Notes
note_altCuZn39Pb3: Maximum Efficiency in Mass Production
In the world of precision engineering, time is the most valuable resource. CuZn39Pb3 (CW614N), manufactured to the highest quality standards by Çorum Bronz, is designed to save you time by maximizing your machining speeds and minimizing tool maintenance. As the most widely used brass alloy for "free-cutting," it is the backbone of the global fastener and small-parts industry.
Why CuZn39Pb3 is Indispensable
The secret to its performance lies in its microscopic structure. The lead (Pb) content is distributed throughout the brass matrix, acting as a chip-breaker and a natural lubricant for cutting tools. This means you can run your CNC machines at their maximum RPM without worrying about tool breakage or tangled "bird-nest" chips.
Lower Tooling Costs: Reduced friction extends the life of your expensive cutting inserts and drills.
Sustainability & Recycling: This alloy is highly recyclable, making it an environmentally responsible choice for large-scale manufacturing.
Excellent Secondary Operations: While optimized for cutting, it also responds well to plating, soldering, and polishing, allowing for a diverse range of final aesthetic finishes.
Çorum Bronz offers CuZn39Pb3 in various profiles—round, hexagonal, square, and custom shapes—all compliant with EN 12164 standards. Our commitment to metallurgical purity ensures that every bar you receive performs consistently, batch after batch.
