Copper Nears Record High on Tight Global Supply; Aluminum Surges

Copper extended gains above $14,000 a ton, inching toward a record set in late January, as supply risks mount from mine disruptions around the world. Aluminum surged to the highest in more than four years.

The red metal rallied for an eighth session to touch $14,196.50 a ton on the London Metal Exchange, close to its all-time high of $14,527.50.
