C3601/C3602

C3601 and C3602 are free-machining brass alloys known for their excellent machinability, strength, and corrosion resistance. Both alloys contain copper, zinc, and lead, and are widely used in precision machining applications requiring tough, durable components.

C3601 Description and Composition

C3601 brass features high machinability due to dispersed lead particles, making it ideal for CNC and automatic lathe machining. It has strength and corrosion resistance similar to steel and can be precision machined easily. The alloy forms a protective patina that prevents rusting, offering good density for heavy industrial parts and a polished finish. Available in rounds, flats, squares, hexagons, tubes, plates, and sheets.

• Copper (Cu): 59.00–63.00%

• Lead (Pb): 1.80–3.70%

• Iron (Fe): Max 0.30%

• Tin + Iron (Sn+Fe): Max 0.50%

• Zinc (Zn): Remainder

C3602 Description and Composition

C3602 is a variant of free-machining brass with slightly modified composition to improve ductility and cut quality. It has a lead content designed to improve expansibility and is suitable for bending, crimping, and machining operations such as for bend valves and machine parts. The alloy maintains good corrosion resistance and strength properties.

• Copper (Cu): 59.00–63.00%

• Lead (Pb): 1.80–3.70%

• Tin + Iron (Sn+Fe): Max 1.20%

• Iron (Fe): Max 0.30%

• Zinc (Zn): Remainder

Both alloys are well-suited for precision machined components in automotive, plumbing, electrical, and industrial applications, offering a balance of strength, machinability, and corrosion resistance.
