C110 half-hard (H02) is an electrolytic copper of very high purity (~99.9% Cu). This purity translates to excellent electrical and thermal properties, ideal for busbars, connectors, heat sinks, and shielding. Its surface is naturally antimicrobial—an asset in sensitive environments like medical applications.
Key Characteristics
Grade: C110 electrolytic copper with very high purity, high conductivity, and good mechanical properties in half-hard (H02) condition.
Finish: uniform mill finish; can be brushed, polished, or protected with clear lacquer. Copper naturally develops patina over time.
Process: fiber laser cutting or CNC machining for precise tapping (typical tolerance ±0.005").
Cut orientation: the visible face in rendering is treated as the top; use protective film when available.
Assembly: brazing/soldering, soft soldering, hardware and threaded inserts; structural bonding (epoxy) possible depending on use.
Chemical compatibility: avoid ammonia/ammoniacal solutions, chlorinated agents (bleach), and highly corrosive environments; protect from galvanic corrosion in multi-material assemblies.
Thermal: excellent heat conduction; plan for sufficient exchange surface area and clearances for thermal expansion.
Common Applications
Busbars, shunts, connectors, and high-conductivity terminals.
Heat sinks, cold plates, and EMI/RFI shielding.
Electronic components, covers, and conductive mounts.
Plumbing, roofing/flashing, HVAC components, and solar/RV kits.
Decorative plates and lettering, dials, and instrumentation parts.
Design Best Practices
Use small internal radii rather than sharp corners to improve cut quality and limit stress concentrations.
Anticipate bend radius/relief according to thickness and half-hard state; test angles on prototypes when flatness is critical.
Protect visible surfaces during assembly; lightly deburr/deoxidize edges for better brazing and clean finish.
When in contact with aluminum or steel, electrically isolate or apply protection to prevent galvanic corrosion.
