MANILA, Jan 25 (Reuters) - Nickel prices tumbled on Tuesday on profit-taking, with the Chinese futures market hitting the session's 8% lower limit after a blistering rally to record highs, as caution prevailed ahead of the U.S. Federal Reserve's meeting.

The most-traded March nickel contract on the Shanghai Futures Exchange dropped to as low as 163,460 yuan ($25,823.88) a tonne.

Nickel futures in top consumer China scaled fresh peaks above 180,000 yuan on Monday, supported by concerns over low inventories at exchanges and robust demand prospects.

Three-month nickel on the London Metal Exchange was down 1.3% at $22,100 a tonne, as of 0300 GMT, extending losses after a 6.8% slump on Monday.

The metal used to make stainless steel and chemicals for electric vehicle batteries touched $24,435 a tonne last week, the highest since August 2011.
