Copper C110
The conductivity king: when watts or amps per gram is the whole point of the part.

Choose it when
When conductivity is everything: nothing affordable carries current or heat better. For contact surfaces specify tin or nickel plating to stop tarnish from degrading performance.
Look elsewhere when
Soft, gummy machining makes fine detail expensive — if the part has intricate features and 93% IACS suffices, tellurium copper C145 machines ~3× faster; for structure, brass or aluminum.
Compatible finishes
As-Machined
The baseline finish: straight off the machine, fastest and cheapest.
Nickel Plating (Electrolytic)
Bright, polishable nickel for decorative protection and contact underlayers.
Tin Plating
The solder-friendly finish: tin for bus bars, terminals and food-contact hardware.
Polishing
Progressive abrasives down to mirror: the finish for optics, molds and show surfaces.
Vibratory Tumbling
Batch deburring by the bowl-full: every edge broken, every burr gone, at volume prices.
Laser Marking
Permanent identification with zero dimensional change: serials, logos and codes burned in, not stuck on.
Typical applications
- Busbars and high-current terminals
- Heat spreaders and vapor-chamber bases
- RF cavities and waveguide internals
- EDM electrodes and welding tips
