Bending processing is a common metalworking method that can be used to process various types of profiles. Here are some common profiles that can undergo bending processing: 

1. Aluminum alloy profiles: Aluminum alloy profiles are one of the most commonly used materials in bending processing. Due to their good plasticity and strength, aluminum alloy profiles can easily undergo bending processing. Aluminum alloy profiles are widely used in construction, aviation, automotive, and other fields. 

2. Steel profiles: Steel profiles are also commonly used materials in bending processing. Steel profiles have high strength and good plasticity, so they can undergo various complex bending processes. Steel profiles are widely used in construction, bridges, ships, and other fields. 

3. Stainless steel profiles: Stainless steel profiles are another common material that can undergo bending processing. Stainless steel profiles have good corrosion resistance and strength, making them suitable for manufacturing various corrosion-resistant equipment and pipelines. 

4. Copper profiles: Copper profiles are also a common material that can undergo bending processing. Copper profiles have excellent electrical conductivity and thermal conductivity, making them suitable for manufacturing various electrical devices and heat exchangers. 

5. Titanium alloy profiles: Titanium alloy profiles are a high-strength, lightweight material suitable for manufacturing various aerospace equipment and medical devices. 

In addition to the above common profiles, there are other special materials that can undergo bending processing, such as magnesium alloy profiles and nickel-based alloy profiles. In summary, bending processing can be used to process various types of profiles to meet the needs of different fields and customers.
