Shanghai copper rises

Base metals mostly traded mixed in Asia as investors digested bearish Chinese and US economic data and awaited monthly US nonfarm payrolls data due out later on Friday. The most-traded copper contract on the Shanghai Futures Exchange closed 0.18 percent higher at 50,420 yuan ($7,504.65) a tonne on Friday.
ShFE aluminium slipped 0.31 percent. ShFE lead and nickel ended 0.54 percent and 0.38 percent higher respectively, while tin finished 0.80 percent up. The US Institute of Supply Management manufacturing index fell more than expected overnight, while growth in China's services sector slowed in July, according to the Caixin/Markit services purchasing managers' index. China's crackdown on its bloated aluminium industry is driving up the share price of the country's major producers and raising the spectre of a tighter global market that could buoy prices.
