Sl.No. Synosis Points
1 In this new version of the standard, the international alloy designations, many of which are widely used in the country, have been added in accordance with the teal sheets issued by the Aluminium Association. The Indian standard designations which were there in the standard have been retained but they have been given new designations in line with the international system of nomenclature considering the nearest equivalent alloy. A Table giving the old and new designations of these alloys have also been included in the Annex A. Some alloys have also been added based on specific customer / industry requirements for those alloys.
2 IS 1285:2023 covers extruded round tubes and hollow sections for general engineering purposes while IS 733:1983 covers bars, rods and solid sections for general engineering purposes. For all the specific information related to alloy composition and mechanical properties, IS 1285:2023 gives reference of IS 733:1983. Furthermore, the manufacturing process, process flow, testing, in-process controls, etc. for both hollow and non-hollow extruded sections are similar. Therefore, it is felt that there is no need to have separate standards for hollow and non-hollow extruded sections. In view of the above, this standard has been prepared by including the requirements for hollow and non-hollow extruded sections. Hence, IS 1285 shall stand withdrawn subsequently. IS 733:2025 is intended to cover all types of extruded profiles of wrought aluminium and aluminium alloys.
