101 and 110 copper alloys offer excellent thermal and electrical conductivity, which make them natural choices for bus bars, wire connectors, and other electrical applications. While 101 (also known as super-conductive copper) offers higher conductivity due to its purity (99.99% copper), 110 is generally easier to machine and thus more cost-effective.

Cost Saving Tip
To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
Is copper hard to machine?
Pure copper CNC machining is very difficult to and requires specialized knowledge. Alloying the copper with elements such as tin, silicon, zinc, aluminum, and nickel can drastically improve machinability because it changes the material composition.
What is the best type of copper for CNC machining?
Copper alloys have great electrical and thermal conductivity, which make them natural choices for many electrical applications, such as bus bars and wire connectors.
What are the benefits of machining copper?
Copper’s unique benefits and properties make it a valuable material for a wide variety of applications and is easy to machine.
Copper has good corrosion resistance and is especially malleable and ductile. It is a good heat and electricity conductor and can be hard and soft soldered easily.
With copper CNC machining, precise copper parts can be produced quickly and with a high level of repeatability, ensuring each part meets strict requirements and specifications.
Copper is suitable for a wide array of applications such as pipes, electric cabling, circuit boards, electronics, wiring, radiators and cooling systems.
