Product Description

Precision Copper Parts

Precision copper parts refer to mechanical parts made of pure copper or copper alloy materials through precision processing technology, which have high electrical conductivity, thermal conductivity, corrosion resistance and good mechanical properties. Its core value lies in meeting the stringent requirements of functionality, durability and reliability in the industrial field, such as as a conductor in electrical systems and as a wear-resistant part in mechanical structures.

Material Classification and Characteristics

The material selection of precision copper parts directly affects its performance and application scenarios, and is mainly divided into four categories:

Red Copper (Pure Copper): The best conductivity (second only to silver), used for precision electronic components, wires and cables and radiators.

Brass (Copper-Zinc Alloy): High strength and good wear resistance, commonly used in mechanical parts such as valves, gears, and connectors.

Bronze (Tin Bronze, Aluminum Bronze, etc.): Wear-resistant and impact-resistant, suitable for high-load environments such as bearings and pump bodies.

Nickel Silver (Copper-Nickel Alloy): Corrosion resistance and excellent ductility, widely used in medical devices, marine equipment and precision instruments.

Characteristics and Process Difficulties of Precision Copper Parts Processing

Precision copper parts processing needs to take into account both precision and material properties. The key features include:

High Precision Requirements: The tolerance range is often controlled within ±0.01mm, relying on CNC machine tools (CNC) and precision molds.

Complex Surface Treatment: polishing, electroplating or anodizing are required to improve corrosion resistance and aesthetics.

Strict Process Control: Copper materials are easy to deform, and cutting parameters (such as feed speed, tool angle) and cooling and lubrication systems need to be optimized to avoid work hardening.

Precautions During Processing

To ensure the quality of the finished product, the following links need to be focused on:

● Material Pretreatment: remove the surface oxide layer, detect the chemical composition and mechanical properties, and avoid impurities affecting processing.

● Equipment Selection: Use high-rigidity machine tools and special tools (such as carbide milling cutters) to reduce surface defects caused by vibration.

● Process Optimization: Use down-milling strategies to reduce tool wear, and process deep holes or complex cavities in stages to avoid stress concentration.

Quality Assurance System

The factory ensures part consistency through standardized processes:

● Material Traceability: Provide material report

● Process Monitoring: CNC machining compensates tool wear in real time, three-coordinate detection of key dimensions (±0.01mm)

Industrial Applications and Market Positioning

Precision copper parts play a key role in many fields:

Electrical and Electronics: Copper is used for high-voltage cables and connectors to ensure efficient conductivity.

Automotive and Aerospace: Aluminum bronze bearings and nickel silver sensor components meet the needs of lightweight and high temperature resistance.

Medical Equipment: Nickel silver instrument components are widely used due to their non-magnetic and corrosion-resistant properties.
