Aluminum vs steel assault rifle series#
The composition of the 7075 aluminium alloy series makes it the one that offers the most strength, to the extent that it is comparable to that of many steels. What makes the 7075 alloy stand out from other aluminium alloys? This process guarantees achieving the peak strength of this alloy. The 7075-T6 aluminium is a 7075 aluminium alloy with a T6 temper, which is achieved by treating it with solution heat, homogenizing the 7075 cast at 450 ☌ for several hours, quenching, and then artificially aging it at 120 ☌ for 24 hours, which is around the time when it meets standard property requirements. It also contains 2.1 – 2.9% magnesium, 1.2 – 2%, and no more than 0.5% of silicon, titanium, chromium, iron, manganese, and other constituting metals.
The composition of the 7075 aluminium alloy consists of 87.1 – 91.4% aluminium, while the zinc is present in a concentration of 5 – 6%.
With zinc as the dominant alloying element, the 7075 aluminium alloy (also known as aircraft aluminium or aerospace aluminium) was the first alloy of high strength composed by Al-Zn-Mg-Cu that was able to successfully combine the perks of the inclusion of chromium to develop high stress-corrosion cracking resistance in sheet products. It also has low density and great machinability.
7075-T6 aluminium offers an excellent balance of properties that make it a reliable choice for a great variety of jobs.ħ075-T6 aluminium is an excellent alloy for highly stressed structural parts. Have you ever wondered what the 'perfect' choice of aluminium for your project is? Aluminium is the most widely used non-ferrous metal, and there are dozens of commercial options available, which greatly vary in properties based on their alloy composition and temper.
