Aluminium Corporation of China Daye Plate & Strip Co. Ltd. (Chinalco Daye) said that it has developed high precision copper strip that could be used in production of 3G communication cable. Chinalco Daye has a designed capacity of 60,000t of high precision copper sheet and strip, and 73,500t copper strip slab. The company produced 2,000t 5PPM high grade oxygen free copper casting ingot from March to July this year.
Daye Nonferrous Metals Company, China's fifth-biggest copper producer, is likely to expand copper mine resources after a 1 billion yuan ($145.92 million) cash investment from Yangtze Power Co Ltd.
Daye Nonferrous Metals Co. announced the commissioning of its copper fabrication project on 4th August 2011. The development of the project required an investment of RMB2.1B and is set to reach a production capacity of 300,000t/y.
On August 19th, Chinalco began work on its 300 ktpa copper semis facility in Kunming, Yunnan Province. The company's three existing processing sites, Chinalco Luoyang Copper, Chinalco Shanghai Copper and Chinalco Daye Copper Sheet & Strip, account for around 28% of China's total copper sheet and strip capacity, with a combined total of 130 ktpa, and 220 ktpa of expansions under construction. The new facility, with total investment of RMB2 billion, will comprise a 100 ktpa sheet and strip facility and a 200 ktpa wire and rod facility.
