Properties
Brass is a metal alloy primarily composed of copper and zinc, known for its excellent malleability, corrosion resistance, and attractive gold-like appearance. It is commonly used in musical instruments, decorative objects, and plumbing fixtures due to its acoustic properties and aesthetic appeal. Brass has a relatively low melting point, making it easy to shape and mold. It is also highly conductive of heat and electricity, making it a popular choice for electrical connectors and heat exchangers.
Parameters
Brass instruments are characterized by their bright, metallic sound. The main parameters of brass include material composition (usually a combination of copper and zinc), bell size, valve mechanism, and bore size. These factors determine the instrument's tone quality, projection, and overall playability. Additionally, the weight and shape of the instrument can impact a player's comfort and endurance during performance. Understanding these parameters is crucial for selecting the right brass instrument to suit a player's musical style and preferences.
Precautions
When machining Brass, ensure proper ventilation to prevent inhalation of fumes. Use coolant to avoid overheating and wear protective gear such as gloves and eye protection. Secure workpieces tightly to prevent shifting. Check for any defects or impurities in the material before starting. Follow proper machining procedures to avoid accidents and ensure quality results. Regularly maintain and clean machinery to prolong its lifespan. Always follow safety guidelines provided by the manufacturer.
Why Cooper is ideal for CNC machining?

Why Choose Brass C360?
Choose Brass C360 when you need a material that can withstand high-speed machining without sacrificing quality or efficiency. It’s especially valuable in automated screw machines, CNC lathes, and multi-axis milling setups where accuracy, speed, and surface quality are critical. Its balance of strength, machinability, and cost-efficiency makes it a preferred material across multiple industries—from electronics and plumbing to aerospace and automotive.
C360 Brass is the go-to material when maximum machinability, clean surface finishes, and cost-effective production are priorities—particularly in automated machining environments. Leaded brass alloys are copper-zinc alloys with small additions of lead (typically 1–3%). The lead enhances machinability by acting as a chip breaker and lubricant, making these alloys ideal for high-speed, high-precision machining processes like CNC turning and screw machining.
