Benefits of Stamped Aluminum Parts

Aluminum parts are popular due to the benefits below:

1. excellent surface finish

2. high strength-to-weight ratio

3. excellent thermal and electrical conductivity

4. low-temperature resistance

5. corrosion resistance. 

However, aluminum is more expensive than steel, and welding may require additional processes. Despite these, aluminum is desirable for most sheet metal stamping applications due to its mechanical, physical, and chemical properties.

Types of Aluminum Stamping Operations and Techniques

Metal stamping refers to techniques that transform aluminum sheet metal into any shape.

The primary methods used for stamping aluminum are:

Piercing Aluminum

Piercing aluminum involves punches and dies to create holes and notches in blank aluminum sheets.

Blanking Aluminum

A suitable metal stamping tool cuts a specific section from an aluminum sheet metal in blanking. Dies are commonly used for this and are ideal for removing the desired design from the workpiece. It is worth noting that blanking and punching aluminum are almost the same. However, the punching process removes the disliked part from the aluminum sheet.

Coining Aluminum

Coining is an aluminum bending technique using a metal sheet between a punch and a die. Aluminum can also be transformed into L, V, or U shapes using aluminum stamping.

Embossing Aluminum

In embossing, a tooling system presses a pattern onto an aluminum surface, creating either a raised or recessed design.

Aluminum Deep Drawing

Deep drawing forms depressions on aluminum. Tensional force pushes aluminum into the cavity. Fabricators minimize stretching.

Flanging Aluminum

You’ll need a metal stamping tool to add flange or flare to aluminum. You can do it once or multiple times. Another critical part is metal stamping operations.

Aluminum metal stamping offers four options: 

1. Progressive die stamping. Progressive die stamping uses a series of dies to conduct operations on the aluminum part.
2. Transfer die stamping. Transfer die stamping moves the aluminum part from one stamping station to another mechanically.
3. Four-slide stamping. Four-slide stamping is ideal for complex aluminum parts.
4. Fine blanking. Fine blanking produces stamped aluminum parts with high accuracy and smooth edges. 

   Each technique allows cutting, punching, blanking, or punching aluminum, depending on the desired final product.

Tips on Choosing Aluminum Alloy for Metal Stamping

When selecting aluminum stamping blanks, it is crucial to take into account the following significant factors:

– Strength

– Practical usage, which includes aluminum parts and their applications

– Level of corrosion resistance

– Ease of machining and welding

– Degree of formability

– Any additional treatments required, such as heat treatment

– Availability of aluminum material

– Potential surface finishing options, such as painting or powder coating
