Processing & Safety
- Machinability:
- C17300 (Pb-added) excels in CNC turning/milling (surface finish Ra < 1.6 μm).
- C17200/C17500 require carbide tools for precision cutting.
- Heat Treatment:
- Solution annealing: 760-790°C, rapid cooling.
- Aging: 315-345°C for 2-3 hours (peak hardness).
- Safety Compliance:
- OSHA-compliant handling (Be dust control: <0.2 μg/m³).
- RoHS/REACH exemptions for Pb in C17300 (EU Directive 2011/65/EU).
