Bronze vs Copper

What is Bronze?

Bronze is an alloy that is made up of a variety of different metals, including copper, tin, and zinc. It has a wide range of uses due to its strength and durability.

Some of the most common bronze alloys are used in:

  • Bearings
  • Gears
  • Pump impellers
  • Valves
  • Bushings

Because bronze is so strong, it is often used in applications where there is a lot of friction or wear and tear. For example, early steam engines used bronze pistons because they could withstand high temperatures and pressures better than other materials. Today, you can still find bronze being used in similar applications, such as in hydraulic systems.

How is Bronze Made?

Bronze is made by combining copper and tin, which are both found in nature. The exact proportions of these metals can vary, but the most common ratio is 90% copper to 10% tin.

Other metals, such as zinc, aluminum, or manganese, can also be added to create different types of bronze alloys. For example, adding zinc creates a brass-like alloy that is used in musical instruments and plumbing fixtures.

Once the desired mixture of metals is achieved, they are melted down and combined in a furnace. The molten metal is then poured into molds, where it will cool and solidify.

The molds come in various shapes and sizes, depending on what the bronze will be used for. For example, bearings are typically made with a cylindrical shape, while gears are usually cut into a more complex shape.

What are the Properties of Bronze?

Bronze is known for its strength and durability. It is also corrosion resistant and has a low friction coefficient, making it ideal for high-wear applications.

In addition to these properties, bronze also has excellent thermal and electrical conductivity. This makes it good for electrical applications, such as wiring or switchgear.

Another advantage of bronze is that it can be recycled without losing its properties. This makes it a sustainable option for many different projects.

Disadvantages of Bronze

Although bronze has many positive attributes, there are a few drawbacks to using this material.

First, bronze is usually an expensive option when compared to other metals. This is due to the high cost of copper and tin.

Second, bronze is not as strong as steel. This means that it is not suitable for applications where high levels of force are required, such as in construction.

Finally, bronze can be susceptible to corrosion if it is not properly cared for. This can cause the metal to weaken and break over time.

How to Care for Bronze

Proper care and maintenance are essential to keep bronze in good condition. The first step is to protect the metal from moisture and humidity, as these can cause it to corrode.

If the metal does become wet, it is important to dry it off as soon as possible.

In addition, bronze should be cleaned regularly to remove any dirt or debris that could cause corrosion. A mild soap and water solution can be used for this purpose.

Finally, it is important to regularly apply a coating of wax or oil to the metal. This will help to create a barrier against moisture and other corrosive elements.

  • Alpha brasses: These are alloys that contain between 30-45% Zinc and have good ductility (malleability). They are commonly used in architecture and engineering for their aesthetic appeal.
  • Manganese bronze: This type of bronze contains around 5-12% Manganese, which gives it excellent strength and toughness. It is often used in maritime applications, such as propeller shafts and hull plating.
  • Aluminum bronze: As the name suggests, this type of bronze contains a high percentage of Aluminum (around 9-12%), which gives it excellent corrosion resistance properties. It is often used in marine environments and chemical plants.
  • Leaded bronze: This type of bronze contains around 0.5-2% lead, which makes it easier to machine and gives it good wear resistance properties. It is often used in bearings and bushings.
  • Tin bronze: This is the most common type of bronze, containing around 60-90% copper and 8-40% tin. It has a wide range of applications due to its good strength, ductility, and corrosion resistance properties.
  • Nickel bronze: This type of bronze contains around 10-30% nickel, which gives it excellent corrosion resistance, strength, and toughness. It is often used in marine environments, chemical plants, and other harsh environments.

Bronze is a strong, durable, and corrosion-resistant metal with a wide range of uses. It is made by combining copper and tin and can also contain other metals such as zinc or aluminum.

What is Copper?

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware, and coins, and constantan used in strain gauges and thermocouples for temperature measurement.

Copper is one of the few metals that can occur in nature in its native form, not needing to be extracted from an ore. This led to very early human use, from c. 8000 BC. Copper used in buildings, usually for roofing, oxidizes to form a green verdigris ( patina).

4 Main Types of Copper

  1. Chalcopyrite: Chalcopyrite is the most important ore of copper. It has a chemical composition of CuFeS2 and is the most abundant sulfide mineral found in hydrothermal veins and metamorphic rocks. About 80% of the world’s reserves are in chalcopyrite.
  2. Cuprite: Cuprite, or red copper ore, has a commercial value because it contains about 79% copper oxide. Cuprite occurs as a secondary mineral in oxidized zones of copper deposits.
  3. Malachite: Malachite is a green carbonate mineral with the chemical composition Cu2CO3(OH)2. Malachite is often found in the weathered zone of copper deposits and is occasionally the gangue mineral in silver mines.
  4. Azurite: Azurite is a deep blue carbonate mineral with the chemical composition Cu3(CO3)2(OH)2. Azurite is produced by the partial oxidation of copper sulfides and is often found in association with malachite.
