Home Copper C101 Copper C101 Grade Summary: Copper C101 is an Oxygen Free Electronic Copper. This is a 99.99% pure copper having a 0.0005% oxygen content. This material has a minimum 101% IACS conductivity rating, and it is valued more for the chemical purity than electrical conductivity. it is finished to a final form and carefully regulated in a oxygen-free environment. The C101 Grade is one of the most expensive of the copper grades. Typical Applications: Used in engineering applications. Typical Chemical Analysis: * Other – 0.0/0.10 *Cu – 99.9/99.99 Typical Mechanical Properties** Tensile Strength (PSI): 43,500 Yield Point (PSI): 36,300 Rockwell Hardness: B40 * Chemical Analysis will vary on each heat number. ** All values are averaged values(based on H02 Temper)and are representative.
