Would a composite of say copper and nickle be considered a bronze?
From what I understand copper is the basic component of bronze

Just picking brains

Thanks

    a.
    any of various alloys consisting essentially of copper and tin, the tin content not exceeding 11 percent.
    b.
    any of various other alloys having a large copper content.

    Bronze is copper alloyed with tin while brass is copper alloyed with zinc.

    It's one for the metallurgists I imagine.

    nickels are 75% copper and 25% nickel.

    "any of various other alloys having a large copper content."

    75% seems large, but a nickel doesn't seem like bronze.

    From what I see online, I'm seeing just CuNi alloys as cupro-nickel alloys apart from brass and bronze.

    I still defer to the metallurgists.

    There is a bronze that has both tin and zinc in it, it's called Roman Bronze.

    Copper and Nickel is cupro-nickel as long as it also has some manganese or iron in it as well I believe.


    Good for you.

    Off to learn about metalurgy and its terminology. Thanks.

    Good question about metallurgy. Composition has always fascinated me like math does. Even more so since I started buying scrap gold and silver and getting this "RING" in my head, especially as purity is concerned. I buy a ring that says 14K. That means it is composed of .585 GOLD. If it's yellow I'm assuming it's mixed with copper. If it's white, I assume it's mixed with nickel. Now I don't know what else they (metallurgists, melters, processors) mix with it, but when the refinery (assayer) buys it from me at 98% and tells me it is only .483 pure, I have to adjust my "buy numbers", because the reality is someone is cheating. lying, or stealing... at one end or the other. It's not for me to know, ... its just for me to adapt.

    Bronze is considered "sculpting material" that makes more money than other precious metals. It makes shell casings, too... but we call it brass. Like we call jewelry scrap.

    Just releasing brain waves. Hope you like picking.
