Three-month copper on the London Metal Exchange rose as much as 0.7% to $10,040, its highest level since February 2011 when the contract hit a record high of $10,190 a tonne.
However, copper prices were down 0.1% at $9,962.50 a tonne as of 0710 GMT as the dollar rebounded, making greenback-priced metals more expensive to holders of other currencies.
Aluminium advanced 0.4% to $2,438 a tonne, nickel increased 1.1% to $17,855 a tonne and tin climbed 1.6% to $29,465 a tonne.
The U.S. economy is growing at its fastest rate since the early 1980s, while British manufacturing activity grew at the fastest pace in almost 27 years last month.
