BEIJING, Dec 20 (Reuters) - London copper prices held steady above $6,200 a tonne in early Asian trade on Friday, heading for their fifth straight weekly gain on easing U.S.-China trade tensions and an improving demand outlook in top consumer China. The metal widely used in construction and power is on course to add 1.4% this week and is up 4.2% so far this year.

* ALUMINIUM: Shanghai aluminium rose for a fourth straight day, by as much as 0.6% to 14,245 yuan a tonne, the highest since Sept. 16, as low inventories raise supply concerns. LME aluminium added as much as 0.4% to $1,804.50 a tonne, the highest since Nov. 11.
