CW609N

CW609N is a free cutting forging brass alloy known for excellent machinability, strength, and corrosion resistance. It is commonly used in mass production parts for builder hardware components requiring good hot working capacity and durability.

Chemical Composition

• Copper (Cu): 57.00 – 59.00%

• Lead (Pb): 3.50 – 4.20%

• Iron (Fe): Up to 0.30%

• Tin (Sn): Up to 0.30%

• Nickel (Ni): Up to 0.30%

• Aluminium (Al): Up to 0.05%

• Other elements (total): Up to 0.20%

• Zinc (Zn): Remainder (balance)

Properties and Applications

• High machinability with lead acting as a lubricant and chip breaker

• Good corrosion resistance, suitable for builder hardware, gas fittings, valve bodies, plumbing fixtures, and industrial hardware

• Excellent hot workability; poor cold workability

• Suitable for soldering and brazing, welding is not generally recommended
