Cp 63 -

In the non-ferrous metal trade, CP stands for "Copper Cathode." The number 63 often refers to the atomic mass of copper (Cu-63 isotope) or, more practically, a specific grade within a manufacturer’s catalog. In the LME system, generally denotes a copper cathode that meets the following criteria:

It is worth noting that in the construction and DIY sectors, "CP 63" can also refer to a historical code for certain polyurethane sealants or gasket makers (such as a specific product from the Chemplex range). However, for the remainder of this article, we will focus on the industrial metal context unless otherwise specified. In the non-ferrous metal trade, CP stands for

While OFHC is purer, CP 63 offers the best balance of high conductivity and structural integrity for large-scale industrial use without the prohibitive cost of oxygen-free variants. While OFHC is purer, CP 63 offers the
