SHANGHAI, Jul. 1 (SMM) - Spot aluminum largely traded between RMB 13,340-13,360/mt in Shanghai on Tuesday, a discount of RMB 80-100/mt over SHFE 1407 aluminum contract. Mainstream traded prices were RMB 13,350-13,360/mt in Wuxi, and RMB 13,370-13,380/mt in Hangzhou. Rising SHFE aluminum allowed sellers to raise offers, and buyers became more willing to buy now that liquidity crunch has eased. This pushed prices up.
