Aluminum is ideal for use in extrusion processes as its malleable properties allow for the production of a diverse variety of shapes. These aluminum extrusion shapes can be customized to precise measurements and specifications for use in numerous applications.

Manufacture of Custom Shapes with Aluminum Extrusion

Unique shapes are created in the aluminum extrusion process through the use of custom-designed dies. As heated aluminum billets are rammed through the die in the extrusion press, the shape of the die functions as a mold, determining the uniform cross-sectional shape of the final product. The dies can be changed relatively easily and inexpensively, allowing for the production of multiple shapes without significant increases in production time or costs.

Dies can be created to meet the particular specifications required for a specific product. They can be solid, hollow, or semi-hollow depending on the desired shape. Once a die has been designed and built, it can be retained for re-use in future production as needed.

Benefits of Creating Shapes with Aluminum Extrusion

Although other processes can be used for manufacturing custom shape requirements, aluminum extrusion has specific advantages that make it an optimal choice for fabricating certain products.

Aluminum offers a multitude of design possibilities at economical pricing, facilitating its vast potential for applications. Aluminum extrusion is easy to work with when complex cross-sections or shapes that are designed to have non-uniform thickness are required. Aluminum extrusion can more easily produce single shape products, bypassing the need for welding or joining, thus reducing the manufacturing costs. It is also convenient to include groove and tongue, press, snap or sliding fit, self-tapping features in these extrusions, by specially designing the extruded shapes.

Applications of Aluminum Extruded Shapes

In addition to custom shapes, aluminum extrusion also offers standard shapes. These shapes are utilized in both exterior and interior applications, and the industries mentioned below. The building and construction industry uses aluminum extrusion shapes in architectural framing, door and window frames, shop fronts, and exterior and roofing cladding.

The transportation and automotive industries use extruded shapes extensively for railway c, automobiles, marine applications and other products. Many other commercial, consumer, and public are also common, including conveyors, vending machines and circuit boards. The potential uses for aluminum extrusion shapes continue to experience substantial growth, with an increase in the available options and the ability to design dies for specific shapes.


History of aluminium

Aluminium has gone on an incredibly interesting journey from precious metal to the material used
virtually in every sphere of human life in just one and a half centuries.

The ancient peoples made solid clay pots containing aluminum silicates; Greeks and Romans
used aluminum salts to prepare dyes in leather, in medicine to stop bleeding

Aluminium was named after alum (an aluminium-based salt), which is called 'alumen' in
Latin. This name was given by Humphry Davy, an English chemist, who, in 1808, discovered
that aluminium could be produced by electrolytic reduction from alumina (aluminium oxide),
but did not manage to prove the theory in practice

Jules Verne described an aluminium space rocket in his 1865 novel From the Earth to the

JIn 1886, independently of one another, Charles Martin Hall and Paul Heroult developed the
aluminum production process: later called the Hall-Heroult aluminum production process.
Today's large and modern aluminum production plants are also based on this process. In
1889 Karl Josef Bayer further perfected this process.
According to Woehler, metal potassium is used as a reducing agent. Technically, aluminum is
obtained by melting in a special electrolysis process (Bayer process). This process of producing aluminum requires a large amount of energy. The energy consumption in
aluminum production, in this case, is about 13 - 16 kWh / kg.

In 1903, the Wright brothers built an engine with an aluminium crankcase for the engine of
their first powered airplane.

Aluminium foil entered the market in 1910.

Alloy development began in 1911, improving physical properties and leading to new
industrial fields.

The first can of aluminum was produced in 1963, and today it is one of the most important
aluminum applications

1988: The Boeing-747-400, the best-selling model of the Boeing 747 family, is introduced. It
contains more than 66,000 kilograms of aluminium.

In the 1990s, Apple’s Steve Jobs took advantage of aluminium’s strength, weight, and beauty
to create laptops, iPads, and iPhones.
