What Is The Difference Between 90-10 And 70/30 Copper Nickel Valve?

Copper and nickel come in a variety of grades to meet these properties. Copper and nickel grade is well known for their long-term performance in corrosive environments. Cupro Nickel 70-30 Valves oxidation resistance, the ability to oppose rusting and resist growth on its surface, has been ideal and successfully used for marine applications. However, the finest qualities for marine applications are provided by the combination of Copper Nickel 90/10 and 70/30. The 90/10 and 70/30 alloys have historically been utilized in the construction of ships. In seawater applications, they are, therefore, frequently used.
