Aluminium manufacturer Alcoa Inc says it lost $US2 million ($A1.97 million) in the second-quarter as revenue dropped due to weaker prices and pockets of declining demand in the slowing global economy.
Alcoa on Monday posted break-even earnings per share, compared with 28 cents per share, a year ago. Excluding one-time items, Alcoa's earnings were 6 cents per share.
Revenue fell 9 per cent to $US5.96 billion.
Analysts surveyed by FactSet expected 5 cents per share on revenue of $US5.83 billion. Such items typically exclude one-time items.
The aluminium industry has faced challenges as some European countries slide into recession and growth slows in the US and China.
Alcoa's performance reflects broader economic trends because aluminium is used in a wide range of products from automobiles to beverage cans.
