Important Things Should Know About Copper CNC Machining

Copper is a widely used material for specific industrial and commercial parts creation. It’s not surprising considering the properties of copper, such as excellent mechanical strength, corrosion resistance, and thermal and electrical conductivity. With increasingly complex part designs and copper geometries, conventional fabrication methods cannot fulfill all the requirements. CNC machining makes a significant difference here. Copper CNC machining is widely employed across industries for fabricating copper parts for the level of precision if offered. Hence, copper CNC machining is in demand and preferred by most OEMs and machining service providers. This post discusses some popular copper grades used for CNC machining and answers everything regarding copper CNC machining. So, stay tuned

Commonly Used Copper Grades for CNC Machining

Here are some common grades of copper used for CNC machining.

  • Brasses:This alloy comprises zinc and copper, thus widely used in various applications. Brasses are well-known for easy workability, excellent hardness, ductility, strength, conductivity, and more. This copper alloy is mainly machined to produce intricate and low-friction parts.
  • Bronze:This is an alloy of tin and copper. Phosphorus is added for deoxidization. This copper alloy is used to produce gears and bearings.
  • Copper 101:This alloy is the purest grade of copper, featuring 99.9% Cu. It can be used as the base for both brass and bronze alloys.
  • Copper 110:This grade features 99.9% Cu and is easier to machine than copper 101. Copper 110 is the best choice for many electrical applications.
  • Nickel-Silvers:This is an alloy of nickel, zinc, and copper. They are much similar to the brasses. However, they are more corrosion resistant than brasses.
  • Copper-Nickel Alloy:This copper grade is best for marine environments. They are known for their features, including excellent ductility and corrosion resistance.

Benefits Offered by CNC Machined Copper Parts

Most OEMs prefer CNC machining over conventional manufacturing processes owing to its precision, repeatability, and high productivity. This advanced manufacturing technique allows manufacturers to make the best use of material properties, increase speed, precision, and efficiency, and reduce wastage. Here are some important benefits of copper combined with CNC machining that have largely contributed to the demand for CNC machined parts. So, let’s have a look at them.

  • Copper is easy to fabricate using a CNC machine. This helps achieve complex shapes and designs with reduced effort, time and increased accuracy.
  • As copper is soft, it is heat-treated to get desired hardness for making durable and quality parts.
  • The demand for CNC machined copper parts has increased over the years. Wondered why? It is owing to its capacity to resist the applied load. This property of copper makes it an ideal choice for building complex parts in industries like automotive, aerospace, and so on.
  • Copper is an excellent conductor of heat and electricity. Also, it is non-magnetic and non-sparking, making it the preferred choice for electrical components and telecommunication parts.
  • Copper and its alloys offer good resistance to corrosion, thus making them a good choice for oil and gas equipment parts, marine equipment, undersea telecom parts, and so on.
  • Aside from this, CNC machined copper parts have good formability in both cold and hot processes. Also, these parts are compatible with many cost-effective surface finishes.
