Brass and copper are specified when conductivity, thermal performance or a specific appearance is part of the function — not just when a part needs to be strong.
Where they are used
Fluid and pneumatic fittings, manifolds and valve bodies, electrical contacts, terminals and busbars, heat-exchanger components, instrument parts, and decorative or architectural hardware.
Machining and appearance
Free-cutting brass produces fine chips and excellent finish, which keeps cycle times low and makes it a favourite for turned parts. Copper is softer and tends to gall, so tooling and speeds are adjusted, and parts are handled carefully to avoid marking.
Both materials polish well and plate readily with nickel, chrome or tin. Where the part will be seen, we polish and lacquer or plate to keep the appearance stable over time.
