What is Aluminium Bronze AB2?
Aluminium Bronze AB2, often referred to by its UNS designation C95500 or standards like BS 1400 AB2, is a high-performance copper alloy renowned for its exceptional strength, hardness, and resistance to corrosion and wear. It's a specific type of bronze where aluminium is the primary alloying element, typically ranging from 9% to 11%. Other elements like iron and nickel are often added to further enhance its mechanical properties, making it a versatile material for demanding applications.
Who should use it: Engineers, designers, procurement specialists, and manufacturers working with components that require high mechanical strength, excellent wear resistance, and superior corrosion protection, especially in marine, chemical processing, and high-load mechanical environments. This includes applications like pump shafts, valve components, marine hardware, high-strength fasteners, and wear plates.
Common misconceptions: A common misconception is that all bronzes are similar. Aluminium Bronze AB2 is significantly stronger and harder than traditional tin bronzes. Another misconception is that its high strength comes at the expense of ductility; while it's strong, it still possesses adequate ductility for many forming processes. Lastly, some may assume it's prone to dezincification like some brasses, but AB2 exhibits excellent resistance to this form of corrosion.
Aluminium Bronze AB2 Weight Calculation Formula and Mathematical Explanation
The fundamental principle behind calculating the weight of any material, including Aluminium Bronze AB2, is the relationship between its volume and its density. The formula is straightforward:
Weight = Volume × Density
Let's break down the components:
Volume (V): This is the three-dimensional space occupied by the Aluminium Bronze AB2 component. The method for calculating volume depends entirely on the shape of the component. For standard shapes like rods, sheets, or tubes, geometric formulas are used. For irregular shapes, more complex methods like 3D modeling or displacement techniques might be necessary, or the user can input the total calculated volume directly.
Density (ρ): This is an intrinsic property of the material, representing its mass per unit volume. For Aluminium Bronze AB2 (C95500), the density is approximately 7.65 grams per cubic centimeter (g/cm³). This value is crucial and is often provided by material suppliers or can be found in material property databases.
Unit Conversion: It's vital to ensure consistent units. The calculator typically works with millimeters (mm) for dimensions and g/cm³ for density. The final weight is often desired in kilograms (kg). The density value of 7.65 g/cm³ is equivalent to 7650 kg/m³. The calculator handles these conversions internally.

Practical Examples (Real-World Use Cases)
Understanding the weight of Aluminium Bronze AB2 is critical for logistics, structural integrity, and cost management. Here are two practical examples:
Example 1: Marine Propeller Shaft Component
A marine engineering firm needs to estimate the weight of a solid cylindrical component for a propeller shaft made of Aluminium Bronze AB2. The component has a diameter of 150 mm and a length of 500 mm.
Convert Weight to kg: 67592.3 g / 1000 g/kg ≈ 67.6 kg
Output: The estimated weight of the Aluminium Bronze AB2 component is approximately 67.6 kg.
Interpretation: This weight is crucial for handling, transportation, and ensuring the supporting structures can bear the load. It also forms a basis for material cost estimation.
Example 2: Wear Plate for Industrial Machinery
A manufacturing plant requires a rectangular wear plate made from Aluminium Bronze AB2 to protect a critical machine part. The plate dimensions are 300 mm width, 600 mm length, and 20 mm thickness.
Convert Weight to kg: 27540 g / 1000 g/kg = 27.54 kg
Output: The estimated weight of the Aluminium Bronze AB2 wear plate is approximately 27.54 kg.
Interpretation: Knowing this weight helps in specifying the correct mounting hardware and assessing the overall weight contribution to the machinery. It also aids in ordering the precise amount of material needed, minimizing waste.

Key Factors That Affect Aluminium Bronze AB2 Results
While the core calculation (Weight = Volume × Density) is simple, several factors influence the accuracy and application of the results:
Dimensional Accuracy: The precision of your input measurements (diameter, length, width, thickness) directly impacts the calculated volume and, consequently, the weight. Manufacturing tolerances mean actual parts may vary slightly.
Material Density Variations: Although 7.65 g/cm³ is standard for AB2, slight variations can occur due to specific alloy compositions (e.g., minor differences in iron, nickel, or aluminium content) or manufacturing processes. Always refer to the specific material certification if high precision is required.
Shape Complexity: The calculator handles basic geometric shapes. For complex, machined, or cast parts with intricate features, the actual volume might differ significantly from simple geometric approximations. Using a CAD model for volume calculation is more accurate for such cases.
Internal Defects: Porosity, voids, or inclusions within the material can reduce the actual density and mass of a component compared to the calculated weight based on external dimensions. This is particularly relevant for cast parts.
Temperature Effects: While density is relatively stable, significant temperature changes can cause thermal expansion or contraction, slightly altering dimensions and thus volume. This is usually a minor factor unless operating in extreme temperature environments.
Surface Treatments/Coatings: If the Aluminium Bronze AB2 component is coated (e.g., plating, painting) or has a surface treatment that adds significant mass, this weight is not included in the base material calculation. The calculator provides the weight of the Aluminium Bronze AB2 material only.
Machining Allowances: If you are calculating the weight of raw material needed for a part that will be machined, remember to account for the material that will be removed (the "machining allowance"). The calculator provides the weight of the final component based on its final dimensions.
Frequently Asked Questions (FAQ)
What is the standard density of Aluminium Bronze AB2?
The standard density for Aluminium Bronze AB2 (C95500) is approximately 7.65 grams per cubic centimeter (g/cm³), which is equivalent to 7650 kg/m³.
Can this calculator be used for Aluminium Bronze grades other than AB2?
The calculator uses a fixed density value specific to AB2 (7.65 g/cm³). While the formulas for volume and weight remain the same, you would need to adjust the density input if calculating for a different grade of aluminium bronze with a different standard density.
What units should I use for the dimensions?
For consistency and accuracy with the calculator's internal calculations, please enter all dimensions (diameter, length, width, thickness) in millimeters (mm). The volume should be entered in cubic millimeters (mm³) if using the custom volume option.
How accurate is the weight calculation?
The accuracy depends primarily on the precision of your input dimensions and the consistency of the material's density. For standard shapes and certified materials, the calculation is highly accurate. For cast parts or components with complex geometries, it serves as a very good estimate.
Does the calculator account for hollow shapes other than tubes?
The calculator specifically includes a "Tube" option which calculates weight based on outer and inner diameters. For other hollow shapes, you would need to calculate the volume of the material manually (e.g., by subtracting the internal void volume from the external volume) and use the "Custom Volume" input.
What is the difference between Aluminium Bronze AB2 and other bronzes?
Aluminium Bronze AB2 is distinguished by its primary alloying element being aluminium (typically 9-11%), which imparts superior strength, hardness, and corrosion resistance compared to traditional tin bronzes. It excels in demanding applications where these properties are critical.
Can I calculate the weight of a casting using this tool?
Yes, if you know the final dimensions of the casting and select the appropriate shape (or use custom volume), the calculator will provide an estimated weight. However, be aware that porosity in castings can lead to a slightly lower actual weight than calculated.
What does the "Material Factor" represent?
The "Material Factor" is often a simplified value derived from the density or other material properties. In this calculator, it's primarily linked to the density (e.g., density in kg/dm³ or a similar normalized value) to provide a quick reference point for material comparison.
