Advantages Of Aluminum Alloy Forgings And Other Manufacturing Methods (Part 2)

(2) aluminum forgings vs extrusion

Advantages of aluminum forgings:

1. Higher mechanical performance:

Forging refines grain size through plastic deformation, improves material strength and toughness, and is suitable for manufacturing high load parts.

2. More complex shapes:

Forging can produce parts with complex three-dimensional shapes, while extrusion is usually limited to two-dimensional cross-sectional shapes.

3. Better isotropy:

The mechanical properties of forgings are relatively uniform in all directions, while the performance of extruded parts may vary due to the streamline direction.

4. Suitable for high-precision parts:

Precision forging can produce parts with high dimensional accuracy and good surface quality, reducing subsequent processing.

Advantages of Squeezing:

1. High production efficiency:

The extrusion process is suitable for large-scale production, especially for parts with long strips or consistent cross-sectional shapes.

2. Low cost:

The material utilization rate of extrusion technology is high, and the mold cost is relatively low.

3. Suitable for thin-walled parts:

Extrusion can produce thin-walled and hollow profiles, suitable for lightweight design.

4. Good surface quality:

The surface of the extruded part is smooth and usually does not require further processing.

Summary:

aluminum forgings are superior to extruded parts in terms of mechanical properties and complex shape manufacturing, making them suitable for high load, high-precision parts.

Squeezing has advantages in high efficiency, low cost, and mass production, and is suitable for long or thin-walled parts.
