3003 Aluminum Sheet & Coil

The supplier's 3003 listing (AA3003) publishes coil and sheet in tempers H0, H12, H14, H16, H18, H22, H24, H26 and H28, thickness 0.2–6.0 mm, width 80–2300 mm and length 100–11000 mm, with mother coil in DC or CC form and about 0.3–2.5 tons per pallet in its packed format. Unusually for this catalogue, the 3003 page also publishes regular sheet sizes: 1.0×1219×2438, 2.0×1220×2440, 3.0×1200×2400, 3.0×1200×3600, 2.5×1250×2500, 3.0×1500×3000 and 2.0×1500×3600 — the standard sheet formats buyers most often ask for by name.

3003's published footprint in this catalogue is wider than its grade page. It is a named alloy in the circle plate list (3003 circles), in the lubricated foil listing for air duct and food container work (1100/3003/8011), in the air duct strip listing, in the stucco embossed sheet family (3000 series), in the polished sheet listing, and as the core alloy of the 4343/3003/7072 clad brazing material on the brazing sheet page. That spread is why 3003 is the default answer to general sheet enquiries in this range: roofing and cladding, duct work, cookware, general fabrication.

The temper list deserves one note: H28 is published on the 3003 listing but not on the 1xxx listings, and the H2x tempers (H22–H28) are the strain-hardened and annealed-back tempers often chosen for drawn and formed parts. The temper guide explains the code system behind these designations.

Ordering 3003

3003 enquiries divide into coil and cut sheet. For cut sheet, start from the published regular sizes — the seven formats in the table are the ones the listing holds as standard, and a requirement that matches one of them quotes faster than a bespoke format. For coil, the figures are the grade envelope (0.2–6.0 mm, 80–2300 mm) with the temper named from the full published set. Either way, the packed weight figure on the listing — about 0.3–2.5 tons per pallet — is worth checking against your unloading equipment before the order is finalised.

Because 3003 also feeds the brazing clad (as the 3003 core of the 4343/3003/7072 composite), the duct strip listings and the stucco family, a 3003 enquiry that names the end use helps the reply route it correctly: plain 3003 sheet, 3003 for cladding, and 3003 duct strip are three different quotations in this catalogue even though the alloy is the same.

One last 3003 note: the grade is also the core of the clad brazing composite and a stucco and tread family alloy (3000 series), so a buyer qualifying 3003 sheet is qualifying the base metal of the clad brazing composite and of the stucco and tread family at the same time.
