2. Non-Ferrous Metals • Non-ferrous metals include aluminum, copper, lead, zinc and tin, as well as precious metals like gold and silver. Their main advantage over ferrous materials is their malleability. They also have no …
The non-ferrous metal industry is one of the most important parts of China's process industry and has an extremely important strategic position in the national economy. However, there are many problems in the process of non-ferrous metal smelting: (1) The utilization rate of resource and energy is low in the production process. (2) Large amount of …
What is Non-Ferrous Metal? A non-ferrous metal is a type of metal that does not contain iron in significant amounts or has iron content low enough to be negligible. Unlike ferrous metals, non-ferrous metals lack magnetic properties and are generally more resistant to rust and corrosion, making them ideal for applications exposed to moisture or ...
