Cupro Nickel 70/30 Heat Exchanger Tubing can be exposed to high-temperature applications without a deformation, due to the high coefficient of thermal expansion. This alloy is composed of copper and nickel fittings in the 70/30 ratio. It has low creep rates under impact forces. Due to its high melting point so it is ideal for heating applications. This alloy is from the family of the austenitic grade. The copper alloy is magnetic and slightly non-magnetic in the state. This alloy serves brilliant service towards corrosion and abrasion containing environments. Moreover, this offers great resistance to pitting, crevice, stress corrosion cracking. These serve the best performance in reducing chemicals such as chlorides, sulfides, alkalis, sulfuric acids, nitric acids, phosphoric acids, and other harsh chemicals. This grade has great thermal conductivity.
