What is H62 brass?
H62 copper alloy, characterized by an average copper content of 62%, is classified as a standard brass. It is a unique composition that integrates other elements into the traditional brass matrix, resulting in what is often referred to as special brass. The amalgamation of copper and zinc provides H62 brass with excellent electrical conductivity and ductility, while the presence of zinc contributes to its durability and structural integrity.
