    GRCop-42 and the Copper Powder Feedstock Problem in Laser Powder Bed Fusion

    Copper reflects most near-infrared laser light and conducts absorbed heat away faster than almost any other engineering metal. GRCop-42's move into commercial powder catalogs shows how feedstock morphology, oxide content, and particle size distribution are being engineered around that problem rather than worked around it.

    Hausner Ratio and Carr Index: What the Numbers Tell You and Where They Break Down

    Both the Hausner Ratio and Carr Index reduce bulk and tapped density to a single number. The mechanism behind that number, whether aeration, particle shape, or surface cohesion, determines whether it supports a process decision or actively misleads one.
