BEIJING, May 27 (Reuters) - Prices of aluminium futures in Shanghai gained on Monday, supported by a strong price rally in key raw material alumina and robust demand.

The most-traded July aluminium contract on the Shanghai Futures Exchange advanced 0.4% to 20,960 yuan ($2,894.03) per metric ton as of 0134 GMT.

The London Metal Exchange is closed on Monday for a bank holiday.

The most-traded SHFE alumina contract gained 8.3% last week, boosted by speculative trading given limited supply and rising demand expectations.

The most-traded July alumina contract climbed 0.7% to 4,106 yuan per ton.

Also aiding prices was firm demand, especially the rapid increases in consumption from solar and electric vehicles sectors, analysts said.

SHFE copper little moved at 83,830 yuan a ton, nickel added 0.8% to 153,350, zinc was stable at 24,625 yuan, lead rose 0.7% to 18,605 yuan, while tin decreased 0.4% to 27,370 yuan.
