CuAl10Fe5Ni5 (C95500/CC333G)

The Ultimate Guide to CuAl10Fe5Ni5 (C95500/CC333G): The High-Strength Hero of Alloys

In the demanding world of engineering and manufacturing, material selection can make or break a project. When faced with extreme pressure, heavy loads, and corrosive environments, standard materials often fall short. This is where a champion emerges: CuAl10Fe5Ni5, a nickel aluminum bronze that offers a formidable combination of strength, durability, and corrosion resistance.

Whether you know it by its EN designation 2.0975, its UNS code C95500, or its continuous casting standard CC333G, this alloy is a go-to solution for critical components like bearing bushings and collar bushes.

But what makes this alloy so special? Let’s dive deep into its composition, properties, and applications to understand why it’s a top choice for engineers worldwide.

 Decoding the Name: What is CuAl10Fe5Ni5?

At first glance, “CuAl10Fe5Ni5” looks like a complex chemical formula. In reality, it’s a highly descriptive name that tells you its core ingredients. Let’s break it down:

• Cu (Copper): The base metal, providing excellent thermal and electrical conductivity, and forming the foundation of the alloy.

• Al10 (Aluminum ~10%): The primary alloying element. The addition of aluminum is what transforms copper into a high-strength bronze.

• Fe5 (Iron ~5%): Acts as a grain refiner. It prevents the formation of large, brittle crystals, resulting in a finer, tougher, and stronger microstructure.

• Ni5 (Nickel ~5%): The secret weapon. Nickel significantly improves the alloy’s strength and, most importantly, its corrosion resistance, especially in saltwater and acidic environments.

To simplify its various international names, here’s a quick reference table:

This cross-referencing is crucial for procurement and engineering teams working on international projects, ensuring material consistency across borders.

[H2] The Core Properties: Why Choose CuAl10Fe5Ni5?

CuAl10Fe5Ni5 isn’t just a mixture of metals; it’s an engineered material designed for performance. Its properties are a direct result of its unique chemical composition.

1. High Mechanical Strength & Hardness

The combination of aluminum, iron, and nickel gives this bronze exceptional mechanical properties that rival some steels. It exhibits high tensile strength and yield strength, allowing it to withstand heavy loads and high pressures without deforming. This makes it a perfect material for heavy-duty bearing bushings that operate under significant stress.

2. Unbeatable Corrosion Resistance

This is where CuAl10Fe5Ni5 truly shines. When exposed to the atmosphere or seawater, the aluminum in the alloy forms a thin, tough, and self-healing layer of aluminum oxide (Al₂O₃) on the surface. This invisible shield passivates the material, protecting the underlying bronze from attack.

• Seawater Immunity: It shows negligible corrosion rates in marine environments, making it ideal for naval applications, offshore oil rigs, and desalination plants.

• Chemical Resistance: It also resists many industrial chemicals and acids, expanding its use in the chemical processing industry.

3. Excellent Wear, Abrasion, and Fatigue Resistance

Components in motion, like bushings and gears, are subject to constant friction and cyclical loading. CuAl10Fe5Ni5’s inherent hardness and tough microstructure give it superior resistance to wear and abrasion. Furthermore, its high fatigue strength means it can endure millions of load cycles without failing, ensuring long service life and reliability.

[H2] Comparative Analysis: C95500 vs. Standard Bearing Bronze (C93200)

To truly appreciate the advantages of CuAl10Fe5Ni5 (C95500), let’s compare it to a more traditional bearing material, C93200 (Leaded Tin Bronze). This contrasting logic makes the choice clear.

This table clearly illustrates that while C93200 has its place, CuAl10Fe5Ni5 is the undisputed choice for applications demanding high strength and corrosion-proof performance.
