B30/C71500 Wrought Nickel-Copper Alloy: Engineered for Marine Excellence and Durability

In the demanding world of marine engineering and industrial applications, material selection is paramount. Components must withstand constant exposure to corrosive seawater, high pressures, and mechanical stress. This is where premium alloys like B30, also known as C71500 or BFe30-1-1, rise to the challenge. As a leading supplier, we specialize in providing high-quality wrought nickel-copper alloy forgings, including flanges and custom shapes, designed to deliver unmatched performance and longevity.

Nickel-copper alloys, often referred to as cupronickel, represent a critical category of materials prized for their excellent corrosion resistance, good fabricability, and reliable mechanical properties. Our B30/C71500 forgings, produced by the renowned brand Wocheng (沃乘) in Jiangsu, China, are manufactured to the highest standards using advanced forging (锻压) processes. Forging ensures a refined grain structure, enhanced mechanical strength, and superior integrity compared to cast alternatives, making it the ideal choice for critical marine components.

Key Specifications and Properties of BFe30-1-1 Alloy

Understanding the technical data is crucial for engineers and procurement specialists. Our product, identified by item code WC71500, boasts a precise chemical composition and physical characteristics:

• Common Names: Nickel-Copper Alloy, B30, C71500, Iron White Copper (铁白铜).
• Grade: Bfe30-1(Fe)-1(Mn).
• Copper Content: Remainder (余量), forming the base of the alloy.
• Nickel & Iron: Approximately 30% Nickel and 1% Iron, significantly boosting corrosion and erosion resistance.
• Impurity Content: A remarkably low 0.1%, ensuring purity and consistency.
• Softening Temperature: ~890°C, indicating good thermal stability.
• Conductivity: 48% IACS, offering decent electrical and thermal conductivity for an alloy.
• Hardness: 98 HB, providing a balance of machinability and wear resistance.

Why Choose Forged B30/C71500 Components?

The forging process is a game-changer. It aligns the grain flow of the metal to the shape of the part, resulting in:

• Increased Strength and Toughness: Superior resistance to impact and fatigue.
• Enhanced Structural Integrity: Elimination of internal voids and porosity common in castings.
• Excellent Surface Finish: Coupled with a final polishing treatment, our forgings offer a smooth surface that minimizes friction and fouling in marine environments.

These attributes make our wrought nickel-copper forgings perfect for marine flanges, valve bodies, pump components, condenser tubesheets, and other critical fittings where failure is not an option.

Applications: Where Performance Meets the Elements

The primary domain for B30/C71500 is anywhere corrosion is a primary concern. Its stellar performance in seawater is legendary.

• Shipbuilding & Offshore Platforms: Seawater piping systems, heat exchanger components, propeller shafts, and deck fittings.
• Desalination Plants: Essential for evaporator and condenser tubes and parts exposed to high-salinity water.
• Power & Chemical Processing: Suitable for components handling brackish cooling water and certain chemical solutions.
• High-Reliability Industrial Systems: Where long service life and minimal maintenance are required.
