The global demand for metal powders is expected to reach $ 3.52 billion in 2012

Posted by tracy ma on Tuesday, November 15, 2011, In : metal powder 

The global demand for metal powders is expected to remain at 35 billion U.S. dollars in 2012, although the demand will grow 1.8% to reach 1.2 billion pounds. The reason is mainly due to metal prices will be lower than the high level of 2007; and 2002-2007 base metal powder, no significant change in demand.

Will increase the number of new uses for steel, stainless steel, aluminum and tungsten metal powder and other applications, such as powdered metal parts of motor vehicles in a wide range of ...
