1. “ E very new beginning comes from some other beginning’s end” Nothing new is being told or presented in this paper that which has not been told or presented earlier by someone somewhere about application of High Strength Aluminium Alloy extrusion in Defence FOREWORD

6. Manifold increase in the demand for military hardware results in the corresponding increase in the use of Aluminum Alloy extrusions. Present-day scenario in the country More than 250 active extruders produce variety of extrusions for varied applications but T only 2 or 3 private players alone produce meager quantity strategic High strength Aluminum Alloy

7. Customer-specific consumption pattern indicates that: M aximum share goes to E xtrusion thus E xtrusion process is vital in feeding input material for Defence application Extrusion process can produce : Rods Plates Profiles Seamless tubes Hollow sections and Graphts Trend indicates that: Rods are consumed maximum

8. Eight series of High Strength Aluminium Alloys Classification is based on the addition of major alloy 1 x x x - Pure Aluminium 2 x x x - Copper based alloys 3 x x x - Manganese-based alloys 4 x x x - Silicon-based alloys 5 x x x - Magnesium-based alloys 6 x x x - Magnesium-Silicon-based alloys 7 x x x - Copper-Magnesium-Zinc-based alloy 8 x x x - Miscellaneous alloys 2 x x x and 7 x x x - Falls under the category of High strength Aluminum Alloy

13. Consumption pattern of extruded materials a view ! Consumption figures are only approximate and based on the Consumption pattern date of 2009-10

14. Opportunities Despite self-sufficiency in commercial grade Aluminum Alloy, the need to emphasise on opportunities arise owing to 2 or 3 private players in the country produce High Strength Aluminium Alloy for Defence applications .

15. Production of High Strength Alumionium Alloy is mostly confined to Ordnance Factories, whose production meets part of their internal use that is assisted to some extent by importation.
