1.Simple description for copper sheet

• Oxygen free copper sheet is a type of copper that has had much of its oxygen content removed in an effort to improve its conductivity. The name actually is a misnomer, because trace amounts of oxygen are still found in this metal. Many audiophiles prefer this type of wire for stereo systems, claiming that it improves sound and volume quality. There are others within this community.

2.Test ways for our copper sheet 99.999%

• Product Testing  Using several kinds of Physical and Chemical Testing for better product quality to make comprehensive judgment,we will test products before deliverying to customers,physical analysis  Products`structure, Metallographic microstructure, chemical composition,and other sectors are analyzed according to material physical effect,chemical assay  professional team use chemical apparatus to test constant,trace,and ultratrace of our material.

3.Characteristics for oxygen-free copper sheet

• Low-temperature softening characteristic such as high-purity oxygen free copper;
• Superior elongation performance due to fine crystal grains formed by controllingmetallurgical structures;
• Both softness and long bending fatigue life time made possible by controlling metallurgical structure;
• High conductivity (> 101% IACS);
• Excellent welding performance equal to oxygen-free copper wire;
• High performance material produced by continuous casting and rolling.
