Available material grades

Copper C110 | CU ETP

Copper (C110) is a pure at 99.90% copper alloy, with universal for electrical applications high thermal conductivity and good corrosion resistance.

Copper C101 | CU OFE

Copper (C101), 99.99% pure, is a copper alloy with excellent conductivity and high corrosion resistance and toughness.

Copper milling

Copper is an incredibly versatile metal, making it an optimal choice for producing CNC machined custom parts. The alloy has several useful properties alongside its versatility—this is why companies working in industries such as electrical, construction, transport and consumer goods use it for many applications. CNC machined copper parts begin as raw pieces of metal that are cut down bit by bit to create a desired shape or object. This process is done most accurately with a CNC (Computerized Numerical Control) machine which can produce almost any three-dimensional object designed via CAD (computer-aided design) software.

Copper parts

We offer a complete copper CNC machining service and can produce complex copper parts in C110 and C101. Copper parts are corrosion resistant and versatile and can be used for applications requiring electrical conductivity and higher quality aesthetics. We operate almost every kind of CNC mill and turning center, and are able to machine whatever you need, from simple, “as-machined” workholdings to complex, organic geometries with tight tolerances. When creating Copper parts with us, you can apply up to 7 different post-processing/surface finishing options including bead blasting, powder coating, smooth machining and polishing.

Copper FAQs

  • 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.
    101 copper offers higher conductivity due to its purity.
    110 copper is generally easier to CNC machine making it more cost effective.
    Copper beryllium (CuBe) combines high strength with non-magnetic and non-sparking qualities. It is excellent for CNC machining, forming and general metalworking.
  • 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.
