Processing & Safety
- Machinability:
- C17300 (Pb-added) is superior for CNC turning/milling, achieving a remarkable surface finish Ra < 1.6 μm.
- C17200/C17500 necessitate carbide tools for precision cutting, ensuring impeccable results.
- Heat Treatment:
- Solution annealing conducted at 760-790°C followed by rapid cooling to lock in properties.
- Aging process at 315-345°C for 2-3 hours brings the material to peak hardness.
- Safety Compliance:
- Handling complies with OSHA standards, ensuring Be dust control remains below <0.2 μg/m³.
- RoHS/REACH exemptions apply for Pb in C17300 as per EU Directive 2011/65/EU, maintaining regulatory compliance.
