Brass & copper alloys

#technical & durable

Copper alloys—including bronze, brass, nickel silver, and pure copper—are a material of choice in the Meunidec workshop. Their excellent machinability, thermal and electrical conductivity, as well as their good corrosion resistance make them indispensable for the production of precision parts.

Used in sectors such as electronics, construction, aerospace, energy, and plumbing, copper-based alloys combine technical performance, aesthetics, and durability. Whether for electrical contacts, hydraulic components, or decorative parts, these materials meet a wide range of functional and standards-based requirements.

 

At Meunidec, we have mastered the precision turning of copper alloys in small and medium series, based on our clients’ designs. Thanks to our expertise in CNC machining and our versatile machinery, we produce reliable and compliant parts with high-quality surface finishes.

Why choose a copper alloy for your machined parts?

Because it combines performance, aesthetics, and ease of machining. Copper-based alloys allow for optimized machining cycles, reduce tool wear, and offer excellent mechanical and chemical properties to suit your needs.

We assist you with:

  • The choice of alloy (bronze, brass, copper, nickel silver, etc.) that’s best for your specific business constraints
  • Defining your tolerances, potential treatments, and surface finishes
  • Reliable, fast, and controlled production that respects your specifications

✔ Advantages :

  • Excellent machinability: These materials are easy to machine, making them perfect for precision turning.

  • Good corrosion resistance: Ideal for humid or saline environments (plumbing, marine, etc.).

  • Conductive properties: Excellent electrical and thermal conductors (especially for copper).

  • Aesthetic appeal: Features warm, golden, or silvery hues, making them perfect for visible or designer parts.

  • Naturally antibacterial: Beneficial for sensitive industries (medical, food, etc.).

⚠ Limitation :

  • Sensitivity to certain chemical agents: Particularly to ammonia or strong acids.

  • Variable cost: Certain grades (pure copper, tin bronze) can be expensive.

  • Varying mechanical properties: Some alloys are less resistant to shock or wear.

Most Common Copper Alloys Used in Precision Machining

  • Brass (CuZn39Pb3, CuZn40Pb2): Excellent machinability, widely used in plumbing and connectors.
  • Bronze (CuSn12, CuAl10Fe5Ni5): Wear resistance, good performance in saline or abrasive environments.
  • Pure Copper (Cu-ETP, Cu-OFE): Maximum conductivity, ideal for electrical and electronic applications.
  • Nickel Silver (CuNiZn): Beautiful silver appearance, good mechanical and corrosion resistance.

Typical Applications of Copper Alloys in Precision Machining

  • Electrical & Electronics: Terminals, connectors, and heat dissipation components.
  • Plumbing & Sanitary: Fittings, bushings, and components in contact with drinking water.
  • Instrumentation & Watchmaking: Decorative parts, gears, and axles.
  • Aerospace & Defense: Components resistant to corrosion and high temperatures.
  • Medical Equipment: Antibacterial parts and precision components.
