( Third Revision )

0. FOREWORD

0.1 This Indian Standard ( Third Revision ) was adopted by the Indian Standards Institution on 25 August 1983, after the draft finalized by the Light Metals and Their Alloys Sectional Committee had been approved by the Structural and Metals Division Council.

0.2 This standard was first issued in 1956 and subsequently revised in 1967 and 1975. Further revision became necessary as three new materials were required to be included as they found wide application in different industries. The main modifications made in the standard are as follows:

4 A new high strength alloy 76528 has been included.

b)

Aluminium of 99.6 chemical, compositions

purity 19600 of 19000 and

has been included 19500 aluminium

and the have been

modified to align them with the requirements of IS : 2590-

1979*.

4 For both heat-treatable and non-heat treatable alloys, the pro-

perties in the `0' temper have been specified as maximum.

0.3 Some characteristics and typical uses of the alloys covered in the standard have been listed in Appendix A.

0.4 The major alloying elements have been printed in bold face in the chemical composition ( see Table 1 ).

0.5 For the purpose of deciding whether a particular requirement of this standard is complied ,with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2- 196Ot. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

*Primary aluminium ingots for remelting for general engineering purposes ( jFttt rzuistRioun)l.es for roundingoff numerical values ( revisrd ).

1. SCOPE

1.1 This standard covers requirements for wrought aluminium and aluminium alloy bars, rods and sections for general engineering purposes.

2. TERMINOLOGY

2.1 For the purpose of this standard, the definitions given in IS : 5047( Part 1 )-1979 to IS : 5047 ( Part 3 )-1979* shall apply. Some of the

important definitions are reproduced below for ready reference.

2.1.1 Bars - Any solid section other than round, that is long in relation to cross section and whose width or greatest distance between parallel

faces is greater than 6 mm.

2.1.2 Rod - A round solid section which is long in relation to cross section having a diameter greater than 6 mm.

2.1.3 Regular Solid Section - A solid rolled, drawn or extruded section other than round, polygonal or rectangular, which can be conveniently divided into approximate rectangles with measurable dimensions, for example, angles, channels, tees, etc.

2.1.4 Irreelar Solid Section - A solid rolled, drawn or extruded section, the profile of which cannot be divided readily into approximate rectangles

or measurable dimensions.

2.1.5 Heat-Treatment Batch - A quantity of material of one alloy, of the

same dimensions and produced in the same way, solution-treated and

subsequently precipitation-treated

in one furnace load. More than one

heat treatment batch may comprise a furnace load.

3. SUPPLY OF MATERIAL

3.1. General requirements for the supply of aluminium alloy products shall conform to IS : 1387-1967t.

and aluminium

4. FREEDOM FROM DEFECTS

4.1 The material shall be sound and free from harmful defects.

4.2 For aluminium copper and aluminium-zinc-magnesium-copper

alloys,

which are susceptible to peripheral grains coarsening, the permissible

limit of `coarse grain' envelope shall be as agreed to between the manu-

facturer and the purchaser.

*Glossary of terms relating to aluminium and aluminium alloys: Part 1 Unwrought and wrought metals (first revision ). Part 2 Plant and operations, thermal treatment, control, testing and finishing. Part 3 Geometrical properties and tolerances, structural and surface dc fc cts.
