SHANGHAI, Jul. 4 (SMM) – Traded prices of spot aluminum in Shanghai were mainly between RMB 15,690-15,720/mt Wednesday, with spot discounts over the SHFE aluminum prices at RMB 20-50/mt, and low-iron aluminum was traded between RMB 15,800-15,820/mt in Shanghai. SHFE aluminum prices gapped higher influenced by the surging LME aluminum prices overnight, but gave back some gains due to a lack of upward momentum. Downstream enterprises reacted mildly to the price increases, dragging down spot aluminum prices. Cargo holders were eager to sell goods. The diverged attitude of suppliers and buyers left transactions sparse.
