              Sintering carbon loss usually at the level of 0.15~0.25wt% for these alloy powder materials.

              • Sintered surface is very smooth by using HJ’s MIM powder material design.
              • With very fine and uniform crystal structure, sintered grain size can reach or higher than grade 7.
