A Rfew Questions About 7075 Aluminum Practicalmachinist

Oct 28, 2011 · Strength will be the same in all directions.

Dec 01, 2016 · The questions about blistering on 7075 alloy have come up frequently of late, so I thought it would be a good idea to revisit the answer. A few years ago I posed this question to Dr. Judy Runge, a metallurgist who also happens to be well grounded in anodizing.

Jan 20, 2015 · If you CNC machined it from a solid block of aluminum it would be better as the bends were not cold formed, but aluminum as a material is still a poor choice. But you're right in your original question that 7075 is likely better than the more common 6061, but aluminum is still crappy. Basically trying to swim upstream.

Apr 15, 2014 · My question regards cutting feeds and speeds in 6061 and 7075 aluminum. the majority of our machining is done on a Haas Mini Mill. During roughing i have an rpm of 2400 and a feerate of 11 (guessing its inches per minute).

Its relatively high cost limits its use to applications where cheaper alloys are not suitable. Aluminum 7075 alloy can be machined in the annealed condition. Oil lubricants are used for performing machining operations. 6061 Aluminum alloy is a precipitation-hardened aluminum alloy, containing magnesium and silicon as its major alloying elements.

In 1936, 7075 was the answer to questions like, “How do we improve fuel efficiency of our aircraft?” and “How do we lighten the aircraft while still keeping it strong enough to handle complex maneuvers?” Although 7075 doesn’t score as high in corrosion resistance as 6061, this alloy is extremely popular in the aerospace industry.

There are multiple levels of aluminum starting at 1100 which is the softest, un-heat treatable and does not machine. 7075 is the hardest and it is heat-treatable and machinable. This is why it makes it usable on BMX products since heat-treating makes it stronger and CNC machining is one of the most common ways of making a metal block into something for BMX like a stem.
