Influence of aluminum addition on the laser powder bed fusion of copper-aluminum mixtures

Influence of aluminum addition on the laser powder bed fusion of copper-aluminum mixtures

The high optical reflectivity of copper (Cu) in the near infrared (NIR) domain and its elevated heat dissipation make Cu a challenging metal for laser powder bed fusion (LPBF), even with high energy densities (EDs). In this study, we demonstrated that adding aluminum (Al) powder by as little as 0.75...
