What is the difference between HDMI cable copper-clade steel and oxygen-free copper?


1. Copper cadded steel (CCA):Copper claded steel is a kind of composite material wrapped in copper on the steel core. The steel core provides strength and support, while copper provides conductivity.

Compared with pure copper, the conductivity of copper clad steel is low, so there may be a certain signal loss during signal transmission.

Due to the poor conductivity of copper-clad steel, it may affect the stability and quality of signal transmission, especially in long-distance transmission.

2. Oxy-free copper (OFC):Oxygen-free copper is a high-purity copper material, which does not contain oxygen impurities and has excellent electrical conductivity.

- Oxygen-free copper has high conductivity and conductivity, which can provide more stable and clear signal transmission.

Due to the excellent electrical conductivity of oxygen-free copper, it is usually used in places with high requirements for signal transmission quality, such as high-definition video, audio transmission, etc.

        To sum up, there are certain differences between copper clad steel and oxygen-free copper in signal transmission quality, conductivity and stability. Generally speaking, for applications that require high definition, stability and signal transmission quality, it is recommended to choose HDMI cables made of oxygen-free copper; for general applications or cost considerations, copper-caded HDMI cables can also meet the basic needs. When choosing, it can be weighed according to actual needs and budget.
