SHANGHAI, Jun. 18 (SMM) - Spot aluminum largely traded between RMB 13,280-13,290/mt in Shanghai and Wuxi on Wednesday, a discount of RMB 90-100/mt over SHFE 1407 aluminum contract. Mainstream traded prices were RMB 13,290-13,300/mt in Hangzhou. SHFE front-month contract has been moving sideways for several days, so wait-and-see sentiment among downstream producers faded, pushing the low-end price up.
