Copper Metallurgy 201

Learning Outcomes

  • Review influences of alloying elements on mechanical and physical copper properties.
  • Determine transformation temperatures between liquidus and solidus.
  • Identify cooling curves and phase diagrams.
  • Determine phases present in an alloy via application of binary, ternary and complex phase diagrams.
  • Identify and explain various solidification characteristics.
  • Identify and explain various heat treatments of copper castings.

  • Identify key casting defects related to copper metallurgy.

Course Introduction

Knowledge of physical metallurgy of copper alloys is necessary for foundry metallurgists to effectively operate. This knowledge includes melt treatment, effects of alloy additions on physical and mechanical properties, solidification, heat treatment and final properties. The correlations among the processing technology, defects and properties is important to know for metallurgical as well as environmental issues. This course will address these topics to improve the metallurgical skills of the casting personnel.

Benefits to Taking the Course

Participants will leave with the knowledge and skills to reduce the overall cost of metallurgical operations by proper identification and application of cooling curves, construction of phase diagrams and understanding solidification characteristics, as well as effective heat treatment. They will realize profitability gains by improving metallography of cast copper alloys, casting quality identification and proper defect analysis procedures and demonstrate to all other company employees as well as potential customers that quality begins with proper application of copper metallurgical procedures.
