Ramisa Sas handles semi-finished products in magnesium and its main alloys.
Magnesium is the lightest of the main structural metals and, relative to its volume weight, has good strength properties. Its hexagonal metallic structure gives it particular characteristics such as high dimensional stability. Magnesium is very simple to machine, requires lower energy consumption and has good machinability. Magnesium is also easy to weld and equally easy to recycle.
