C17200 Machining Capabilities

القدرة	الوصف الفني	ميزة Jucheng
Hard Metal Strategy	C17200 can reach 45 HRC. We machine parts in the annealed state (Solution Heat Treated) for efficiency and perform finish-machining after aging.	Our rigid CNC setups handle the high cutting forces of hardened beryllium copper, maintaining +/- 0.005mm tolerances on aerospace bushings.
Precision Swiss Turning	Manufacturing miniature spring pins and electrical sockets with intricate internal features.	We achieve mirror finishes and burr-free edges on complex electronic connectors, ensuring 100% reliable mating cycles.
Age Hardening Management	Managing the critical precipitation hardening process (Condition AT to HT) to maximize mechanical properties.	Jucheng provides a complete turnkey solution, ensuring the parts achieve peak hardness and fatigue strength through controlled heat treatment.
تفريز خماسي المحاور معقد	Milling high-strength structural components and non-sparking tools from solid C17200 blocks.	Our 5-axis capability allows us to machine organic shapes and deep cavities in this abrasive material with minimal tool deflection.

Fabrication Guidelines for C17200 Beryllium Copper

Safety First (Dust Control):
Beryllium dust is a known health hazard. نصيحة: We utilize specialized wet-machining environments and high-efficiency filtration systems to ensure all particulates are safely contained during the CNC process.

اختيار الأدوات:
C17200 is highly abrasive. نصيحة: We use sub-micrograin carbide tools with specialized coatings (like TiAlN or Diamond-like Carbon) to withstand the wear and maintain edge sharpness over long runs.

Work Hardening Awareness:
This alloy work-hardens rapidly if the tool rubs. نصيحة: We maintain a constant, positive feed rate and never allow the tool to dwell, ensuring the material is sheared cleanly to prevent surface stress.

Magnetic & Sparking Properties:
C17200 is non-magnetic and non-sparking. نصيحة: This makes it the premier choice for tools used in explosive environments or for components within sensitive magnetic resonance equipment.
