Copper Alloy

Free-Machining Brass C36000

C360 free-cutting brass contains a small lead addition that makes it the benchmark for machinability: it is the reference material (rating 100) on the copper-alloy machinability scale. It is a natural fit for turned parts, fittings, and decorative hardware. Request a quote or browse all materials.

Ranges cover soft to half-hard rod tempers. Lead-free or low-lead brasses are available by request for regulated applications. These are typical reference values from standard published data, not guaranteed minimums. Request material certificates in your RFQ if properties must be verified.

Advantages

Why engineers choose Brass C360

Machinability

Very fast cycle times and excellent thread and knurl quality.

Corrosion

Good resistance in water and atmospheric service.

Electrical

Useful conductivity for connectors and terminals.

Appearance

Attractive gold tone that polishes well.

Design considerations: Lead content limits use in drinking-water and some consumer applications; lower strength than steel; can dezincify in certain waters.
