What is 7000 series aluminum used for?

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).

Is aluminum good for casting?

Likewise, molds for the versatile process of permanent mold casting are often made from steel. Aluminum is a great choice for permanent mold casting, while ferrous alloys, like steel, are too hot in their molten state.

What does 7075 mean in aluminum?

7075 is a heat-treatable aluminum alloy with zinc as the primary alloying element. It has moderated formability when in the fully soft, annealed temper and can be heat-treated to strenght levels that are comparable to many steel alloys.

Is 7075 aluminum stronger than steel?

7075 is able to match most steel alloys in terms of strength. On the other hand, 7075 is one of the strongest aluminum alloys available. While 7075 is less workable than 6061, if your greatest consideration is strength, then 7075 is probably the better choice.

Which is stronger cast aluminum or aluminum?

Die engineering fees for new custom shapes are much less than when compared to castings. Extruded aluminum shapes are also produced with an excellent surface finish and are typically stronger in comparison. Castings have no such limit and are often used to produce very large items.

Which aluminum is best for casting?

A380 Aluminum Alloy The most popular alloy for aluminum die casting is A380. We use A380 because it has demonstrably the best combination of physical and mechanical properties for casting, including being lightweight, very strong at high temperatures and corrosion resistant.

Which is better 2000 series or 7000 series aluminum?

The 7000 series alloys have the highest strength in the aluminum alloys, but lower fatigue properties than 2000 series alloys. Thus, 2000 series alloys accounts for a large proportion of the aircraft components for their better fatigue properties than 7000 series alloys have not been elucidated yet.

Why are 7000 series alloys used in aircraft?

Then the 7000 series alloys will be used in most parts of an aircraft instead of 2000 series alloys became of their higher strength, leading to fuel cost saving as well as alleviation of the load against global warming through weight reduction. Andrew N. Rider, James J. Mazza, in Aircraft Sustainment and Repair, 2018

What kind of cracking occurs in 7000 series alloys?

From this fact and the already-known fact that hydrogen embrittlement based on intragranular cracking occurs in 7000 series alloys tested in MA, the larger fatigue crack growth rate of No.1 was presumed to be correlated with hydrogen embrittlement.

What’s the difference between 5000 and 6000 series alloys?

Most 5000 series alloys include manganese as well. 6000 series are alloyed with magnesium and silicon. They are easy to machine, are weldable, and can be precipitation hardened, but not to the high strengths that 2000 and 7000 can reach. 6061 alloy is one of the most commonly used general-purpose aluminium alloys.
