and production challenges.
Australia's Alumina Ltd AWC.AX owns a 40% stake in Alcoa
Australia, which holds a 55% stake in the Portland Aluminium
joint venture.
