May 23 (Reuters) - Most nonferrous metals declined on Tuesday, as a firmer dollar made greenback-priced metals more expensive to holders of other currencies.

The most-traded July copper contract on the Shanghai Futures Exchange declined 0.8% to 64,600 yuan ($9,345.93) a tonne by 0409 GMT, while three-month copper on the London Metal Exchange rose 0.1% to $8,135.50 a tonne.

The dollar touched a six-month high against the yen, as expectations grew that U.S. interest rates will remain higher for longer and as the debt-ceiling impasse kept risk sentiment fragile.

LME aluminium eased 0.1% to $2,260.50 a tonne, nickel declined 1.1% to $21,180 a tonne, zinc eased 0.3% to $2,425.50 a tonne, lead decreased 0.2% to $2,082.50 a tonne, while tin rose 0.2% to $25,000 a tonne.

SHFE aluminium declined 0.5% to 18,030 yuan a tonne, nickel eased 0.3% to 166,140 yuan a tonne, zinc dropped 1.5% to 20,085 yuan a tonne, tin decreased 1.5% to 196,510 yuan a tonne and lead shed 0.6% to 15,295 yuan a tonne.

Concerns about China metals demand also weighed on sentiment.

Rising copper inventories in LME exchange warehouses weighed on London prices, while declining stockpiles in SHFE warehouses provided some support to China prices.
