TOBO Industrial (Shanghai) Co., Ltd., a leading manufacturer and global supplier of precision-engineered metal products, has announced the expansion of its advanced alloy portfolio with the introduction of Copper-Nickel Alloy Straight Oil Pipes specifically engineered for machine tool and lathe applications. These high-performance tubes are complemented by integrated bending, cutting, and welding services, delivering a complete, ready-to-install solution for critical lubrication and hydraulic systems in precision machining equipment .
The Material Advantage: Copper-Nickel Alloys for Demanding Machine Tool Applications
Copper-nickel alloys, particularly the 90/10 (C70600) and 70/30 (C71500) variants, are widely recognized for their exceptional performance in demanding industrial environments. These alloys offer a unique combination of properties that make them ideal for machine tool oil pipe and water tube applications :
Superior Corrosion Resistance: Copper-nickel alloys exhibit outstanding resistance to corrosion from lubricating oils, coolants, water, and mild chemical environments. The protective surface film that forms naturally on these alloys ensures long-term reliability even in continuous operation .
Excellent Thermal Conductivity: With thermal conductivity of approximately 40 W/m·K for 90/10 alloy, these pipes efficiently dissipate heat generated during machining operations, contributing to stable machine tool performance .
High Mechanical Strength: Copper-nickel alloys maintain structural integrity under vibration, pressure cycling, and thermal expansion—conditions commonly encountered in high-speed machining centers and lathes.
Natural Biofouling Resistance: The alloy's surface chemistry inhibits the growth of bacteria and biofilm in water-based cooling systems, maintaining flow efficiency and reducing maintenance requirements.
