What is the difference between aluminum and extruded aluminum?

There are two different types of aluminum in the market: Hollow (or extruded) and Cast (which essentially means solid). Most hollow aluminum sets go through a process called extrusion. Support: Because extruded aluminum is hollow, it is more likely to dent or bend if it is thrown in the wind.

What is considered extruded aluminum?

Aluminum extrusion is a process by which aluminum alloy material is forced through a die with a specific cross-sectional profile. A powerful ram pushes the aluminum through the die and it emerges from the die opening. When it does, it comes out in the same shape as the die and is pulled out along a runout table.

What is extruded aluminum used for?

Aluminum extrusion transforms aluminum alloy into an extraordinary variety of products for consumer and industrial markets. Aluminum extrusions have many uses in the electronics, automotive, mass transit, bridge decking, telecommunications, solar/renewable energy industries, and more.

Does extruded aluminum rust?

Corrosion resistant: Aluminum extrusions offer excellent corrosion resistance. They do not rust, and the aluminum surface is protected by its own naturally occurring oxide file, a protection that can be enhanced by anodizing or other finishing processes.

Why is extruded aluminum so expensive?

The Die. The basic process for extruding aluminum is, outwardly, as simple to understand as the extrusion process used by a 3D-printer: heat material and force it through a die with the desired shape and size. More friction means more force, which means bigger presses, more wear on the dies, and generally higher costs.

What is the difference between cold finish and extruded aluminum?

Whereas an extrusion is typically performed at a high temperature when the aluminum is easier to form, cold finishing takes place at room temperature. When cold finishing occurs, it leads to extremely close outer diameter tolerances. Drawing also uses a die to reduce material diameter in aluminum bar production.

What is extruded aluminum 6063 Clean?

It is the most common alloy used for aluminum extrusions. Normally, 6063 Aluminum Extrusion scrap shall consist of clean aluminum profile extrusions including window, shop fittings, irrigation tubes and door frames. However, it must be free of screws, iron components, plastics, rubber or other foreign materials.

Is extruded aluminum stronger than cast aluminum?

Extruded aluminum products are generally stronger than cast parts. A casting may contain some porosity or other defects. 5. Aluminum casting is a more pricey fabrication process than extrusion due to the high initial costs.

Will aluminum rust in saltwater?

Does aluminum corrode in saltwater? Yes, it sure can. The less active, the more resistant it is to corrosion. When not in contact with anything else, most marine metals such as aluminum, bronze and stainless steel will corrode away at a reasonably slow rate.

How strong is extruded aluminum?

The result is a corrosion-resistant, lightweight material available in medium to high-strength forms. (Typical yield values are around 30,000 lbf/in².) An interesting point to note about aluminum is that strength actually increases at very low temperatures. This contrasts with steel, which becomes brittle.

What does cold finish mean aluminum?

Cold finishing for aluminum is more commonly referred to as cold drawing or cold rolling, which are forms of cold finishing aluminum by pulling material through what is known as a draw die or rollers. The term cold simply indicates forming the metal at room temperature as opposed to heating it first.
