Tin Plated Copper & Brass Strips | Business | Sumitomo ...

2015-2-1 · Copper and brass strips are tin plated and reflow-processed to improve their properties such as solderability, electric connectivity, and corrosion resistivity. These are highly reliable materials that were reflow processed after being tin-plated to prevent the generation of tin whiskers, which used to be a weakness of tin plating.

Metal Recycling - Aurubis

2021-11-19 · Europe has a high copper demand but limited natural resources. Metal recycling opens up the metal reserves found in products and therefore makes a considerable contribution to the supply of copper and other metals. Copper recycling fulfills the criteria for sustainable development and is the foundation of modern recycling management.
