LONDON: Copper prices held on to gains on Tuesday amid signs higher demand from China and Europe where manufacturing activity picked up in May, while potential supply disruptions also supported.
Benchmark copper on the London Metal Exchange was barely changed at $10,240 per tonne by 1100 GMT after a choppy early session.
Manufacturing in Europe expanded at record pace in May while factory activity in top metals consumer China expanded at the fastest pace in a year in May due to booming domestic demand.
Copper, mainly used in the power and construction industries, is seen as a sensitive gauge of the health of the global economy.
"You have very favourable fundamentals in metals, with economies opening up again and demand rebounding," said independent consultant Robin Bhar, adding that prices could consolidate for a period of time.
But some analysts warned that copper, which rocketed to a record of $10,747.50 in May, had risen too far and a pullback was warranted.
"I'm surprised that copper hasn't corrected further and longer. A correction is strongly needed," said Commerzbank analyst Daniel Briesemann.
