The Difference Between Copper, Brass and Bronze


Hi and welcome to Metal Supermarkets, the Convenience Stores for Metal. I’m Jason Jackson, Operations and Development Manager. At Metal Supermarkets, we carry a selection of red metals, a term that refers to copper, brass and bronze. These three metals are similar
because they all derive from copper, but they are actually quite different. Today we’ll discuss those differences. Let’s start with copper. Along with having good strength and formability, copper is an excellent electrical and thermal conductor, second only to silver in electrical conductivity. It can be soldered, braised, polished and buffed to almost any desired texture and luster. Copper also has two other important attributes. It is corrosion-resistant and copper is found to kill more than 99.9% of bacteria within 2 hours of contact Copper is most commonly used in applications such as wire, electrical motors, and pots and pans Brass is a copper alloy that consists
mainly of copper and the main alloying element zinc. Brass can have a varying color, ranging from red to yellow and have different properties depending on the amount of zinc or other elements that are added. Generally if the zinc content ranges from 32% to 39% the brass will have increased hot working abilities, with limited cold working. If the brass contains over 39% zinc it will have a higher strength, but lower ductility. Brass is commonly used for decorative purposes due to its resemblance to gold. It is also used to make various musical instruments mainly due to its high workability and density. Bronze is a copper alloy with the main element being tin, and contains various other elements such as phosphorus, aluminum, manganese and much more. Bronze can be identified by its dull
gold color, but also has faint rings on its surface which is a result of being centrifugal casted Bronze is primarily used for sculptures, metals and in industrial applications such as bushings and bearings because of its low metal-on-metal friction. Bronze also has many nautical applications because of its excellent corrosion resistance. Hopefully this has given you a better
idea of the differences between the main red metals: copper, brass and bronze. Metal Supermarkets is the largest supplier of small quantity metals carrying over 8,000 types, shapes and grades of metal, including copper, brass and bronze, cut to size. Visit one of our Metal Supermarkets

  1. hi instructor would u pls to explain to me what abought the items exactly looks golden it self ? cuse usually hear in horn africa or ethiopia we have faced over for such items as a part of selected oldest goods like the old scale ballances also u can get it in that food crops grinding mashen as a break tools so I need u to advise me around those golden materials ur ex's

  2. Brass and bronze are both alloys of copper, but can you mix them together? I have always wondered if you could make a useful alloy out of brass and bronze, I wonder what would happen if you added a little Aluminium too? Is there a reason you never hear of a Bronze Brass alloy, or an alloy between them with a little Aluminium added.

  3. 🥇🖤 very interesting, I like your talent to explain complicated things.A question you indicate "copper is found to kill more than 99.9% of bacteria within 2 hours of contact" I knew that sodium hypochlorite killed 99.99% of life but I would like to know more about bacteria and copper …

  4. As a welder, I quickly learned that one does not heat bronze to bend it. I must be bent cold. When hot, it is as brittle as China. It shatters, crumbles.

  5. Thank you, Jason for that informative video, I hope Metal supermarkets thrives, though i have no use for metals at this point. I too wish you and your company luck in the future.

  6. If you think this gentleman has bad diction, go check out the beginning of any of Jay Leno's car videos. "Welcome to another episode of Jay Leno's garage" somehow becomes "WEK!umnudduhEposowduhJayLunozgraje…"

  7. The lines on the bronze bar are a result of the "continuous casting" process (aka: con-cast), NOT "centrifugal casting". Other than that, good video.

  8. "Brass is used mostly for decorative purposes".  Because it will not generate sparks, unlike steel, brass is heavily used for handling patroleum distillates (fittings and tools) and firefighting.

  9. Also, copper conducts heat better than any other metal, which makes it ideal for radiators and heat sinks.
    Of course, aluminum (which is the second best conductor of heat) is often used in place of copper because it is lighter and cheaper.

  10. Could someone tell me this; I have about 4200 of the pre-1959 (so-called 'wheatie') U.S. pennies, so how much would they be worth if I sold them to a metal recycler?  Would the copper in them be worth more than the face value as coinage?

  11. 2:24 Early Bronze was made from an alloy of Copper & Arsenic instead of Tin, and used a bit of Nickel to keep it from becoming too brittle

  12. I have always have called brass when it is eighty percent copper and twenty percent zinc. Any other combination is bronze.

  13. Thanks. I had to look up what ductility means, though i'm fluent in english there's always some words i won't recognise.😅

  14. Well, let’s test your metal,,,

    The secret of turning lead into gold is closely guarded.

    My copper chisels dull rather quickly, especially on red granite.

  16. Thanks for that nice educational information….you sending a- how to do- ways to get the right on point. Will be nice more of these info

  17. A chart would be nice to show the differences… THEY ALL SEEM THE SAME!! ALL COMES FROM COPPER… just added ZINC… sheesh
