Aluminum 1 4 Sheet Weight Calculation

The weight calculation of an 1/4 aluminum plate with a certain thickness is closely related to the size of the aluminum plate.

Therefore, the weight calculation of 1 4 aluminum plate must first determine its size. Let’s take 4×8 1 4 aluminum sheet as an example to estimate the weight of 1 4 aluminum sheet 4×8:

1 4 aluminum sheet 4×8
Density Approximately 0.0975 lbs/cubic inch
Width 4 foot/1220 mm/48 inches
Length 10 foot/3048 mm/120 inches
Thickness 0.25 inch
6.35 mm
Volume 1152 cubic in
Wight 112.32 lbs

Therefore, the weight of 4×8 1/4 aluminum sheet is approximately 112.32 lbs or 50.947 kg.

Common Alloy:

1/4 5052 Aluminum Sheet:

The most common use of 1/4 inch thick 5052 aluminum sheet is for structural parts and enclosures in the aerospace industry. 5052 aluminum alloy has good corrosion resistance, strength and processability, and is often used to manufacture parts for aircraft, rockets and other aircraft, such as fuselage panels, wings and tails. 5052 aluminum plates of this thickness can also be used to manufacture shells, fuel tanks and body structures of ships and automobiles.

6061 1 4 Aluminum Sheet:

  • Aircraft structural parts: fuselage panels, wing panels, tail fins, etc.
  • Spacecraft components: satellite casings, brackets and connectors, etc.
  • Body panels and chassis components: doors, hoods, roofs, chassis supports, etc.
  • Suspension system and chassis components: suspension arms, shock absorber mounts, steering components, etc.

How to Bend 1 4 Aluminum Sheet ?

  1. Prepare equipment: 1 4  aluminum plate, table, clamps, ruler, mallet or hammer and bending brake or suitable bending tool.
  2. Mark the bend lines: Use a tape measure and pencil to mark the desired bend lines on the aluminum sheet. Make sure the lines are straight and accurate.
  3. Fix the plate: Place the 1 4 aluminum plate on the table and secure it with clamps. Make sure the panels are firmly in place to prevent movement.
  4. Create the curved edge: If you have a curved brake, line up the marked curve line with the curved edge of the brake. If you don’t have a bend stop, you can use a ruler as a guide to create the curved edge. Place a ruler along the marked curve line and apply firm pressure to create a crease or score line.
  5. Start the bending process: Using the bend brake, gradually apply pressure to bend the 1 4 aluminum plate along the marked line. If you are using a straight edge, place it below the score line and use a mallet or hammer to gently tap the board to bend it over the straight edge. Be careful not to hammer too hard or you may damage the board.
  6. Continue bending: For larger bends, move the ruler or bend stop along the marked line and repeat the bending process until you reach the desired angle. Take your time and make small adjustments as needed.

How to Cut 1 4 Aluminum Sheet ?

For aluminum plates with a thickness of 6.35mm, you can use a shearing machine or a high-speed circular saw to cut them. Specific steps are as follows:

Shearing machine operating steps:

Correctly set the cutting thickness and blade of the shearing machine. Place the 1/4 aluminum plate on the shearing machine according to the position of the cutting line, then use the clamping device to fix it on the workbench, and align the shearing blade with the starting point of the cutting line. Starting point and cutting step by step. Be careful to maintain a stable cutting speed and do not push the shear hard. After the cut is complete, check the quality and accuracy of the cut line. If necessary, use a file or sandpaper to smooth the edges.

High-speed circular saw operation steps:
Use a ruler and pencil to mark the cutting lines on the aluminum plate. Select a high-speed circular saw blade suitable for aluminum. Place the aluminum plate on a stable workbench and secure it with clamps. Place the high-speed circular saw to one side of the cutting line and start the cutter. Control the cutting speed based on experience and actual conditions. Push the circular saw forward along the cutting line, maintaining a steady cutting speed and pressure.
