Product Selection Differences for Rolled Aluminium Extrusions

When selecting rolled aluminum extrusions, there are several key factors to consider:

1. Alloy Type: Different aluminum alloys offer varying properties such as strength, corrosion resistance, and formability. Common alloys include 6061, 6063, and 7075, each suited for different applications.

2. Surface Finish: Rolled aluminum extrusions can have different surface finishes like mill finish, anodized, or powder-coated. Consider the desired appearance and level of protection needed for the application.

3. Tolerances: Accuracy in dimensions is crucial for ensuring the extrusions fit properly in the intended application. Check the tolerance levels provided by the manufacturer.

4. Strength and Hardness: Depending on the application, you may need extrusions with specific strength and hardness properties. Consider factors like tensile strength, yield strength, and hardness values.

5. Temper Designations: Aluminum extrusions are available in different tempers such as T4, T6, or T651, which affect the material's mechanical properties. Choose the temper that aligns with the performance requirements.

6. Customization Options: Some manufacturers offer customization options such as cutting to length, drilling, bending, or CNC machining. Consider whether such services are needed for your project.

7. Quality Certifications: Look for extrusion suppliers with quality certifications like ISO 9001 to ensure that the products meet industry standards for consistency and performance.

8. Supplier Reputation: Consider the reputation and track record of the extrusion supplier. Look for reviews, testimonials, and their experience in serving industries similar to yours.

By evaluating these factors, you can select the most suitable rolled aluminum extrusions for your specific application or project.
