COPPER ALLOY TUBE & PIPE

COPPER ALLOY TUBE & PIPE

Thanks to great corrosion resistance characteristic, the copper and copper alloy tubes are widely used where the sea water used in the application such as Power plant, Petrochemicals and Desalination plant.

We, DUSUNG METAL, provides the best solutions to meet our customers' desired delivery times and prices based on our extensive experience, and we can suggest alternatives to our customers thanks to our long-standing expertise in material selection.

The grades we provide are

  1. Pure copper in pancake coil, straight tube for cooler and general industry (Mostly Korea, short lead time_ C12200, C11000, Brass tube etc
  2. Copper alloy grades (Korea, China origin mostly 4~6 weeks lead time) C44300, C68700 , C70600 , C71000, C71500, C71640
