Difference Between Copper and Brass
Main difference
The main difference between copper and brass is that copper is a base metal while brass is an alloy of base metals copper and zinc.
copper vs. brass
Copper is a base metal that has a high electrical and thermal conductivity value, while brass is an alloy that has a low electrical and thermal conductivity value. Copper maintains its position in the periodic table. On the other hand, brass does not occupy a place in the periodic table.
Copper is in its naturally occurring state, while brass is not in its naturally occurring state; instead, it is made up of a mixture of base metals such as copper and zinc. Copper is natural, while brass is artificial. Copper is reddish orange. On the other hand, brass is yellow in color due to the presence of zinc content in it.
Copper is used to make musical instruments that have very smooth and mellow sounds. On the contrary, metal makes musical devices and instruments have a very high pitched sound. Copper is a soft base metal, which can be easily shaped. In contrast, brass is hard and more difficult to shape.
Copper has a malleable and ductile property due to its metallic nature. On the other hand, brass does not have properties of malleability or ductility. Copper comprises good forte, good tensile strength and corrosion abrasion resistance. On the contrary, brass has less strength and durability compared to copper.
Copper is mainly used in pipes, pipe fittings, and electrical wiring due to its high electrical conductivity. On the other hand, brass is mainly used in decorative items and musical instruments. Copper has a reddish-brown appearance in sunlight, while brass has a yellowish-brown hue.

What is copper?
Copper is a chemical element that has the symbol Cu and an atomic number of 29. It is a transition base metal that occupies the specific position in the periodic table. Copper is a soft, malleable, and ductile metal that has high thermal and electrical conductivity due to the presence of excess free electrons in the valence shell.
If the surface of pure copper is exposed to sunlight, a pinkish-orange hue appears. Copper is considered the best conductor of heat and electricity. Copper exists in the form that can be used directly without conversion to other forms.
Copper is heavily used as a building material, as well as a key part of various metal alloys, including sterling silver used in the manufacture of ornaments, cupro-nickel used in the manufacture of aquatic hardware and coins, and constantan used in pressure gauges. and thermocouples to measure temperature.
Copper also forms salts that impart blue and green colors to most minerals like azurite, malachite, and turquoise, etc. The use of copper in buildings is in roofing, where it oxidizes to form green verdigris. Copper also finds extensive use in decorative art in the form of metal, as well as compounds that exist in the form of pigments.
Copper compounds are used in the microbiostatic effect of bacteria. Many copper compounds can be used as fungicides and as food preservatives. Copper has an important role in the human dietary plan. It is used as a critical component of the respiratory enzyme complex called cytochrome c oxidase.
What is brass?
Brass is defined as an alloy or mixture of copper and zinc base metals, which includes the properties of both elements in their correct proportion. The percentage of elements like copper and brass can be changed according to their fluctuating electrical properties. Brass is recognized as a substitute alloy.
Brass has the property that the atoms of the two participants, i.e. copper and zinc, can replace each other within the same crystal lattice. Brass has properties similar to bronze, which is an alloy of copper and tin. Brass contains trace amounts of other elements, including arsenic, lead, phosphorus, aluminum, manganese, and silicon as well.
Brass is known for its bright golden appearance. Therefore, it is widely used for decorative purposes, i.e. drawer pulls and door knobs, etc. Brass has a low melting point, high durability, and high thermal and electrical conductivity. These properties allow its use in the formation of all kinds of utensils.
Brass finds wide use in locks, cruxes, rigging, bearings, valves, plumbing, plugs, household fittings, zippers, and plugs where low friction and low corrosion resistance are required. Brass is normally used in the formation of musical instruments that produce a very high pitched sound. Therefore, they are commonly used to make home speakers and doorbells.
Brass is also used as an alternative to copper in the production of jewelry, costume jewelry, and other costume jewelry today. For its application in jewelry, brass is mixed with zinc to increase its resistance to corrosion.
Key differences
- Copper is a transition base metal, while brass is an alloy.
- Copper is found in the d block of the periodic table. By contrast, brass is not found on a periodic table.
- The element copper contains copper atoms only in its pure form. On the other hand, brass contains copper and zinc atoms.
- Copper is reddish orange. In contrast, brass is yellow in color due to the presence of zinc content.
- When pure copper is placed under sunlight or a fluorescent light bulb, it appears reddish-brown in color. On the other hand, when brass is placed under sunlight, it gives it a yellow-brown hue.
- Copper has high thermal and electrical conductivity while brass has high durability and less thermal and electrical conductivity compared to copper.
- Copper is soft in nature. Therefore, it can be easily molded into the desired shape. In contrast, brass is hard in nature. Therefore, it cannot be easily molded into the desired shape.
- Copper is malleable and ductile, which is characteristic of the metal. On the other hand, brass does not show any properties of malleability and ductility.
- Musical instruments formed with copper produce a smooth, mellow sound. On the contrary, the musical apparatus formed by using brass produces a very high-pitched sound.
- Copper is mainly used in pipes, pipe fittings, and electrical wiring due to its high thermal conductivity. On the other hand, brass is mainly used in musical instruments and decorative items due to its golden appearance.
- Copper can be recycled after use and is soluble in water. In contrast, brass cannot be recycled and is insoluble in water.
- Copper is constituted in the formation of a complex of respiratory enzymes called cytochrome c oxidase, while brass is only related to non-living beings.
Final Thought
Copper is found in its naturally occurring state, and is a base metal, while brass is not found in its naturally occurring state, and is an alloy of copper and zinc.
