Although aluminum is already a versatile metal with various lightweight, anti-corrosive properties, its strength and suitability for various manufacturing projects can be further enhanced by combining it with other metals to produce a range of alloys. These are largely separated into two categories of either heat treatable and non-heat treatable alloys. The former includes metals such as zinc, copper, and silicon which all respond well to the aluminum extrusion process. During this procedure, the combined aluminum alloy is subjected to extreme temperatures to cure or age the metal. Non-heat treatable alloys include magnesium and through a process of strain-hardening or cold-working provides the aluminum alloy with additional strength.
What is an Aluminum Alloy
If we explain more about aluminum alloy so we can say an aluminum alloy is a chemical formation where several other elements are added to 100 % pure aluminum in order to boost its properties, primarily to increase its strength and these other elements include iron, silicon, copper, magnesium, manganese, and zinc at levels that combined will probably make up as much as 15 percent of the alloy by weight. Alloys are allocated a four-digit number, in which the 1st number specifies a general class, or series, characterized by its main alloying elements.
Aluminum Alloys and Uses
The aluminum alloys are graded into different categories numbered from one to seven which highlight their suitability for various manufacturing projects. Let us talk about these.
One - this alloy consists of around 99% aluminum and has one of the best electrical conductivity rates for use in the electronics industry and this series is often regarded as having the most resilience to the damaging influence of other substances such as acid. Consequently, it is frequently used for chemical storage.
Two - contains additions of up to 6.8% copper that produces an aluminum with increased strength. It also performs well when subjected to extremes of temperature making it ideal for use within the aviation and aerospace industries.
Three - this aluminum alloy includes manganese in various proportions of up to 1.8%. The resulting metal has only a moderate strength but it performs well in high temperatures. Its principal use is for vehicle heat exchangers and for domestic cookware.
Four - includes silicon which increases the malleable properties of the aluminum alloy.
Five - incorporates up to 6.2% magnesium. As a versatile aluminum alloy with excellent strength, it is frequently used in the construction industry for buildings and bridges, for use in the automotive industry and for building boats and ships.
Six - contains small additions of the silicon and magnesium. This malleable form of aluminum alloy is popular for use in the extrusion process for a variety of manufacturing applications.
Seven - up to 12% of zinc ensures that this aluminum alloy has superior strength. Common uses include the manufacture of sports equipment and for many uses within the aviation industry.
