Copper Nickel 70/30 Plates | UNS C71500 Plate | ASTM B171 C71500 Copper Nickel Plate Supplier

Copper Nickel 70/30 Plates Supplier, Manufacturer & Stockist

We are a trusted Copper Nickel 70/30 Plate Supplier serving customers across diverse industrial sectors worldwide. Our inventory includes premium-quality Copper Nickel 70/30 Plates, cupro nickel 70/30 sheets, 70/30 CuNi plate, and Copper Nickel 70/30 sheet plate manufactured according to international quality standards.

The UNS C71500 Plate is one of the most widely used copper-nickel alloys for marine and industrial environments where exceptional corrosion resistance is essential. The addition of iron and manganese significantly improves the alloy’s resistance to seawater erosion, making it ideal for demanding offshore applications.

Whether you require standard dimensions or custom-cut plates, we provide materials that undergo strict quality inspections to ensure excellent dimensional accuracy, mechanical strength, and long service life.

What is Copper Nickel 70/30 Plate?

Copper Nickel 70/30 Plate is a copper-based alloy containing approximately:

• 70% Copper
• 30% Nickel
• Small additions of Iron
• Manganese

This composition offers excellent resistance against:

• Seawater corrosion
• Marine organisms and biofouling
• Stress corrosion cracking
• Cavitation
• Chloride attack
• Erosion corrosion

The alloy also retains excellent thermal conductivity, weldability, fabrication characteristics, and mechanical strength, making it suitable for highly corrosive environments.

Key Features of Copper Nickel 70/30 Plates

Our Copper Nickel 70/30 Plates provide numerous performance advantages:

• Outstanding seawater corrosion resistance
• Excellent resistance to biofouling
• Superior erosion resistance
• High mechanical strength
• Excellent weldability
• Long service life
• Good thermal conductivity
• Excellent fabrication properties
• Reliable performance in chloride environments
• Low maintenance requirements

These characteristics make CuNi30Fe1Mn Plate 2.0882 one of the preferred materials for marine engineering and offshore industries.
