Unlocking Peak Performance: A Deep Dive into CuAl11Fe6Ni6-C (DIN 2.0980) Bronze Plain Bearings & CNC Machined Blocks
In the demanding world of engineering, material selection is paramount. When applications call for exceptional strength, superior wear resistance, and robust corrosion defense, especially under heavy loads or in harsh environments, standard materials often fall short. This is where high-strength aluminum bronzes like CuAl11Fe6Ni6-C (DIN 2.0980) step into the spotlight.
At viiplus.com, if applicable, otherwise omit], we don’t just supply this remarkable alloy; we leverage its potential through precision CNC machining to deliver custom plain bearings (bushings), blocks, plates, and intricate components tailored to your exact specifications.
Let’s break down why CuAl11Fe6Ni6-C is more than just another bronze.
Understanding CuAl11Fe6Ni6-C (DIN 2.0980): Beyond the Basics
CuAl11Fe6Ni6-C, also known by its EN designation CW308G, is a nickel-aluminum bronze. The “C” at the end of the DIN designation often indicates a continuously cast product, which typically results in a finer grain structure and improved mechanical properties compared to other casting methods.
The Power is in the Composition:
The specific alloying elements are not just randomly thrown in; each plays a crucial role in defining the material’s outstanding characteristics.
| Element | Approximate % | Key Contribution |
| Copper (Cu) | Balance | Base metal; provides good thermal and electrical conductivity (though lower than pure copper due to alloying). |
| Aluminum (Al) | ~11% | Primary strengthener. Forms a tenacious, self-healing aluminum oxide (Al₂O₃) surface layer, providing excellent corrosion and oxidation resistance. Increases hardness and wear resistance. |
| Iron (Fe) | ~6% | Acts as a grain refiner, leading to improved mechanical strength (tensile and yield) and toughness. Enhances wear resistance. |
| Nickel (Ni) | ~6% | Improves overall strength and toughness, particularly at elevated temperatures. Significantly enhances corrosion resistance, especially in marine environments and against certain acids. Stabilizes the beneficial phases within the bronze. |
This carefully balanced cocktail of elements results in a material that significantly outperforms many traditional bronzes and even some steels in specific scenarios.
Key Features & Why They Matter:
-
High Load Capacity & Mechanical Strength:
-
Tensile Strength: Typically in the range of 750-850 MPa (or higher, depending on temper and casting method).
-
Yield Strength: Around 380-450 MPa.
-
Hardness: Often exceeding 200 HB (Brinell Hardness).
-
Why it matters: These figures mean the material can withstand significant forces without deforming or fracturing, making it ideal for components under high stress.
-
-
Excellent Resistance to Wear & Abrasion:
-
The combination of hardness imparted by aluminum and nickel, along with the fine grain structure from iron, makes this alloy highly resistant to frictional wear, galling, and abrasion.
-
Why it matters: Longer component life, reduced maintenance intervals, and reliability in moving parts, especially under high contact pressures or with less-than-ideal lubrication.
-
-
Superior Corrosion Resistance:
-
The aluminum content forms a passive, protective aluminum oxide layer on the surface. Nickel further enhances this, especially against seawater, brackish water, and many industrial chemicals.
-
Why it matters: Ideal for marine applications, chemical processing equipment, and anywhere the environment is aggressive. It resists dezincification and stress corrosion cracking far better than many brasses and some other bronzes.
-
-
Good Performance at Elevated Temperatures:
-
Nickel and iron help retain strength and resist oxidation at higher operating temperatures compared to standard tin or leaded bronzes.
-
Why it matters: Suitable for applications like molds, dies, and components near heat sources where other materials might soften or degrade.

Contrasting Logic: CuAl11Fe6Ni6-C vs. Other Common Bronzes
To truly appreciate CuAl11Fe6Ni6-C, let’s compare it to more common bronze alloys:
| Feature | CuAl11Fe6Ni6-C (DIN 2.0980) | Standard Tin Bronze (e.g., C90700/SAE 65) | Leaded Tin Bronze (e.g., C93200/SAE 660) |
| Primary Alloying | Aluminum, Iron, Nickel | Tin | Tin, Lead |
| Tensile Strength | Very High (750-850 MPa) | Moderate (300-350 MPa) | Low-Moderate (240-280 MPa) |
| Yield Strength | High (380-450 MPa) | Moderate (150-180 MPa) | Low-Moderate (120-140 MPa) |
| Hardness (Brinell) | High (190-230 HB) | Moderate (75-90 HB) | Low-Moderate (60-70 HB) |
| Wear Resistance | Excellent | Good | Fair (Lead aids lubricity but lowers wear res.) |
| Corrosion Resistance | Excellent (esp. seawater, acids) | Good (general) | Moderate (Lead can be an issue) |
| Anti-Galling | Good | Good | Excellent (due to Lead) |
| Machinability | More Challenging (needs rigid setup, sharp tools) | Good | Excellent |
| Typical Use Case | Heavy loads, high wear, corrosive env. | General purpose bearings, gears | Bearings needing self-lubrication, good embeddability |
Key Takeaway: While leaded bronzes offer excellent anti-friction properties for certain bearing applications and tin bronzes are good all-rounders, CuAl11Fe6Ni6-C is the champion for applications demanding the utmost in strength, wear resistance, and corrosion defense. Its slightly more challenging machinability is a small trade-off for its significantly enhanced performance envelope.
