Copper futures ended lower on Tuesday, pressured by a stronger US dollar, which tends to weigh on foreign demand for the dollar-denominated asset and rising inventories. However, some losses were capped by better-than-expected industrial production data from China. China's industrial output rose 7 percent in April, above forecasts for a 6.3 percent increase and up from a seven-month low of 6 percent in March.
Copper futures for July delivery fell 1.2 percent to settle at $3.056 a pound on the Comex metals division of New York Mercantile Exchange. While, copper on the London Metal Exchange closed down 1.1 percent at $6,808 a metric ton
