Overview
Kormax 385 brass comes in a range of bars, tubes, and rounds – including angle bars. Great for architectural and tooling usage, this metal is closely monitored throughout its extrusion to ensure the material is always up to the highest specifications.
385 has been developed for use where maximum machinability and longest tool life are essential. All extrusions are manufactured from continuous cast billet stock ensuring uniform dispersion of lead particles and freedom from porosity. Alloy 385 is susceptible to dezincification under certain conditions and is classified a category III alloy.
Kormax brass can be custom cut to your requirements.
