What is Phosphorus Deoxidized Copper

If you’re in the market for copper wiring or tubing, you may have encountered the term “phosphorus-deoxidized copper.” But what exactly does this mean? In short, phosphorus-deoxidized copper is a type of copper alloy that has been treated to improve its electrical and thermal conductivity. Let’s take a closer look at how this process works.

What is Phosphorus Deoxidation?

Phosphorus deoxidation is a process used to remove oxygen from molten metals, such as iron or steel. It can be used to reduce the amount of oxygen present in the metal and improve the quality of the final product. This process has been used for centuries by metallurgists and is an important part of the metal production industry. In order for molten iron or steel to be suitable for use in construction or manufacturing, it must have a certain amount of carbon and other elements present in it. However, when these metals are melted down in a furnace, oxygen can easily enter the mixture due to the high temperatures involved. As this oxygen combines with other elements, it can cause oxidation reactions that weaken the resulting material and make it unsuitable for use.

That’s where phosphorus deoxidation comes into play. By introducing a form of phosphorus into the molten metal, any oxygen molecules present will react with it instead of other elements, effectively removing them from the mix. This allows metallurgists to create metals with fewer impurities and greater strength than what could be achieved without using phosphorus deoxidation.

Process of Phosphorus Deoxidation

In order to create phosphorus-deoxidized copper, an impurity known as oxygen must first be removed from the existing material. This process is known as deoxidation, and it is accomplished by introducing chemicals like silicon and aluminum into the molten metal. These substances react with the oxygen in the molten metal, creating new compounds which are then removed from the mixture.

Once the oxygen has been eliminated from the mixture, phosphorus can be added back into the alloy. This creates a superior form of copper that is especially resistant to corrosion and oxidation. It also has excellent electrical and thermal conductivity characteristics, which make it ideal for a wide range of applications.

Uses of Phosphorus Deoxidized Copper

Phosphorus-deoxidized copper is used in a number of different industries due to its superior properties. It can be found in everything from electrical wiring and tubing to radiators and air conditioning systems. It is also commonly used for structural applications such as roofing panels, roof flashings, gutters, eaves troughs, downspouts, flashing tape, steel frames, and trusses. Finally, it can even be found in medical equipment such as MRI machines and X-ray machines where its high resistance to corrosion makes it ideal for use in these sensitive environments.

Benefits Of Using Phosphorus Deoxidation

The main benefit of using phosphorus deoxidation is that it allows metallurgists to produce stronger metals with fewer impurities than would otherwise be possible without this process taking place. In addition, because phosphorous reacts more quickly than other elements when exposed to high temperatures, this process can also help reduce energy costs associated with melting down metals. Finally, because phosphorus does not affect other elements in the mixture very much, there is less risk of creating harmful byproducts during this process compared to other forms of deoxidation.


Phosphorus-deoxidized copper offers many advantages over regular copper alloys due to its improved electrical and thermal conductivity properties. Its ability to resist oxidation makes it ideal for use in many different industries, such as electrical wiring and tubing manufacturing, as well as medical equipment manufacturing. Its strength also makes it useful for structural applications such as roofing panels and flashings. If you’re looking for a superior form of copper that will give you reliable results with minimal maintenance required, phosphorus-deoxidized copper may be just what you need!
