Processing & Safety
- Machinability:
- The C17300 (Pb-added) variant excels in CNC turning and milling, delivering a superb surface finish with Ra < 1.6 μm.
- For precision cutting, C17200 and C17500 demand the use of carbide tools, ensuring precision and efficiency.
- Heat Treatment:
- Conduct solution annealing at 760-790°C followed by rapid cooling for optimal results.
- For peak hardness, execute aging at 315-345°C for 2-3 hours.
- Safety Compliance:
- Adhere to OSHA standards with meticulous handling (Be dust control maintained at <0.2 μg/m³).
- Benefit from RoHS/REACH exemptions for Pb in C17300, as per EU Directive 2011/65/EU, enhancing usage flexibility.
