Brass is golden / yellow in colour, copper is red / orange. Brass will tarnish more rapidly with dilute acid, as the Zinc in the alloy reacts. Copper is a little more "gummy" if touched with a file, where as Brass gives clean hard shavings.
Studying the aspect, density, hardness or applying a method of analytical chemistry can be established the type of an alloy, sometimes the origin.
Also it is important to compare the object with another similar but very authentic objects, to evaluate the seller, etc.
Copper is easily scratched with a pocket knife. Brass is much harder and cannot be scratched easily. Also if the item has a powdery green patina then it is copper, Brass will not oxidize easily (Unless an electric current is applied in a moist enviroment). Brass is also usally lighter in color than copper. The tones of brass vary, but copper is fairly dark depending on its purity. Destinguishing bronz from copper can be a bit trickier. If you have a torch handy though it's easy when heated copper melts before brass or copper and emits a very distinct (and toxic) odor along with bright green light.
Brass is an alloy of copper and zinc. Copper is a metal itself.
The copper in brass makes brass germicidal. The malleability and acoustic properties of brass have made it the optimal metal for Musical Instruments.
Brass alloys are 90% recycled.
Aluminum makes brass stronger and more corrosion resistant.
Brass objects were at one time made completely by hand, later by machine. So, you need to familiarize yourself with how machine and hand made items differ from a manufacturing perspective. To do that, you need to visit antiques shops and museums and acquaint yourself with how designs have changed over the years and what age patination is. Also, the mix of metals that went into making brass changed over the years. Really early brass is paler in colour reflecting that.
Real brass: a magnet will not stick to real brass. If it is brass plated/coated it may stick to it.
There are many metals, brass is one of them.
Brass is not magnetic, brass is a yellow color
Brass is a metal it is an alloy
bronze
Brass can be a Alloy metal, and is also a Non-Ferrous Metal,I hope this helps :D
Brass and steel are examples of alloys, meaning they're made up of more than one metal.
I'm not 100% what brass knuckles were actually made for but i do know what people use them for..., its a metal thing that fits around your knuckles and you punch someone when you have it on.. it will hurt alot.
gold i think...
Brass makes Brass instruments for example, the Tuba, trumpet, euphonium,and trombone are ALL made of brass
With brass metal molded
is brass a precious metal
Brass is a metal alloy
Tubas are made of metal, frequently brass, hence the name "brasswind" (trumpets, trombones, tubas, etc). This is as opposed to "woodwind" (like flutes and clarinets)
Brass is an alloy (combination) of copper and zinc so is a manufactured metal NOT a base metal that can be mined from the ground.
Brass is an alloy of copper and zinc.
brass (metal) = le cuivre
Brass is a nonferrous metal. It has no iron in it.
Brass can be a Alloy metal, and is also a Non-Ferrous Metal,I hope this helps :D
each is a metal
Brass is a nonferrous metal. No iron is present in it.
No, brass is an alloy of copper and zinc.
