SHANGHAI, Jun. 20 (SMM) – Traded prices of spot aluminum in Shanghai were between RMB 15,720-15,740/mt Wednesday, and low-iron aluminum was traded between RMB 15,790-15,810/mt in Shanghai. SHFE aluminum prices fell alone when other base metals increased, dragging down spot aluminum prices. Cargo holders were not willing to move goods at low prices, causing spot premiums to expand to RMB 50/mt with mainstream traded prices hitting a new low of the year. However, transactions were limited, and both sellers and buyers waited on the sidelines.
