Advantages And Disadvantages Of Aluminum Extrudates

The use of aluminum for metal extrusions has increased greatly in the recent years. Aluminum has a long list of desirable properties that allow it to be used in several applications, but it too has a few shortcomings. Below are a few advantages and disadvantages of the metal.

High strength to weight ratio

Compared to other metals like stainless steel aluminum is extremely lightweight and it is relatively strong. Usually it is alloyed with another metal to improve its strength.

Economical

Extruded aluminum profile are extremely cost effective due to a number of reasons.For one, it is very light by nature, so you can ship a greater amount of the metal compared to other metals. Also since it has a high strength to weight ratio you can make a strong product with less raw materials by creating thinner walls. This metal is also highly resistant to corrosion, thus there will almost be no maintenance cost.

Even after its useful lifespan any aluminum extruded profile has a high scrap value. Unlike most other materials aluminum does not significantly change its properties during recycling. Recycling is environmental friendly too. Visit this page http://www.hxalu.com/products/window-door-profiles for further information regarding aluminum profile for sliding door.

Non-combustible

This metal does not melt very easily. Thus it will not emit toxic gases when it is heated.

Seamless extrudes

Aluminum extrudates are usually produced using one block. Thus you not find any seams on the extrudates, thus it improves the strength of the product. So the structure will hold shape overtime.

Non-magnetic and reflective

The inability of a metal to be magnetised can prove to be useful in applications where the sample or operating conditions are heavily affected by and external magnetic field.

The reflective nature of the metal gives the user an opportunity to polish the final product till it shines.

Good conductor

Aluminum can act as an extremely good heat and electrical conductor. There are several applications that utilise these properties. Its heat conducting properties are useful in applications like cooling tubes. The electricity conducting properties of aluminum become useful in applications like mainframe computers.

Limited colour

Colouring of aluminum extrudes are done primarily through four methods. These are namely, dyeing, electrolytic painting, integral colouring and interference colouring. The main problem with these processes is that the colours you are able to use are limited.

Limited shapes

Extrudates are produced using a die that will give uniform thickness products. Preparing a die is an expensive procedure, thus it will not be discarded once it is made. This results in limiting the designs of products that can be made.

When you go through the list you can see that the advantages of aluminum have exceeded the disadvantages by far. Thus it is no wonder that the use of aluminum has become so popular.
