Aluminum sheet metal fabrication process

The aluminum sheet metal fabrication process involves certain steps.

They include;

Cutting Aluminum Sheet Metal

Aluminum cutting removes material from metal stock, depending on the fabrication designs. Cuts can either be shear or non-shear.

A basic shear cuts through the material in a straight line on the flat metal stock using an upper blade and a lower blade just like a scissors does.

Another sort of shear cutting is punching or blanking, which involves punching designs out of a sheet of metal and discarding the remainder with a machine.

Laser cutting, which uses a focused beam of light, and plasma cutting, which uses hot compressed gases, are both examples of non-shear cutting.

It can also be done using waterjet cutting through concentrated streams of water-filled abrasives and machining with drill bits abrasives.

Riveting And Using Adhesive

Riveting joins sheets of metal with small metal pins or bolts by mechanical means. These joining processes do not need melting material together.

Adhesives join metal sheets with a bonding agent that can either act alone or reinforce another joining method.

Forming Aluminum Sheet Metal

This procedure reconfigures sheet metal without removing any material.

They include bending, stamping, or rolling forming the material into another shape.

Welding And Brazing Aluminum Sheet Metal

Welding And Brazing Aluminum Sheet Metal

Welding and brazing involve melting material.

Corrosion Resistance

Whereas malleability is very essential for manufacturing, aluminum’s greatest attribute is that it resists corrosion with no additional treatment after it is spun. Aluminum does not rust.

When using aluminum, there may be no paint or coating to wear or scratch off.

Steel or carbon steel inside the metals world commonly requires to be painted or treated after spinning.

This is done to protect it from rust and corrosion, specifically if that part of the steel may be at work in a wet, damp or abrasive environment.


Aluminum is a suitable metal because it has greater malleability and elasticity compared to steel.

Aluminum can go places and create shapes that steel cannot, frequently forming profound or more complicated spinnings.

Particularly for parts with deep and straight walls, aluminum is the desired material. Even though steel is a very tough and resilient metal.

It cannot be pushed to the same extreme dimensional limits as aluminum without cracking or ripping during the spinning procedure.


Steel is considered heavier than Aluminum. Steel acquires its weight from the high concentration of carbon.

Nonetheless, the added weight makes increases the durability of the steel. Steel is not likely to curve, warp, or distort underweight heat or force.

There exist lighter forms of steel that weigh the same as aluminum.
