What is Cu-Ni 70/30 Flanges ?
Copper nickel 70/30 flanges are manufactured using high quality equipment. These flanges are commonly used for joining two or more joints together. These copper nickel 70/30 flanges are made with excellent quality raw material and superior technology.
ASTM/ASME SB 61/62/151/152 Cu-Ni 70/30 flanges are heavily alloyed with elements like copper and nickel. The combination includes 70% content of copper and 30% content of nickel. The nickel and copper provides excellent strength and robustness to the grade. ASTM/ASME SB 61/62/151/152 Cu-Ni 70/30 Flanges also includes small amounts of lead, manganese, zinc and iron. These elements are generally added to provide stability and efficiency to the grade.
These flanges are amazingly enriched with excellent properties and characteristics. ASTM/ASME SB 61/62/151/152 Cu-Ni 70/30 Flanges provide resistance from various chemical and physical reactions.
