Severe corrosion of brass, also known as dezincification, can occur in environments containing chlorides and other deviating water qualities such as soft water. Stagnant or slow moving water can also corrode copper to a sponge-like surface with very poor mechanical properties. This can be virtually eliminated with Dezincification Resistant Alloys (DZR or DR brass).Also known as CR (corrosion resistant) brasses, DZR Brass is subject to careful control of time and temperature of heat treatment in production. Detailed attention is given to the type and quantity of alloying elements to control alpha and beta phases due to the vulnerability of beta phase to dezincification. In addition, attention must be given to the finished parts manufacturing process (machining or hot forging) so that the correct heat treatment can be applied to the material.Typical Applications:Plumbing FittingsValvesPropellersBearingsShafts

Naval Brass is a classic material for many applications in fresh and salt water environments. The addition of up to 1% tin inhibits the loss of zinc in many environments resulting in strong corrosion resistance properties. Good wear and fatigue resistance combined with excellent thermal conductivity and formability yield a brass alloy suitable for a wide range of marine and other difficult liquid environments.Typical Applications:Propeller ShaftsMarine HardwareValve StemsHeat Exchanger TubesBearingsTurn Buckles

One of our most satisfying products is achieved through the production of customer-designed brass profiles that greatly reduce secondary finishing by our customers. Quite complex raw material shapes are possible yielding readily finished brass parts for a wide variety of end products for anything from glass framing to door handles and hinges.Profile dimensions fitting within a circumference between 0.25 inch (6mm) and 4.75 inch (120mm) will be entertained for evaluation and quotation. Our sales team will be happy to work with you through drawing evaluation and production to reach the most efficient, accurate and cost effective product for your application.Typical Applications:Lock SectionsDoor Hinges and HandlesGlass FramingArchitectureSanitary Applications
