Copper-based Alloys - Thermo-Calc Software

TCCU7 for Thermodynamic and Properties Data

TCCU7 is a thermodynamic and properties database for copper-based alloys. It includes nearly all stable phases in the assessed systems that may form in as-cast and aged Cu-based alloys.

TCCU7 was developed to be used with our entire suite of products: Thermo-Calc, the Add-on Modules, and all available SDKs.

MOBCU6 for Kinetic Data

MOBCU6 is a corresponding mobility database that provides kinetic data for those working with the add-on kinetic modules – the Diffusion Module (DICTRA) and the Precipitation Module (TC-PRISMA) – as well as a few specific calculation types, such as Scheil with back diffusion. If you do not purchase a license for an add-on kinetic module, you most likely do not need a mobility database. One of our technical sales representatives can help you determine whether your work requires a mobility database.

MOBCU6 is compatible and recommended to be used in combination with TCCU7.
