Processing & Safety
- Machinability:
- C17300 (Pb-added) stands out in CNC turning/milling with an impressive surface finish Ra < 1.6 μm, while C17200/C17500 demand the precision of carbide tools for cutting-edge results.
- C17200/C17500 require carbide tools for precision cutting.
- Heat Treatment:
- Solution annealing is achieved at 760-790°C followed by rapid cooling to ensure structural integrity.
- Aging: Conducted at 315-345°C for 2-3 hours to achieve peak hardness and optimal performance.
- Safety Compliance:
- In compliance with OSHA standards, our handling processes ensure Be dust control remains below 0.2 μg/m³.
- RoHS/REACH exemptions for Pb in C17300 (EU Directive 2011/65/EU).
