Processing & Safety
- Machinability:
- The C17300 alloy, enhanced with Pb, demonstrates superior performance in CNC turning and milling, achieving an exceptional surface finish with an Ra value of less than 1.6 μm.
- Our C17200 and C17500 alloys demand the precision of carbide tools for cutting, ensuring accuracy and quality.
- Heat Treatment:
- Optimize your process with solution annealing at 760-790°C followed by rapid cooling.
- Achieve peak hardness through aging at 315-345°C for a duration of 2-3 hours.
- Safety Compliance:
- Our handling procedures comply with OSHA standards, ensuring that Be dust levels remain below 0.2 μg/m³.
- Benefit from RoHS/REACH exemptions for Pb in C17300, aligned with EU Directive 2011/65/EU.
