Processing & Safety
- Machinability:
- C17300 (Pb-added) achieves exceptional results in CNC turning/milling with an outstanding surface finish Ra < 1.6 μm.
- C17200/C17500 necessitate carbide tools for precision cutting, catering to high-standard requirements.
- Heat Treatment:
- Solution annealing: 760-790°C, followed by rapid cooling to lock in quality.
- Aging: 315-345°C for 2-3 hours to achieve peak hardness and optimal performance.
- Safety Compliance:
- OSHA-compliant handling ensures safe operations with Be dust control maintained at <0.2 μg/m³.
- RoHS/REACH exemptions for Pb in C17300 (EU Directive 2011/65/EU) underline our dedication to regulatory compliance.
