March 25 (Reuters) - Nickel on the Shanghai Futures Exchange surged by as much as its 20% trading limit on Friday on persistent worries about supply, putting it on track for its biggest weekly gain on the Chinese bourse since the 2015 launch of a nickel contract there.

Shanghai's benchmark nickel contract climbed to as high as 269,940 yuan ($42,445.40) a tonne, advancing for a third straight session and mirroring the metal's steep rise this week on the London Metal Exchange.

LME nickel prices soared to record highs above $100,000 a tonne on March 8, after which trading was suspended for six sessions, amid large purchases by China's Tsingshan Holding Group to reduce its short positions in the metal used to make stainless steel and electric vehicle batteries.

Concerns over nickel supply in the wake of the Ukraine invasion by Russia, which accounts for about 10% of the world's nickel supply, and possible short-covering continued to underpin the metal, analysts said.

FUNDAMENTALS

* Three-month copper on the London Metal Exchange was up 0.3% at $10,383 a tonne by 0224 GMT, while the most-traded May copper contract on the Shanghai exchange slipped 0.1% to 73,570 yuan a tonne.

* Russia might look to its giant neighbour to replace Australian alumina supplies cut off by sanctions, but Chinese aluminium smelters need all the feedstock they can get and may be worried about secondary sanctions from the West, industry analysts say.

* MMG Ltd said on Thursday it has secured approval from Peru's Ministry of Energy and Mines to expand its Las Bambas copper mine despite ongoing outrage from local indigenous communities.

* The Serbian arm of China's Zijin Mining plans to stop production at its copper smelter for three months to carry out a planned work.
