Claim 7:
8. The bimodal powder mixture of claim 1, wherein the bimodal powder has a first corrected pressed density ≥3.2 g/cm3, wherein the first corrected pressed density is calculated with the formula PD/100×(100+ID10); wherein PD is the pressed density under a pressure of 200 MPa and ID10 is the increase of the D10 value in the particle size distribution of the bimodal powder calculated as follows:, ID
