Commercial aluminium alloy grade 1200 has high corrosion resistance with slightly higher strength than 1050a. The alloy also boasts high thermal conductivity and reflectivity although this is not quite as high as 1050. The alloy has a 99% minimum requirement for aluminium content and yet is still classed as a non-heat treatable commercially pure aluminium. Grade 1200 has been largely replaced by grade 1050a.
Alloy 1200 is typically used for:
