Generally more costly than ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity, non-magnetic property or resistance to corrosion.
Any solid metal that can be melted can be cast. Foundries are the factories that do this casting work, developing expertise with a handful of metals and methods, and designing standard products to maximize value and efficiency in production. Metals and casting methods influence each other: the best casting choice for a product is influenced by how its metal will behave in molten, cooling, and solid states.ENQUIRY NOW
