METALS-Copper prices firm on China data expectations

(Updates prices)

SYDNEY, Sept 5 (Reuters) - London copper hit a three-year high on Tuesday on expectations of further signs of a healthy economic outlook for China.

Nickel also found support just shy of Monday's 14-month peak on China's robust industrial outlook, aided by supply-side constraints. China is the world's top user of both copper and nickel.

Over the next few weeks a flurry of data for August is expected to back market expectations for China's growth to taper off only modestly from a solid first half, according to a Reuters poll of analysts.

* LONDON COPPER: Three-month copper on the London Metal Exchange had added 0.5 percent to $6,953.50 a tonne by 0700 GMT, the highest since September 2014, according to Reuters data.

SHANGHAI COPPER: The most-traded copper contract on the Shanghai Futures Exchange rose 1.3 percent to 53,610 yuan ($8,205) a tonne.

* NICKEL: A rally in Chinese steel pushed stainless steel ingredient nickel to an intraday peak of $12,320 a tonne. On Monday, the contract reached its highest since June 2015 at $13,380. ShFE nickel ended 0.8 percent higher.

* MANUFACTURING: Factories across Asia and Europe cranked up production last month as global demand remained strong, confounding expectations growth may have peaked.

* ALUMINIUM DIVIDES: Analysts at Wood Mackenzie said many market observers were skeptical about China's ability to deal with aluminum overcapacity. "But cuts at Weiqiao, the world's largest smelter, shows China's determination to deliver supply-side reforms," it said in a report.

* OVERBOUGHT: Analysts at Commerzbank said copper and other industrial metals were overbought. "Prices have become largely detached from the fundamental data ... the potential for and possible extent of a price correction are increasing every week," they wrote.
