4. 6061:This popular alloy offers a balance of strength, corrosion resistance, and machinability. It is commonly used in structural applications, such as frames and brackets.
5. 7075:With added zinc for increased strength, this high-strength alloy is used in aerospace and military applications due to its excellent fatigue resistance and strength-to-weight ratio.
Fabrication Techniques
There are various techniques used in aluminum sheet metal fabrication, each suited for specific applications and desired outcomes. Some of the most common methods include:
Cutting
Cutting is the process of separating the aluminum sheet into smaller pieces or desired shapes. Common cutting techniques include:
1. Shearing:A shearing machine uses a large blade to make straight-line cuts in the aluminum sheet.
2. Laser cutting:A high-powered laser beam is used to make precise cuts in the aluminum sheet, offering excellent accuracy and minimal material waste.
3. Plasma cutting:A plasma torch uses an electrically charged gas to cut through the aluminum sheet, offering high cutting speeds and the ability to cut thicker materials.
Bending
Bending is the process of shaping the aluminum sheet by applying force along a specific axis. Common bending techniques include:
1. Press braking:A press brake machine uses a punch and die to bend the aluminum sheet along a specific axis.
2. Roll forming:A series of rollers are used to gradually bend the aluminum sheet into the desired shape, such as a curve or a tube.
Joining
Joining is the process of connecting multiple pieces of aluminum sheet metal to form a single product. Common joining techniques include:
1. Welding:Welding uses heat and pressure to fuse the aluminum sheets together, creating a strong bond.
2. Riveting:Rivets are used to mechanically fasten the aluminum sheets together, offering a secure and long-lasting connection.
3. Adhesive bonding:A strong adhesive is used to bond the aluminum sheets together, providing a clean and seamless appearance.
