OFHC Copper Plate

 

Oxygen-free copper also referred to as OFC, Cu-OF, Cu-OFE, and oxygen-free, high-conductivity copper (OFHC) is formed by melting copper and combining it with carbon and carbonaceous gases. The electrolytic copper refining process removes most of the oxygen contained within, resulting in a compound that consists of 99.95–99.99% copper with less than or equal to 0.0005% oxygen.

 

The high purity levels of oxygen-free copper enhance the properties typical of standard copper material, such as thermal and electrical conductivity, ductility, impact strength, and machinability. Due to these advantageous properties, the material finds use in a variety of industrial applications.

 

 

-Composition: OFHC copper has a high purity level, typically 99.95% copper or higher, with low levels of oxygen and other impurities.

 

-Properties: OFHC copper is known for its excellent thermal and electrical conductivity. It is often used in applications where high thermal conductivity is crucial, such as in the production of heat exchangers and electronic components.

 

Alloy Grade	Material Characteristics	Application
OFHC Copper C11000 Cu≥99.90	It has good electrical conductivity, heat conduction, corrosion resistance and processing properties. It can be welded and brazed.	Widely used for electric, heat conduction, corrosion resistance equipment. Such as: wire, cable, conductive screw, blasting
	The impurities and trace amount of oxygen only have very few effect on electrical and thermal conductivity. But the trace oxygen is easy to cause "hydrogen disease", so it can't be processed and used in high temperature (such as > 370℃).	detonator, chemical evaporator, storage device and a variety of pipes etc.
