Professional Copper CNC Precision Machining Services

AOOM Technology is a trusted CNC machining supplier for high-precision copper components used across electronics, aerospace, medical, and renewable energy sectors. Copper's exceptional electrical conductivity (up to 101% IACS), thermal dissipation properties, and natural corrosion resistance make it the material of choice for critical conductive and thermal applications. Our advanced 5-axis CNC machines and Swiss-type lathes produce complex copper geometries with tolerances up to ±0.005 mm and surface finishes of Ra 0.8 μm or better, meeting the most stringent industry specifications.

Key Technical Specifications

• Tightest tolerances of ±0.005 mm on internal and external features
• Surface finish capability down to Ra 0.8 μm
• Materials: ETP copper (C11000), beryllium copper (C17200), tellurium copper (C14500), brass, bronze
• 5-axis CNC milling and Swiss-type turning for micro-features and complex geometries
• Integrated secondary processes: precision deburring, electroless nickel plating, silver plating, vacuum annealing

Applications

Our copper precision machining supports electronics (micro PCB connectors, BGA heat sinks, RF waveguide components), medical devices (sterilizable surgical instruments, MRI coil housings), automotive EV (busbars, battery terminal connectors, inverter cold plates), renewable energy (solar junction box components, wind turbine slip rings), and defense (radar waveguide assemblies, EMP shielding components).
