Our Copper Materials

We offer copper and brass. The main difference between copper and brass is that copper is a base metal, while brass is an alloy. Brass consists of copper and zinc. Cu materials have excellent electrical conductivity, good tensile strength, good corrosion resistance, and low friction coefficient, making both CNC machined copper and brass parts are applied in various applications. Various surface finishing options are available for copper/ brass CNC parts.

Advantages

Advantages

  • Highly efficient machining. As cooper alloys have great machinability, sometimes referred to as 100% machinability, creating copper/ brass parts by CNC machining at a high speed is feasible.
  • High dimensional accuracy and stability. Copper and it alloys are known for dimensional stability and can be machining with tight tolerance.
  • Great tool compatibility. Copper alloys workpieces are highly compatible with various CNC machining tools. Tool durability and frictionless machining guarantee efficiency and productivity.
  • Reduce costs. Making copper and its alloy parts with CNC machining for one prototype to low-to-medium production.

How to CNC machining Copper?

 

 
 

Step 1. Convert the CAD file into a language that CNC machines can work with, that's G-code..

 
 

Step 2. The operator will place the copper/ brass workpiece that is cut to a specific size on the machine bed. Then it is time to mount the copper/brass workpiece on the machined bed or by a vice.

 
 

Step 3. As the computer controls the CNC cutting tools to move to the pre-set coordinates, so precise positioning and alignment of the copper/ brass workpiece is significant to manufacture high-accuracy parts. Special metrology tools, probes, for instance, are ideal solutions for this step.

 
 

Step 4. Then, the copper/ brass workpiece is ready for machining. The machine uses professional cutting tools and rotating the at high speeds to remove material from the workpiece. However, at the very first steps, the machine removes at a relatively low speed and accuracy to gain an approximate geometry.

 
 

Step 5. Sometimes, the model is not being to achieve full features by single setup from the cutting tools, then to flip the copper/ brass workpiece is necessary.

Frequently Asked Questions

1. How much does it cost to CNC machining Copper parts?

Prices are based on the structure of the part, order volume, machining processes, etc. You can use our instant quoting engine to get price, or you can email hello@wenext.com for more information.

2. What is Copper CNC machining?

Copper CNC machining is the process of cutting and removing excess materials on the copper or its alloys workpiece until the final object with desired geometries.

3. What kind of finishes are possible with Copper CNC machining?

We provide various surface finishing options, including as machined, polishing, sandblasting, plating, coloring, lase etching, heat treatment, screen printing, anodizing, etc. Please check details Here.

4. Can copper rust?

Copper will never rust because it contains too little iron.

5. Does copper react with water?

Copper and Gold do not react with water, because they lie below hydrogen in the reactivity series.

6. How does copper turn green?

Copper will start to react with the oxygen in the air to form copper oxide. The copper oxide will continue reacting to oxygen over time. As the copper oxide continues to react with carbon dioxide and water in the air it coats the surface with that iconic blue-green patina colour.

7. How to keep copper from turning green?

Coat the copper item in a protective coating to prevent the product turning green. Please check our surface finishing options Here or contact our Customer Success Manager for more information.
