Copper Cnc Machining Service
Our Copper Cnc Machining Service Material Choice
We machine four primary copper grades—C101, C102, C110.—each optimized for specific applications. From maximum conductivity to superior machinability, find the perfect copper grade for your requirements.
Extremely pure and completely oxygen-free, Copper 101 stands out as one of the best options for applications requiring maximum electrical and thermal conductivity. Its exceptional purity makes it highly resistant to corrosion and remarkably easy to weld or solder.
Key Properties:
- Purity: 99.99%
- Electrical Conductivity: ≥101% IACS
- Thermal Conductivity: ~390 W/(m·K)
- Density: 8.94 g/cm³
- Tensile Strength: 220-270 MPa
- Elongation: 40-55%
Known as ETP copper, Copper 110 contains trace oxygen which actually enhances its strength while maintaining excellent conductivity. This makes it the most widely used copper grade, offering the perfect combination of performance, formability, and affordability.
Key Properties:
- Purity: 99.90%
- Electrical Conductivity: ~100% IACS
- Thermal Conductivity: ~385 W/(m·K)
- Density: 8.94 g/cm³
- Tensile Strength: 200-250 MPa
- Elongation: 30-40%
Similar to Copper 101 but with slightly more impurities, Copper 102 still delivers outstanding conductivity while being resistant to corrosion. It strikes an excellent balance between performance and cost-effectiveness for many electrical applications.
Key Properties of C230 Red Brass:
- Purity: 99.95%
- Electrical Conductivity: ≥100% IACS
- Thermal Conductivity: ~390 W/(m·K)
- Density: 8.94 g/cm³
- Tensile Strength: 210-260 MPa
- Elongation: 35-50%
Our Copper Cnc Machining Surface Finishing Choice
We machine four primary copper grades—C101, C102, C110.—each optimized for specific applications. From maximum conductivity to superior machinability, find the perfect copper grade for your requirements.
As Machined Brass Finish
This is the default finish directly from the CNC machine. Tool paths and marks are visible. It’s ideal for functional or internal components where appearance isn’t a priority. Cost-effective and fast, this finish is often used for prototypes and parts not requiring surface refinement.
Sand Blasting for Brass Parts
Sand or other abrasives are sprayed at high speed to create a uniform matte or satin texture. This process effectively removes surface imperfections and provides a consistent base for further coatings like painting or anodizing.
Brass Tumbling Finish
Also known as barrel finishing, this method involves placing parts in a drum with abrasive media. As the drum rotates, it smooths and deburrs the surface. Tumbling is commonly used for small brass parts to achieve a semi-polished or even satin-like finish.
Electropolishing for Brass
This electrochemical process removes a thin layer of the metal surface, reducing roughness and enhancing brightness. It also improves corrosion resistance and is particularly beneficial for complex or small components that are difficult to polish mechanically.
Alodine Finish for Brass Parts
We accept STEP, IGES, SolidWorks, Inventor, Fusion 360, CATIA, and other CAD formats. 2D drawings in PDF or DWG also accepted.
Electroless Nickel Plating on Brass
A chemical plating technique that coats brass with a uniform layer of nickel, enhancing hardness, corrosion resistance, and wear properties. Unlike traditional electroplating, it doesn’t require electricity, making it ideal for parts with complex geometries.
Painting for Brass Components
A versatile finishing method that adds color, UV protection, and surface sealing. Various paint types can be applied depending on the part’s environment and purpose, ranging from decorative to functional coatings.
Powder Coating for Brass Parts
A durable, protective finish where powder is electrostatically applied and then cured under heat. It offers excellent abrasion and weather resistance and is available in a wide variety of colors, sheens, and textures.
Electrophoresis Coating
This method uses an electric field to deposit a uniform, corrosion-resistant film over brass parts. It is ideal for coating intricate shapes and internal surfaces and can be used in combination with powder coating or paint for enhanced durability.
Brushed Brass Finish
A linear pattern is created on the surface using brushes or abrasive belts. The resulting texture gives a clean, satin appearance. It’s commonly found in high-end electronics, appliances, and decorative parts due to its modern and premium look.
