IS 5082:1998 is the Indian Standard (BIS) for wrought aluminium and aluminium alloy wire for general engineering purposes - specification. This standard specifies the requirements for various grades and tempers of wrought aluminium and aluminium alloy wire used for general engineering applications. It covers chemical composition, mechanical properties like tensile strength and elongation, dimensional tolerances, and testing procedures. The standard is essential for material selection, procurement, and quality control of aluminium wire.
Specifies the requirements for wrought aluminium and aluminium alloy wire for general engineering applications.

! Always specify both the alloy designation (e.g., 6063) and the temper condition (e.g., T6) when ordering wire, as mechanical properties vary significantly between tempers.
! Pay close attention to dimensional tolerances in Table 3, especially for applications requiring precise fits, such as fasteners or pins.
! This standard does not cover specifications for filler wire used in welding; refer to dedicated codes like IS 1278 for that purpose.

Key Differences
≠Alloy Designation System: IS 5082 uses a 5-digit numerical system (e.g., 65032) based on the principal alloying elements, whereas international standards like EN and ASTM use a 4-digit system (e.g., 6082).
≠Temper Designations: While the main temper categories (O, H, T) are similar, IS 5082 uses specific Indian designations like 'WP' for solution treated and artificially aged (equivalent to T6), which can differ from the more detailed sub-divisions in ASTM or EN standards.
≠Range of Alloys: IS 5082 lists a specific subset of alloys common for general engineering in the Indian context, which may be less extensive than the comprehensive lists found in ASTM B211 or EN 573-3.
≠Certification and Testing: IS 5082 requires products to conform to Bureau of Indian Standards (BIS) certification mark scheme, whereas international standards have their own respective compliance and marking requirements.
Key Similarities
≈Core Mechanical Properties: Both IS 5082 and its international equivalents specify minimum tensile strength and percentage elongation as the primary mechanical properties to ensure product quality and performance.
≈Chemical Composition Equivalence: The chemical composition limits for corresponding alloys are largely harmonized. For example, the composition of IS alloy 65032 is practically identical to EN AW-6082 and AA 6082.
≈Product Form and Condition: All standards cover wrought aluminium and aluminium alloy wire in various tempers (conditions), such as annealed (O), strain-hardened (H), and heat-treated (T), to suit different engineering applications.
≈Dimensional Control: All standards specify permissible tolerances on diameter to ensure consistency and fit for engineering purposes, although the exact values or tolerance classes may vary.
What are the mechanical properties of Alloy 6063-T6 wire?+
Minimum Ultimate Tensile Strength is 205 MPa and minimum elongation is 8% for diameters up to 25 mm (Table 2).
How is the wire temper designated?+
Temper is designated by letters like 'O' (Annealed), 'H' (Strain-hardened), and 'T' (Thermally treated) followed by numbers to indicate specific conditions, as per Clause 5.
What is the standard tolerance on a 2 mm diameter wire?+
For a 2 mm diameter wire, which falls in the range '>1.25 up to 3.15 mm', the tolerance is ±0.03 mm as per Table 3.
Which alloys are recommended for rivets?+
The standard lists specific alloys and tempers suitable for manufacturing rivets in Annex A, such as 19500, 52000, 53000, and 64430.
