The difference between pure copper and oxygen-free copper is as follows
1. Different purity
Pure copper does not contain oxygen or any deoxidizer residues, but 100% still contains a very small amount of oxygen and some impurities.
Oxygen-free copper is divided into No. 1 and No. 2 oxygen-free copper. The purity of No. 1 oxygen-free copper reaches 99.97%, the oxygen content is not more than 0.003%, and the total impurity content is not more than 0.03%; the purity of No. 2 oxygen-free copper reaches 99.95%, the oxygen content is not more than 0.003%, and the total impurity content is not more than 0.05%.
2. Different characteristics
Oxygen-free copper has high conductivity, and has good processing performance, welding performance, corrosion resistance and low temperature performance.
Pure copper has good electrical conductivity and thermal conductivity, and also has very good corrosion resistance, as well as very good solder joint.
MagEnergy copper jewelry is made of 99.9% copper, 99.9% copper is one of the names of pure copper. In fact, copper with a purity of 99.9% to 99.98% can be called pure copper. All pure copper will let the skin turn green when the skin touch the pure copper.
