METALS-Weaker U.S. dollar pushes copper into the black

(Updates prices)

SYDNEY, July 21 (Reuters) - A weak dollar helped lift copper prices above $6,000 a tonne in Asian trading on Friday, erasing an overnight dip and setting the stage for a strong start to the London market.

The dollar index, which tracks the greenback against a basket of six major rivals, was priced near its lowest level since August 2016.

A hobbled dollar coupled with a positive Chinese outlook for metals demand on Monday lifted copper above the psychologically key $6,000 mark for the first time since March 2.

A weaker dollar makes U.S. dollar-denominated commodities such as copper cheaper for investors using other currencies.

"The weak dollar will bring out buyers, some of whom might otherwise stick to the sidelines," a trader in Perth said.
