LONDON: Aluminum hit a three-week low on Monday and copper also fell, weighed by a stronger dollar and weak Chinese industrial output.

Three-month aluminum on the London Metal Exchange closed 1.2 percent lower at $1,542.50 a ton after touching $1,536, the weakest since Feb. 19.

LME copper shed 0.5 percent to end at $4,946 a ton, after touching a four-month peak of $5,059 on March 4 and gaining 1.6 percent in the prior session.
