What is 7000 series aluminium?
7000 series are alloyed with zinc, and can be precipitation hardened to the highest strengths of any aluminium alloy (ultimate tensile strength up to 700 MPa for the 7068 alloy). Most 7000 series alloys include magnesium and copper as well. Aluminium-lithium alloys are an example.
What is 7000 series aluminum used for?
Aluminum alloys Aluminum alloy 6061 and alloys of the 7000 series are most commonly used in the production of bicycle frames (Easton Sports). The 6061 aluminum alloy (Al-Mg-Si) contains 0.8–1.2 Mg, 0.4–0.8Si and 0.15–0.4Cu (wt%). It shows good corrosion resistance, strength and weldability (Kearney, 1990).
What is T6 condition for aluminum?
The T6 temper designation means that the aluminum alloy has been given a solution heat treatment followed by quenching, cooling, and aging. Artificially aging allows the material to achieve the desired precipitation hardening.
How strong is 7000 series aluminum?
72,000 pounds per square inch
The strongest aluminum alloys – 7000-series alloys – can reach strengths in excess of 72,000 pounds per square inch. A 1.2-inch aluminum wire made from this alloy could suspend a fully-loaded tractor-trailer in the air.
What is the difference between 6000 and 7000 series aluminum?
The 7000 series alloys which contain Zinc, and even Copper, have the highest strength values. 6000 series has a higher elongation at break; that is, it has a greater deformation before it breaks, while 7000 series has a much higher tensile strength. Both alloys (6000 and 7000) are of very high quality.
What aluminium alloy is used for aircraft?
7075 Al alloy
Among these, the 7075 Al alloy is most preferred by the aircraft industry. The composition of this specific Al alloy is 5.1–6.1% zinc, 2.1–2.9% magnesium, 1.2–2.0% copper and less than 0.5% of silicon, iron, manganese, titanium, chromium and other trace metals.
How strong is aircraft grade aluminum?
A high-grade alloy with excellent fatigue resistance, 2024 is used primarily in sheet forms such as for the fuselage and wings due to its high tensile strength of roughly 470MPa. Of the non-heat treatable grades of alloy, 5052 provides the highest strength and is highly ductile, so it can be formed into various shapes.
What grade of aluminium is used in aircraft?
Grade 6061-T6 is often used to make landing mats for aircraft, truck bodies, and frames as well as structural components. It can be fabricated using the most common techniques which is an excellent property.
What kind of material is 7000 series aluminum?
In fact, these 7000 series alloys belong to the super hard aluminum. And they are the perfect material for the aerospace field. In addition, the 7000 series aluminum is better material of vehicles, sheet metal parts, molds, precision instruments and other high-performance requirements of the conditions.
Which is the highest strength aluminum 7075 or T6?
7075 is part of the 7000 Series of aluminum alloys, which is considered the highest strength series of aluminum alloys for aircraft applications. 7075 contains zinc as the primary alloy addition and possesses excellent fatigue properties. However, in the T6 temper its fracture toughness can be inferior to other alloy choices.
Which is better 7075 T6 or 2000 T6?
While, more susceptible to embrittlement than many other aluminum alloys, it has far better corrosion resistance than the 2000 alloys. It is one of the most commonly used aluminum alloys for highly stressed structural applications such as with aircraft parts. 7075-T6 aluminum is 7075 aluminum in the T6 temper.
Which is better T6 temper or 2000 alloy?
However, in the T6 temper its fracture toughness can be inferior to other alloy choices. It has excellent mechanical properties, and exhibits good ductility, high strength, toughness and good fatigue resistance. While, more susceptible to embrittlement than many other aluminum alloys, it has far better corrosion resistance than the 2000 alloys.
