Viscosity of L68 Brass Melts

The viscosity thermophysical property data is included with the TCS Cu-based Alloys Database (TCCU) as of version 4 (TCCU4).

The viscosity is a critical material property needed when performing finite element simulations of casts or welds. Thermophysical data found in handbooks and finite element (FE) codes typically does not capture chemistry variation or data for novel/experimental materials. Below is the calculated viscosity for a specific chemistry of L68 brass compared with some measured values.
