Powder Metallurgy (Metal compression molding) is the most cost effective of a number of possible options for making the part. * Very high and uniform purity can be easily achieved * the simple fabrication process retains purity * Grain size is easily controlled * No deformation is needed to produce directional elongation of grains * Void density can be controlled * Objects can be created in any shape * Shapes can be produced that not be made by any other process PM material refer to MPIF standard 35 No. class common grade 1 Iron and Carbon Steel F-0000 F-0005 F-0008 2 Iron-Copper and Copper Steel FC-0205 FC-0208 FC-0508 3 Iron-Nickel and Nickel Steel FN-0205 FN-0208 FN-0405 4 Prealloyed Steel FL-4205 FL-4605 FL-5208 5 Hybrid Low-Alloy Steel FLN2C-4005 FLN2-4405 FLNC-4405 6 Sinter-Hardened Steel FLN2-4408 FLNC-4408 FLC2-4808 7 Diffusion-Alloyed Steel FD-0205 FD-0405 FLDN2-4908 8 Copper-Infiltrated Iron and Steel FX-1005 FX-2005 FX-2008 9 Copper and Copper Alloys CZP-1002 CZ-3000 CT-1000 Surface Heat Treatment(Surface carburizing, nitriding, carburizing and high frequency quenching) -Black Oxide Finish -Immersion Oil -Electroplating
