How Modo Rapid Ensures Your Copper Parts Remain Deformation-Free
Copper is a versatile material, but machining it requires special attention. At Modo Rapid, we prioritize your needs and ensure your copper alloy parts maintain their integrity throughout the CNC machining process.
Heat Buildup
Copper alloys are softer than many materials, leading to potential deformation under high heat. We manage this by optimizing the CNC machine RPM and using a larger chipload. Our high-pressure coolant systems ensure the cutting tools remain cool and effective, delivering high-quality copper parts for you.
Galling
Copper can become sticky and adhere to the cutting tool. To prevent this, we use high-pressure coolant and ensure swift chip removal. This mitigates heat buildup and extends tool life, delivering precise parts that meet your specifications.
Workholding
Copper’s malleability requires a firm grip during CNC machining. We maintain a tight hold and ensure constant tool motion without interruptions. This prevents deformation and guarantees that your parts are machined to perfection.
At Modo Rapid, we understand the challenges of machining copper and employ expert techniques to ensure your parts remain flawless and deformation-free.

Volume Discounts and Minimum Order Quantity
At Modo Rapid, we offer volume discounts to accommodate larger production runs. The discounts increase with the order size, making it more cost-effective for bulk purchases. We understand the diverse needs of our clients, so we have set a flexible minimum order quantity to cater to both small and large projects.
Example: Cost Calculation
Let’s assume we have a copper alloy part with the following specifications:
- Dimensions: 100mm x 50mm x 10mm
- Complexity: Medium complexity geometry
- Surface Finish: Anodized
- Quantity: 50 pieces
Material Cost
- Price of copper alloy: $10/kg
- Weight per part: 0.4 kg
- Total material cost: 50 pieces x 0.4 kg x $10/kg = $200
Machining Cost
- Machining time for medium complexity parts: 2 hours/part
- Machining rate: $100/hour
- Total machining cost: 50 pieces x 2 hours/piece x $100/hour = $10,000
Surface Finish Cost
- Anodizing cost: $20/piece
- Total surface finish cost: 50 pieces x $20/piece = $1,000
Tool and Equipment Wear
- Copper alloy causes significant tool wear, requiring frequent replacement
- Estimated tool and equipment wear cost: $500
Other Costs
- Quality control and inspection fees: $500
- Packaging and shipping fees: $200
Total cost = Material cost + Machining cost + Surface finish cost + Tool and equipment wear + Other costs
Total cost = $200 + $10,000 + $1,000 + $500 + $700 = $12,400
Cost per part = Total cost / Quantity
Cost per part = $12,400 / 50 pieces = $248/piece
This example provides a rough estimate of the cost. Actual costs will vary based on specific designs, process requirements, and quantities.

FAQ
Copper materials are a significant category of commercial metals, with various grades available for CNC machining. These grades have different properties and compositions, making them suitable for specific machining projects.
Choosing the right copper material involves considering the specific properties required for your project. Factors such as electrical conductivity, machinability, and strength are critical in determining the best copper grade.
Pure copper is typically soft and malleable, with 0.7% total impurities in commercial grades. It can be alloyed in small volumes to modify its primary properties. Pure copper is ideal for electrical components like wiring and motors and is also used in manufacturing heat exchangers. Its UNS designation numbers range from C10100 to C13000.
Electrolytic copper comes from cathode copper with 99.95% purity, processed through electrolysis. This process involves putting copper compounds into a solution and applying electricity to purify the material. C11000 is a common electrolytic copper grade, known for its high electrical conductivity and ductility, making it perfect for electrical applications such as busbars, windings, wires, and cables.
Oxygen-free copper has the highest purity with little to no oxygen content, making it ideal for electrical components due to its high conductivity. C10100 (Oxygen-Free Electronic) and C10200 (Oxygen-Free) are typical examples. C10100 contains about 0.0005% oxygen and is more expensive, while C10200 contains 0.001% oxygen and offers high electrical conductivity equivalent to electrolytic copper materials.
Oxygen-free copper is made from high-quality cathode copper through induction melting. This process involves melting the cathode under non-oxidizing conditions created by a graphite bath covering, reducing the hydrogen content in the working environment.
Free-machining copper contains various alloying elements like zinc, nickel, phosphorus, and tin, enhancing its machinability. Brass (zinc and copper) and bronze (tin, copper, and phosphorus) are significant constituents, offering excellent workability, corrosion resistance, impact strength, and hardness.
Free-machining copper is well-suited for a wide range of machining applications, including gears, coins, automotive hydraulics, torches, and machined electrical components.
This FAQ aims to provide a clear understanding of the various copper grades used in CNC machining and their specific properties and applications. For more detailed information or to choose the best copper grade for your project, please contact Modo Rapid.
Machining copper is challenging due to its softness and tendency to adhere to cutting tools (galling). Its high thermal conductivity can also lead to heat buildup, causing tool wear and deformation.
Tellurium copper (C14500) is considered the best machinable copper due to its improved machinability while retaining good electrical conductivity.
Copper is generally harder to machine than aluminum due to its tendency to gall and lower thermal conductivity, which can lead to more tool wear and heat management issues.
Grades like C110 (Electrolytic Tough Pitch Copper) and C145 (Tellurium Copper) are commonly used for machining due to their favorable properties.
Milling speeds for copper typically range from 150 to 300 meters per minute, depending on the specific alloy and tooling used.
No, cast iron is generally stronger and harder than copper, making it more suitable for applications requiring high strength and wear resistance.
- Pure Copper (e.g., C10100, C11000)
- Oxygen-Free Copper (e.g., C10100, C10200)
- Free-Machining Copper (e.g., C14500)
Type M copper, with its thinner wall, is suitable for low-pressure residential applications but not recommended for heavy-duty or high-pressure uses.
Free-machining copper contains alloying elements like tellurium or sulfur, which enhance its machinability. C14500 is a common example.
For machining copper, 2 to 3 flutes are typically recommended to allow for efficient chip removal and prevent clogging.
A 2 flute end mill has better chip clearance and is ideal for softer materials, while a 4 flute end mill provides a better finish and is suitable for harder materials.
Copper is durable and has a long lifespan, making it ideal for high-temperature and high-pressure applications. PEX is easier to install, flexible, and cost-effective for residential plumbing.
Type K copper has the thickest walls among copper pipes, making it suitable for high-pressure applications and underground installations.
