Tin prices gain 7.4 percent this week

Tin prices added 7.4 percent to $9,750 per tonne after going as high as $9,950 per tonne earlier in Friday’s session. The price gains came after several small smelters in Indonesia were put out of production after three of the facilities were closed by police for operating without proper permits. The closures spurred concerns about supply interruptions. Meanwhile, prices for lead were up 5.4 percent to $1,490 per tonne this week after hitting a record high $1,514 per tonne during the session on Friday, also on supply disruptions.

Nickel closed at a new record higher of $31,100 per tonne Friday, a gain of 5.6 percent during the week as demand was strong but London Metal Exchange warehouse inventories dropped to only 2,130 tonnes available for delivery. Elsewhere, copper added 0.3 percent this week to $7,485 per tonne, aluminium was 1.7 percent higher to $2,635 per tonne, and prices for zinc were 5.1 percent higher over the week to $7,485 per tonne.
