SHANGHAI, Sept. 20 (SMM) –In the brass market, despite significant declines in SHFE copper prices, American West brass price declines were limited last week, only falling to USD 5,600/mt from USD 5,750/mt, since market offers were mostly decided by market supply and demand. Importers’ buying interest increased following brass price declines. Besides, as markets generally believed there would be limited downside room for brass prices in the future, speculative activities increased, which helped improve market transactions compared with the previous week.
