Japan’s ferrous PM industry reported a 3.6% gain in production in 2012 to reach 96,979 mt, whilst copper-based PM products showed a more substantial gain to 4,427 mt from 3,567 mt in 2011. The combined total of 101,406 mt amounted to a 4.4% gain over 2011.
The Japan Powder Metallurgy Association (JPMA) reports that production value (in Japanese Yen) for structural PM parts also rose slightly in 2012 but was still substantially below the peak reached in 2007 (Fig. 1).
Around 92% of all structural PM parts produced by Japan’s 63 PM producers find applications in the automotive sector with the average Japanese car containing 9.2 kg of PM parts (2011).
PM self-lubricating bearing production in Japan was relatively flat in 2012 reports the JPMA. The breakdown of PM parts and PM bearings applications in vehicles in 2011 is shown in Fig. 2
