Copper and brass grades: cross-reference of designation standards

Xometry Europe · Jun 3, 2020

There are a lot of different copper and brass grades as well as designation standards that are used depending on countries, company’s traditions and engineering practices. In order to simplify the communication process, we’ve gathered the most popular copper and brass grades and alloys and indicated how they cross reference with each other.
