Metalline Products


Metalline Corporation manufactures a unique chemical immersion bright dip that will polish, de-burr and remove surface imperfections from brass and copper alloys. Listed below is a brief description of the AQUAPOLISH® process.

  • AQUAPOLISH® is an environmentally friendly alternative to conventional nitric/sulfuric bright dip formulations that does not contain nitric or chromic acid.  AQUAPOLISH® can be used to provide a highly polished final finish or as a pretreatment to nickel, tin or gold plating.  AQUAPOLISH® will polish and activate the surface of brass and copper alloys with minimal, often immeasurable metal removal.  AQUAPOLISH® is an easy to operate, easy to maintain, chemically stable process that does not require a cooling coil and does not contain any chelating agents.
