Tanvir Nickel Alloys, located in Cairo, Egypt, stands out as a leading manufacturer and supplier of top-notch Copper Nickel 70/30 Tubing, crafted for exceptional performance in demanding marine and industrial settings. With a commitment to precision and stringent quality control, these tubes adhere to international standards for corrosion resistance and mechanical strength. Serving industries like shipbuilding, offshore oil and gas, desalination, and chemical processing, Tanvir Nickel Alloys provides reliable tubing solutions that promise long-lasting durability even in the face of aggressive seawater and chemical exposure.
Copper Nickel 70/30 Tubing is made from an alloy that consists of about 70% copper and 30% nickel, with small amounts of iron and manganese added to boost its mechanical properties and corrosion resistance. This alloy is known for its impressive resistance to pitting, stress corrosion cracking, and biofouling in both seawater and brackish water environments. Typically, the tubing showcases a tensile strength ranging from 275 to 350 MPa and a yield strength between 105 and 150 MPa, along with good ductility and thermal stability. These characteristics ensure that the tubing maintains its integrity and performance even under high pressure and fluctuating temperatures.
