1200

Grade 1200 has been largely replaced by the 1050 grade of aluminium. The 1200 has a 99.0% minimum requirement for aluminium content but is still classed as a non-heat treatable commercially pure Aluminium. The mechanical, physical and fabrication properties of the materials are very similar, with the only real noticeable difference being the 1200 has a slightly higher strength but a lower conductivity value.

Therefore please also refer to the data sheet of 1050 for specific information regarding the processing and application areas for this material (click here for 1050 data sheet)
