Standard metric sizes for aluminum angle stock typically include the following dimensions, which are measured in millimeters (mm): 1. **Equal Angles**: - 20 x 20 x 3 - 25 x 25 x 3 - 30 x 30 x 3 - 40 x 40 x 3 - 50 x 50 x 5 - 60 x 60 x 6 - 75 x 75 x 6 - 80 x 80 x 8 - 100 x 100 x 10 2. **Unequal Angles**: - 30 x 20 x 3 - 40 x 20 x 3 - 50 x 30 x 3 - 60 x 40 x 4 - 80 x 60 x 6 - 100 x 50 x 6 - 120 x 80 x 8 - 150 x 100 x 10 These sizes represent the width of each leg of the angle and the thickness of the material. The first two numbers indicate the lengths of the legs, and the third number indicates the thickness. For example, a 50 x 50 x 5 angle has two 50 mm legs and a thickness of 5 mm. These sizes can vary slightly depending on the manufacturer and regional standards, but the above dimensions are commonly available in the market. Aluminum angle stock is used in various applications, including structural frameworks, supports, and brackets, due to its lightweight and corrosion-resistant properties.

To calculate the weight of metric aluminum angle stock, follow these steps: 1. **Determine the Dimensions**: Identify the dimensions of the aluminum angle, including the leg lengths (A and B), thickness (T), and length (L) of the angle stock. These measurements should be in millimeters (mm) for metric calculations. 2. **Calculate the Cross-Sectional Area**: Use the formula for the cross-sectional area of an angle: \[ \text{Area} = A \times T + B \times T - T \times T \] This accounts for the two legs and subtracts the overlapping area at the corner. 3. **Convert to Square Meters**: Convert the cross-sectional area from square millimeters to square meters by dividing by 1,000,000. 4. **Determine the Volume**: Multiply the cross-sectional area (in square meters) by the length (L) of the angle stock (in meters) to get the volume in cubic meters. 5. **Find the Density of Aluminum**: The density of aluminum is approximately 2,700 kg/m³. 6. **Calculate the Weight**: Multiply the volume by the density to find the weight in kilograms: \[ \text{Weight} = \text{Volume} \times \text{Density} \] This process will give you the weight of the aluminum angle stock in kilograms. Adjust the units as necessary if you need the weight in different units.

Metric aluminum angle stock is commonly used in various applications due to its strength, lightweight nature, and resistance to corrosion. Here are some of its common applications: 1. **Construction and Architecture**: Used for structural support in frameworks, trusses, and bridges. It is also employed in architectural designs for aesthetic purposes, such as trim and edging. 2. **Fabrication and Manufacturing**: Utilized in the creation of machinery, equipment, and custom metal parts. Its versatility allows for easy cutting, welding, and forming into desired shapes. 3. **Automotive and Aerospace**: Employed in the production of vehicle frames, supports, and components due to its lightweight properties, which contribute to fuel efficiency and performance. 4. **Furniture and Interior Design**: Used in the construction of furniture frames, shelving units, and decorative elements. Its clean lines and modern look make it popular in contemporary designs. 5. **Marine Applications**: Ideal for boat building and marine structures because of its resistance to corrosion from saltwater. 6. **Electrical and Electronics**: Used in the fabrication of enclosures, brackets, and supports for electrical components and systems. 7. **DIY Projects and Home Improvement**: Popular among hobbyists and DIY enthusiasts for creating custom projects, repairs, and home improvements due to its ease of use and availability. 8. **Signage and Display**: Used in the construction of sign frames and display stands, providing durability and a professional appearance. 9. **Renewable Energy**: Employed in the construction of solar panel frames and wind turbine components, benefiting from its strength and resistance to environmental factors. 10. **Agriculture**: Used in the construction of equipment, fencing, and storage solutions, offering durability and resistance to weather conditions.

Metric aluminum angle stock is measured in millimeters (mm) for both the leg lengths and thickness, while imperial measurements use inches. For example, a metric angle might be specified as 50mm x 50mm x 5mm, indicating two 50mm legs with a 5mm thickness. In contrast, an imperial angle might be 2" x 2" x 1/4", with two 2-inch legs and a 1/4-inch thickness. When comparing the two, 1 inch is approximately 25.4mm. Therefore, a 50mm x 50mm x 5mm metric angle is roughly equivalent to a 2" x 2" x 0.197" imperial angle. However, exact matches are rare due to the different standard sizes available in each system. Metric sizes offer more precision due to smaller increments, which can be beneficial for specific engineering applications. Imperial sizes are often used in regions like the United States, where the imperial system is standard. In terms of availability, metric sizes might be less common in regions that predominantly use the imperial system, potentially affecting cost and lead time. Conversely, in regions where the metric system is standard, metric sizes are more readily available. Overall, the choice between metric and imperial aluminum angle stock depends on the project's location, the precision required, and the existing standards in the industry or region.
