Understanding Nickel Alloy Flanges

What Are Nickel Alloy Flanges?

Nickel alloy flanges are made from materials that have nickel as the primary element, often combined with other elements like chromium, ütü, bakır, or molybdenum to enhance performance. These alloys are valued for their exceptional corrosion resistance and ability to perform in extreme environments.

Common Nickel Alloys Used for Flanges

• İnkonel (Alaşım 600, 625, 718): Yüksek mukavemet, oksidasyon direnci, and performance in high temperatures.

• Monel (Alaşım 400, K-500): Excellent resistance to seawater and strong acids.

• Hastelloy (C-22, C-276): Outstanding corrosion resistance in oxidizing and reducing environments.

• Nikel 200/201: Commercially pure nickel with excellent resistance to caustic solutions.

Understanding Copper Nickel Flanges

What Are Copper Nickel Flanges?

Copper nickel (Bizimle) flanges are made from alloys containing copper and nickel, typically in a ratio of 90-10 veya 70-30. These alloys offer excellent resistance to seawater corrosion and biofouling, making them ideal for marine applications.

Common Copper Nickel Grades

• 90/10 (C70600): 90% bakır, 10% nikel, with added iron for improved strength and corrosion resistance.

• 70/30 (C71500): 70% bakır, 30% nikel, offering superior strength and better resistance to high-velocity seawater.
