Bronze vs Copper: What is the difference? How to Choose? - DEK

Bronze is hard and study, not easily flexed compared to highly flexible copper. Also, alloys of copper are pretty much ductile to machine. As the case may be, if machinability is a goal in selecting either bronze and copper for a project, it is of no doubt that copper is a perfect choice. Bronze vs Copper: Formability
