IS 737:2008 is the Indian Standard (BIS) for wrought aluminium and aluminium alloy sheet and strip for general engineering purposes. IS 737 specifies wrought aluminium and aluminium alloy sheet and strip for general engineering. It covers 8 alloy grades from pure aluminium (19000) to heat-treatable alloys (63400) in various tempers. Used for roofing, cladding, bus bodies, enclosures, and general fabrication.
Specification for wrought aluminium and aluminium alloy sheet and strip covering grades, temper designations, mechanical properties, dimensional tolerances, and surface quality.

Both specify mechanical properties of aluminium sheet by alloy and temper.
Key Differences
≠IS uses Indian designations (19000, 52000). ASTM/AA uses 1100, 5052. EN uses EN AW-1100, EN AW-5052. Cross-reference: IS 19000 = AA 1100, IS 52000 = AA 5052.
Key Similarities
≈All three use the same temper designation system (O, H, T series) adopted from the Aluminum Association.

19000 (equivalent to AA 1100) is the most widely used grade for roofing, cladding, and general purpose sheet metal work. It is commercially pure aluminium with good formability.
What do the temper designations mean?+
O = annealed (soft), H = strain hardened (H12=1/4 hard, H14=1/2 hard, H18=full hard), T = heat treated (T4=solution treated, T6=peak aged). Higher temper = higher strength but lower ductility.
