Is oxygen free copper speaker wire better?

According to tests, oxygen-free copper also runs cooler than other conductors. It’s more resistant to shorts, more durable and long-lasting, and is far less likely to corrode, due to the reduced oxygen content—at least, that’s the common wisdom.

What is copper oxygen free wire?

Oxygen free copper is a type of copper that has been refined in an electrically charged solution of copper sulfate and sulfuric acid. Some manufacturers also state that oxygen free copper wiring provides better clarity of sound, and lasts longer than other, less pure, copper wires.

What is oxygen free copper used for?

Oxygen-free copper is used for industrial applications, such as for the windings in large electrical generators where the wire is constantly exposed to high temperatures and vibration, as well as for audio and video cabling, where the increased conductivity is believed to improve low-frequency transmission.

Is bare copper oxygen free?

This speaker wire features two conductors made of high purity (greater than 99.95% pure), oxygen-free bare copper. Pure Bare Copper is a superior conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire. CCA is only about 68% as conductive as pure bare copper.

How much better is OFC vs CCA?

Another PRO of using OFC is that it carries much less heat than CCA. While testing a 20 ft strand of 1/0, using the same current we found that CCA holds 30% more heat than OFC.

Is pure copper speaker wire better?

Copper is a good wire material due to its high conductivity and agreeable mechanical properties. Aluminium is cheaper and lighter but difficult to connect electrically.

Is copper wire Good for speakers?

Copper : Copper is the most commonly used material for speaker wire. Its cost is reasonable and it has a good level of conductivity, i.e. it provides a low level of resistance in the wire. It is also considerably more expensive than copper. This means that a thicker copper wire will actually still be cheaper to buy.

Does OFC cable make a difference?

There’s a big difference between copper-clad aluminum (CCA) and oxygen-free copper (OFC) wiring. Copper wiring on the other hand produces less heat and reduces the overall strain on your car’s system. Another benefit of OFC wiring includes less oxidation. Oxidation reduces current-carrying efficiency of the wire.

How do you make oxygen free copper?

Oxygen free copper is produced by melting and casting the copper cathodes in reducing atmosphere. The highest purity (A-grade) copper cathodes are used as the raw material. The reduction of oxygen from the melt can be done either by carbon or vacuum. Both methods result in a low oxygen content.

Is OFC pure copper?

This is a 99.99% pure copper with 0.0005% oxygen content. It achieves a minimum 101% IACS conductivity rating. This copper is finished to a final form in a carefully regulated, oxygen-free environment.
