Carbon Products

Carbon material is the main auxiliary material for producing aluminum ingot. It features low content of ash and sulfur, good formability and high strength. Chalco is the largest producer of carbon anode block and semi-graphitic cathode carbon block in China. Chalco’s Shandong branch, Henan branch, Guizhou branch, Guangxi branch, Qianghai branch, Shanxi Huatai Carbon Co Ltd, Shanxi Huaze Aluminum and Electricity Co Ltd, Lanzhou Aluminum Co Ltd, Fushun Aluminum Co Ltd, Jiaozuo Wanfang Aluminum Manufacturing Co Ltd, Fushun Aluminum Corp Ltd, Shandong Huayu Aluminum and Electricity Co Ltd, Gansu Hualu Aluminum Co Ltd, Baotao Aluminum Group Co and Liancheng Aluminum Co Ltd all produce carbon products including carbon anode block, anode paste, semi-graphitic cathode carbon block and semi-graphitic cathode paste, with production capacity of about 12 million tons per year. The products are widely used in electrolytic aluminum industry and other metallurgical industries. They enjoy great reputation not only in China but also abroad with products sold to places as far as Europe, America, and Southeast Asian countries, winning plenty of favorable feedbacks from customers.
