SHANGHAI, Oct. 12 (SMM) – Spot aluminum was mainly traded between RMB 15,320-15,340/mt in Shanghai on Friday, with discounts between RMB 0-10/mt and premiums between RMB 0-10/mt. Low-iron aluminum was traded at RMB 15,390-15,400/mt. The SHFE 1212 aluminum contract rose slower than other base metals and the current-month contract expanded losses. However, cargo holders held quotations flat with the current-month contract due to dip-buying from downstream producers and middlemen. Trading improved from a day earlier.
