Processing & Safety
- Machinability:
- C17300 (Pb-added) achieves excellence in CNC turning/milling with a refined surface finish of Ra < 1.6 μm.
- C17200/C17500 demand the use of carbide tools for achieving precision in cutting.
- Heat Treatment:
- Solution annealing involves a temperature range of 760-790°C, followed by rapid cooling.
- Aging process maintained at 315-345°C for 2-3 hours to attain peak hardness.
- Safety Compliance:
- OSHA-compliant handling measures are in place, ensuring Be dust control remains below <0.2 μg/m³.
- Exemptions under RoHS/REACH for Pb in C17300, as per EU Directive 2011/65/EU.
