These rods have been advantageous in preventing biocide dosing in the condenser or other piping applications.


Cu 70/30 Hex Bars is known for its moderate strength, formability, workability, and weldability in the application where high oxidation resistance is needed. These rods offer excellent resistance to erosion that is relative to stress corrosion. These rods possess different properties hence it is suitable for different applications.


These grade rods may be hot and cold forged. In short, these are also treated with metal refinement process that overcomes its structural defects and strengthens the rods.
