FAQs
Copper was one of the first metals that was ever used by humans, and since its discovery in approximately 8000 B.C. we have found many innovative and useful ways to utilise copper metal.
Copper’s main properties and qualities include great ductility, excellent conductor of electricity and heat; it is also a malleable metal. Due to these characteristics, copper is often used in electrical components such as motors, wiring, machinery heat exchangers and electronic connecters.
Copper is also one of the primary metals used to make cooking utensils and equipment, but the copper that we probably have the most daily contact with – coins.
The density of copper in its purest form is 8.92 gm/cm3.
An easy way to determine if your copper is pure via density is to use the following method:
If your result isn’t the same as above, this might mean your copper is not pure or that your measurements are not accurate.
Copper is an incredibly versatile metal with a broad set of properties that make it ideal for numerous applications. Key benefits of copper include:
Sulphur copper is the addition of sulphur to a standard copper. Pure copper has excellent thermal and electrical conductivity, as well as great ductility and corrosion resistance, but the metal has poor machinability.
When sulphur is introduced to copper, the workability of the metal significantly increases, without having to compromise on the favoured and beneficial aforementioned properties. Pure copper has a machinability rating of 20%, in contrast to sulphur copper that has an 80% machinability rating.
Sulphur copper has machining speeds that are four times faster than pure copper and since the compound produces a much softer metal, it is less detrimental on tooling and machining components.
Sulphur copper is used in applications that require good corrosion resistance, excellent thermal and electrical conductivity, but also applications that demand easy forming and extensive machining that pure copper is unable to handle.
Some examples of these applications include:

Copper Chromium Zirconium is a high copper alloy in which chromium and zirconium have been later introduced. Pure copper has outstanding electrical and thermal conductivity properties, but the chromium and zirconium are added to improve a number of mechanical properties and their performance.
Copper Chromium Zirconium is significantly stronger than soft pure copper and its key characteristics frequently see the compound being used in welding equipment, rotating machinery, circuit breakers, switchgear components and electrical conductors, to name a few.
Copper is a versatile method with a wide-ranging portfolio of properties that makes it the ideal metal to use in a variety of applications including in copper bar form. Some of the most useful properties of copper bar are:
Copper was one of the first metals that was ever used by humans, and since its discovery in approximately 8000 B.C. has been used in many innovative and useful ways.
Copper’s main properties and qualities include great ductility, excellent conductor of electricity and heat making it ideal for use as copper bar or rod. It is also a malleable metal making it suitable for all sorts of purposes. Due to its conductive characteristics, copper is often used in electrical components with copper rod often used in architectural metalwork, radiators and more.
Copper bar is also one of the primary materials used to make cooking utensils and equipment.
The density of copper in its purest form is 8.92 gm/cm3.
An easy way to determine if your copper bar is pure via density is to use the following method:
Measure the weight of your copper bar
Measure the dimensions of your copper rod to discover its volume (volume = L x W x H)
Divide the weight of your copper bar by the volume
Compare your results with the density of pure copper which is 8.92 gm/cm3
If your result isn’t the same as above, this might mean your copper bar is not pure or that your measurements are not accurate.
A copper busbar is primarily used as a conductor that collects electricity from the power source and distributes it to various circuits. Copper is an excellent conductor making it ideal for many other electrical applications including:
Copper busbars offer several key advantages, including:
Copper round bars are commonly used in electrical, automotive and plumbing applications due to their excellent conductivity and corrosion resistance. They are also utilised in heat exchangers, motors, and construction projects, as well as in the production of fasteners, connectors, and architectural elements.
Copper bars come in various shapes to suit different applications, including:
Copper rods provide high electrical conductivity, making them ideal for electrical applications. They are corrosion-resistant and durable, which makes them suitable for harsh environments. Copper rods also offer excellent thermal properties, and they are easy to form and fabricate, making them a versatile option.
Copper rods are widely used in electrical wiring, earthing systems, and power generation equipment. They are also utilised in machined parts for electrical connectors, motor parts, and transformers due to their excellent conductivity and malleability.
A copper rod is a cylindrical piece which can be as thin as wire and used for electrical wiring, grounding, and as raw material for electrical components. In contrast, a copper bar is thicker and comes in multiple shapes, such as flat, round, or square, and is used for busbars, switchgears, and other electrical and structural applications. The rod is typically used in finer electrical work, while bars are often for larger power distribution systems.
Phosphor bronze grade PB1 is a cast bronze alloy with high tin content and small amounts of phosphorus and is known by the designation CC481K in European standards.
It has excellent corrosion resistance, particularly in marine environments, as well as good strength and wear resistance. PB1 is commonly used in applications like marine components, bearings, bushings, and gears, where durability and resistance to wear are critical.
PB102, also known by its European designation CW451K is a wrought phosphor bronze alloy, mostly composed of copper with about 5% tin and a small amount of phosphorus.
It is known for its excellent strength, corrosion resistance, and good electrical conductivity. PB102 is commonly used in applications requiring high wear resistance and fatigue strength
PB102 (CW451K) is widely used in applications requiring excellent wear resistance and strength, such as:
