Why CuNi2Si Requires Specialized Machining Expertise

Work-hardening behavior: CuNi2Si hardens rapidly under cutting forces, requiring optimized feeds and speeds
Demanding surface requirements: Electrical and mechanical functions depend on stable micro-finishes
Adhesion challenges: Copper alloys can smear and stick to tools without proper tool coatings and cooling strategies
Dimensional stability: Heat-sensitive alloy composition requires tight thermal control to maintain tolerance
