Preface
In the realm of CNC machining parts manufacturing, material selection is paramount. Red copper, also known as pure copper or electrolytic tough pitch (ETP) copper, stands out due to its exceptional properties. Understanding the density of red copper is essential for engineers and machinists in custom CNC machining, as it influences material behavior, machining parameters, and the final product's performance.
Definition of Density
Density is a fundamental physical property defined as the mass per unit volume of a material. It quantifies how much matter is packed into a given space and is mathematically expressed as:
In CNC machining, knowing the density of materials like red copper helps in calculating weight, designing components, and ensuring structural integrity.

Understanding these units allows for accurate calculations in CNC machining services and ensures compatibility with various engineering standards.
Red copper has a density of approximately 8.96 g/cm³ (or 8,960 kg/m³). This high density is one of the reasons red copper is prized in CNC machining parts manufacturing. The density affects not only the weight but also the material's mechanical properties, such as strength and durability.
In custom CNC machining, accurate knowledge of red copper's density is crucial for:
Red copper is renowned for its remarkable properties that make it suitable for a wide range of applications. In a CNC machining factory, these characteristics translate into benefits like ease of machining, superior product performance, and customer satisfaction.
Excellent Electrical Conductivity
Red copper boasts the highest electrical conductivity among commercial metals, at about 100% IACS (International Annealed Copper Standard). This makes it the material of choice for electrical components, wiring, and conductors in CNC machining parts.
Good Thermal Conductivity
With a thermal conductivity of approximately 401 W/(m·K), red copper efficiently dissipates heat. This property is essential in applications like heat exchangers and thermal management systems, where custom CNC machining can create intricate designs for optimal performance.
Corrosion Resistance
Red copper naturally forms a protective oxide layer when exposed to the atmosphere, providing resistance to corrosion. This enhances the longevity of CNC machined parts, especially in harsh environments.
Good Ductility and Plasticity
Red copper's ductility allows it to be drawn into thin wires without breaking, and its plasticity enables it to be formed into complex shapes. In CNC machining services, this means it can be machined into intricate components without compromising structural integrity.
Antibacterial Properties
Copper possesses inherent antibacterial properties, making it ideal for medical equipment, touch surfaces, and antimicrobial applications. CNC machining factories can produce red copper parts that contribute to healthier environments.
Beautiful Color
The distinctive reddish hue of red copper adds aesthetic appeal, making it popular in architectural elements and decorative items. Custom CNC machining can craft visually appealing components that also serve functional purposes.
High Temperature Resistance
Red copper maintains its mechanical properties at elevated temperatures, with a melting point of 1,085°C (1,985°F). This makes it suitable for applications requiring thermal stability, such as in industrial furnaces or high-temperature electrical systems.
Recyclability
Copper is 100% recyclable without loss of quality. This sustainability aspect is increasingly important in modern manufacturing and aligns with eco-friendly practices in CNC machining services.
Low Magnetism
Red copper is diamagnetic, meaning it exhibits very weak magnetic properties. This is advantageous in applications where magnetic interference must be minimized, such as in sensitive electronic equipment.
Excellent Processability
Red copper's softness and malleability make it easy to machine, cut, and form. In a CNC machining factory, this translates to reduced tool wear and faster production times, enhancing efficiency.
Physical Properties
Chemical Properties
Understanding these properties helps CNC machining services optimize processes, select appropriate tooling, and ensure the final product meets the desired specifications.
While red copper is known for its consistent density, certain factors can cause slight variations. Recognizing these factors is crucial in custom CNC machining to maintain precision and quality.
3 Factors That Cause Density Changes
Purity
Impurities in copper can alter its density. Higher purity levels ensure consistent density and predictable material behavior. In CNC machining parts, using high-purity red copper guarantees uniformity and reliability.
Alloying Elements
Adding other metals to copper forms alloys, which can change the density significantly. For instance, adding zinc to create brass lowers the density, while adding nickel to create cupronickel slightly increases it. CNC machining services must account for these changes when selecting materials.
Temperature
Thermal expansion causes materials to expand at higher temperatures, slightly decreasing density. While this effect is minimal in solids like copper, it's essential in high-precision CNC machining where thermal effects can impact dimensional accuracy.
Copper alloys are created to enhance certain properties like strength, corrosion resistance, or machinability. Understanding the density of these alloys is important in CNC machining factory operations.
Brass (Copper-Zinc Alloy)
Bronze (Copper-Tin Alloy)
Cupronickel (Copper-Nickel Alloy)
In custom CNC machining, selecting the appropriate copper alloy involves considering both the material properties and the density to meet the specific requirements of the project.
Comparing red copper's density with other metals helps in material selection for CNC machining parts, especially when weight is a critical factor.
