MaterialCombination

MaterialCombination describes situations where multiple materials are paired in the design, such as coatings, bonded assemblies, or inserts. The model holds a reference id and the list of constituent Material objects that make up the combination. By structuring these combinations you can evaluate compatibility, plan multi-material manufacturing steps, or flag drawings that require special supply chain considerations. It also helps quality teams ensure that materials specified together—such as a base metal and its coating—are captured as a unit rather than as unrelated entries. The structured data enables sustainability tracking or hazardous material declarations too.
