From Brave AI:
Red brass Red brass, also known as C23000 brass, is an alloy that typically contains 85% copper and 15% zinc. It is highly valued for its durability, corrosion resistance, and ease of casting. This alloy is widely used in various applications due to its properties:
Plumbing: Red brass is commonly used in plumbing fixtures, pipes, and fittings because of its excellent resistance to dezincification and season cracking. It is also specified for underground service lines due to its corrosion resistance to all types of potable waters. Jewelry: The distinctive reddish hue and malleability of red brass make it a popular choice for jewelry, especially for creating intricate designs. Musical Instruments: In the context of musical instruments, particularly trombones, red brass is used for the bell to influence the sound quality. Users report that a rose brass bell (which is another term for red brass in this context) can produce a more mellow sound compared to yellow brass, which tends to produce a brighter tone. Recycling: Red brass scrap, also known as gunmetal, is highly sought after in the recycling industry due to its high copper content, which exceeds 80%, making it more valuable than yellow brass. Other Applications: Red brass is also used in fire hose couplings, zippers, condenser and heat exchanger tubes, and as a material in modern architecture due to its rich inherent color. Red brass is distinguished from yellow brass by its higher copper content and lower zinc content, which contributes to its superior corrosion resistance and strength.

All that glitters is not Orichalcum, PinGGG!................
I was hoping for Mithril.
I found a huge deposit of unobtanium on my property last week.
Interesting stuff. I knew that brass was an alloy of copper and zinc, bit that’s all.
Whoa! I think I’ve may have a couple buckets of Orichalcum under the loading bench in my garage... Cool!

Red brass also contains lead ….
California brass does not. It was a new metal invented by the idiots in the California legislature because lead is evil.
Now the brass sold here is brittle and hated by people who work with it for its ridiculous cost and substandard durability.
unfortunately not rare, is the bolognium deposit in DC.

“musical instruments...particularly trombones, red brass is used for the bell to influence the sound quality....a rose brass bell (aka red brass) can produce a more mellow sound compared to yellow brass, which tends to produce a brighter tone.”
That’s amazing. I had no idea. It must have to do with natural frequency changes in the bell section between red and yellow brass.
Thank you for post. Interesting subject.
I was in the wholesale hardware distribution business for 40 years. Observed a lot of strange things related to brass in plumbing.
40 years ago, brass valves were the norm, not so much today. I have seen brass harden and become brittle after years of use in very hot water (mixing valves). I suspect the zinc content is leached out and the brass is even more red than when the faucet was manufactured. I have seen mixing valves where the Hot water side was noticeably more red than the cold water side.
Plumbing was very simple 50 years ago, faucets lasted longer and could be fixed easily. Today there are some great valves with very little brass in them, but there are so many different variations in how they work, it is hard to repair one.

OK, I have question for the physics and electrical geniuses here... Since Zinc and Copper are used as Cathodes and Anodes what would happen if they were both the same at 30% alloy of both? Would both positive and negative poles in a battery with electrolyte produce 1.2 volts as it should in a cell? Would it cancel it’s self or would it open the door to AC batteries since it has properties of both?
I ask this because one time I did a study on just boulders around where I lived at the time. While they all had both DC and AC output, they had selective polarity with no difference to orientation to the magnetic field, and some had more DC than AC and others had more AC than DC.
So I do know that a “mix” is super critical to what you get out of alloys in an electrolyte. Would a same mix of the two on both Cathodes and Anodes still work and produce? Could it set up a cycle and produce AC??? Or would it just cancel each other because of like kind element alloys?
Now before you answer please think outside the box and ditch everything you think you already know and have been taught... Use your own gut knowledge about possibilities with this. Because this is what Tesla and Edison did which made them unique...
But I am curious as hell...
