Aluminum Bronzes 02 26 2023

 So I read that copper can cause aluminum to oxidize (sometimes thought of as rust no matter what type of metal it is.)

Which brings me to the question, "If one causes the other to rust can or are the two ever mixed to form an alloy?  And if so what are the properties of such alloy primarily in terms of oxidation resistance and strength, and hardness."

I haven't done a lot of research on this to answer all the questions.

However copper aluminum alloys are called Aluminum Bronzes.

And some of them have a high hardness the equivalent of medium carbon steel.

Some more questions I will read about are, where are they used in industry?

Probably where light weight is needed as well as hardness or perhaps thought of as the resistance to deformation at high rates of speed? 

Do Aluminum Bronzes represent a cost savings as well as superior properties in some applications?

Ps.

More probing of search results.

" Does aluminum bronze tarnish?

Aluminum bronze is tarnish-resistant and resists corrosion from atmospheric conditions, high temperatures, low temperatures, and harsh chemical environments."

 

It can turn a light patina of green as well as other colors!

 

"It is known for high as-cast strength and favorable anti-wear properties." 

It is non magnetic and non sparking.

Anyhow, very interesting.
