US copper futures slipped to a 6-month low early Friday, pulled down by a wave of dollar-induced liquidation in the broader commodity complex. Copper for September delivery fell as low as $3.3075 a lb on the New York Mercantile Exchange's Comex division, the contract's lowest price point since February 7.
By 10:27 am EDT (1427 GMT), it was trading down 9.30 cents or 2.7 percent at $3.3250. Comex estimated futures volumes at 15,362 lots by 10 am.
