CNC Machining in Copper
Designers and engineers frequently choose cooper and copper alloys for CNC machining and CNC milling parts. Makes sense. This all-purpose metal has been proven to offer:
- * Unmatched Conductivity
- * Inherent Antibacterial Properties
- * Hardness
- * Thermal Management
- * Corrosion resistance
- * Workability
- * Low weight
- * Low cost
- * Overall versatility
Description
- Applications
- Electrical wiring / Power transmission / Plumbing / Heat exchangers / Architectural trim
- Strengths
- Best electrical conductivity (besides silver) / Excellent thermal transfer / High corrosion resistance / Antibacterial / Easy to cold-form
- Weaknesses
- Heavy vs. aluminum / Soft → scratches easily / Expensive material / Develops patina (tarnishes)
- Process compatibility
- CNC Machining/Milling / Stamping / Tube extrusion / Pipe welding (TIG/brazing)
- Surface Treatment
- Electroplating (Ni/Cr/Sn) / Chemical patination / Clear coating (anti-tarnish)
Characteristics
- Price
- Aluminum has a wide range of applications from prototyping to automotive to aerospace.

Coppers for Machining
CNC Machined COPPER
Copper excels in cnc machining for its unmatched electrical conductivity and heat transfer properties making it essential for high performance electronic components and thermal management systems like bus bars and heatsinks its natural corrosion resistance suits marine and medical applications though machining requires sharp carbide tools and high pressure coolant above 1000 psi to manage gummy chips and prevent workpiece deformation feed rates must balance speed and heat control typically 150 to 400 sfm with precise chip breakers to avoid edge buildup common alloys include oxygen free copper c101 for pure conductivity free cutting brass c360 for intricate parts and beryllium copper c172 for strength post processing like electropolishing enhances surface finish to ra 01 micrometers while nickel plating or chromate passivation boosts durability in harsh environments material selection depends on functional needs whether maximizing electrical flow in power systems or achieving complex geometries in decorative hardware
