Product Details

A 1/4 Inch Aluminum Plate (0.25 inch / 6.35 mm) is a medium-thickness aluminum material widely used in structural fabrication, transportation equipment, machinery parts, and industrial construction. Due to its relatively high stiffness, proper bending techniques are required to ensure accuracy and prevent cracking or deformation.

Aluminum Plate Bending Process

The bending process of a 1/4 inch aluminum plate depends on alloy type, temper, and required bend radius.

1. Material Preparation

Common alloys include 5052, 6061, and 3003
The plate surface must be clean and free of oxidation or oil
Soft tempers (such as O or H32) are easier to bend than T6 conditions

2. Bending Methods

(1) Press Brake Bending

Most common method for 1/4 inch aluminum plate
Uses a punch and die to apply controlled force
Suitable for straight bends and industrial components
Requires proper die selection to avoid cracking

(2) Roll Bending

Used for curved or cylindrical shapes
Plate passes through rollers to gradually form a curve
Ideal for tanks, ducts, and large-radius components

(3) CNC Controlled Bending

High precision bending using CNC press brake machines
Ensures consistent angles and repeatability
Suitable for complex structural parts

3. Key Bending Considerations

Bend Radius: Thicker plates require larger minimum bend radius to prevent cracking
Grain Direction: Bending perpendicular to rolling direction reduces cracking risk
Alloy Selection:
- 5052 → Excellent bendability
- 3003 → Very good formability
- 6061-T6 → Harder to bend, may require annealing

4. Post-Bending Treatment

Stress relief may be required for high-precision parts
Surface inspection ensures no cracking or surface deformation
Optional coating or anodizing for corrosion protection
