CDA 360 brass is a free-machining brass alloy containing approximately 61.5% copper and 35.5% zinc, with small additions of lead (around 3%) that significantly enhance its machinability. Also known as “free-cutting brass” or “screw machine brass,” this alloy is designated as UNS C36000 in the Unified Numbering System and is widely used in high-speed machining operations.
The lead content in CDA 360 acts as a natural lubricant during machining, creating short, easily broken chips and reducing tool wear. This makes it ideal for automatic screw machines, turret lathes, and other high-production machining equipment. The alloy exhibits excellent cold workability and good hot formability, though the lead content makes it unsuitable for welding or applications requiring high corrosion resistance in certain environments.
Key properties of CDA 360 include a tensile strength of approximately 55,000-70,000 psi, yield strength of 20,000-60,000 psi (depending on temper), and an elongation of 53-68%. It has good electrical conductivity (about 26% IACS), moderate corrosion resistance, and a density of 8.5 g/cm³. The alloy work-hardens moderately and can be supplied in various tempers from annealed to hard.
Equivalent grades internationally include DIN CuZn39Pb3 (Germany), BS CZ121 (UK), JIS C3604 (Japan), and AFNOR CuZn39Pb3 (France). Similar free-machining brasses include CDA 353 (62% Cu, 35.25% Zn, 2.5% Pb) and CDA 377 (60% Cu, 38.5% Zn, 1.25% Pb), which offer slightly different lead contents for specific machining requirements. These alloys are commonly used in plumbing fittings, electrical components, fast
CW614N is the European designation (EN 12163) for a free-machining brass alloy that is essentially equivalent to CDA 360 brass. The “CW” prefix indicates it’s a wrought copper-zinc alloy, “614” is the specific alloy number, and “N” denotes the standard condition or temper.

Frequently Asked Questions (Q&A)
CDA 360 and C36000 refer to the same Brass alloy designation under different naming conventions. CDA 360 is the Copper Development Association designation, while C36000 is the UNS (Unified Numbering System) designation. Both specify the same composition with approximately 61.5% Copper, 35.5% Zinc, and 3.0% Lead for enhanced machinability.
Lead is added to CDA 360 Brass to improve machinability by acting as a lubricant during cutting operations. The lead content creates small, easily broken chips, reduces cutting forces, extends tool life, and enables higher cutting speeds. This makes CDA 360 ideal for screw machine operations and high-volume production.
Due to lead content, CDA 360 components are not recommended for potable water applications in many regions. For drinking water systems, we recommend lead-free alternatives such as C36500 or consult with our technical team for appropriate alloy selection based on local regulations and application requirements.
Available surface treatments include passivation for enhanced corrosion resistance, nickel plating for improved wear resistance, chromium plating for decorative applications, and various protective coatings. Our technical team can recommend optimal treatments based on specific application requirements and environmental conditions.
Minimum order quantities vary based on component complexity and machining requirements. For standard components, MOQ typically starts at 100 pieces, while complex custom parts may require 500-1000 pieces. Prototype quantities and small batches can be accommodated with adjusted pricing and lead times.
We employ statistical process control (SPC) with real-time monitoring, coordinate measuring machines (CMM) for verification, automatic tool compensation systems, and regular calibration of all measuring equipment. Each production lot undergoes first article inspection and continuous sampling throughout the production cycle.
