spore: profile id: aluminium-3003 spore_version: 0.2 family: aluminium-alloys name: Aluminium alloy 3003 abbreviation: '3003' role: general-purpose wrought alloy category: metals type: aluminium summary: | 3003 is a wrought aluminium-manganese alloy (UNS A93003, alternate designation 3.0517) with 1.0 to 1.5 wt% manganese and 0.05 to 0.20 wt% copper, aluminium as the balance. The Smiths datasheet says it is 20% stronger than 1100 and rates its corrosion resistance very good; the aircraftmaterials page rates it excellent. Strength depends on temper: the aircraftmaterials table gives 14 to 19 ksi tensile in O and 27 ksi minimum in H18, and Smiths gives 110 MPa tensile for the O condition. best_for: Sheet and formed parts that need moderate strength, good workability and weldability, and resistance to atmospheric corrosion, such as storage tanks, chemical equipment and heat exchangers, with the temper named weakest_at: Strength depends on temper, from 14 to 19 ksi tensile in O to 27 ksi minimum in H18, and no seawater rating or measured corrosion rate for 3003 was found in the sources read identity: formula: 'Al-Mn-Cu wrought alloy (3003). Composition limits in wt%: Mn 1.0 to 1.5, Cu 0.05 to 0.20, Fe max 0.70, Si max 0.60, Zn max 0.10, Mg max 0.05, each other element max 0.05 and total others max 0.15, Al remainder' source: smith3003 where: Chemical Composition (weight %) table, Smiths 3003 datasheet.

The file stores them as printed and does not decide the basis. - The aircraftmaterials page title also names 3003A. That is a separate grade, and no code was taken from it. - Smiths 5052 values are for the H32 condition. They are used only in the comparison text, not as 3003 values. - 'Source type: all 3003 strength and physical values come from two distributor datasheets (Smiths and AircraftMaterials).

The element-level PubChem data for aluminium and manganese is in the hazards list, but no toxicity or dust data for the alloy was found. gap: Hazard classification of 3003 as supplied, and of dust or fume from machining or welding, was not found in a source opened in this run. points: - label: What the sources cover line: The datasheets describe strength, corrosion, workability and specifications, not health effects. Before cutting, grinding or welding, read the supplier safety data sheet for the exact product. - title: If it fails lead: The one failure route read in this run is loss of ductility in harder tempers. It comes from datasheet values, not from field or test failure records. points: - label: Bending harder tempers line: The aircraftmaterials table gives 4 % elongation in H16 and H18 against 25 % in O, and a minimum 90-degree bend radius of 1 1/2 to 3 T for H18. - title: Handling and storage points: - label: Temper line: Name the temper and the specification on every order, and check it on receipt. Smiths lists ASTM B 209 for sheet, and AMS 4006 and AMS 4008 for 3003-0 and H-14 sheet. - label: Bending line: Choose the temper from the bend radius needed. O, H12 and H14 bend at 0 T, H16 needs 1/2 to 1 1/2 T and H18 needs 1 1/2 to 3 T. why: Aluminium alloy 3003 is a wrought alloy in the 3xxx (manganese) series. Manganese, at 1.0 to 1.5 wt%, is the main addition. The aircraftmaterials page says it makes 3003 20% stronger than alloy 1100, and that the alloy keeps the corrosion resistance and workability of commercially pure aluminium. The temper code (for example O, H14 or H18) records the cold work given, and this profile keeps each temper apart. Smiths lists storage tanks, chemical equipment, cooking and kitchen equipment and heat exchangers as its typical uses. uses: - where: Heat exchangers line: Smiths lists heat exchangers among typical applications. - where: Storage tanks and chemical equipment line: Smiths and the aircraftmaterials page both list these uses. - where: Cooking and kitchen equipment line: Smiths and the aircraftmaterials page both list cooking and kitchen equipment. This is a consumer use, not a space use. can_do: - label: Strength by temper value: 14 to 19 ksi (O) up to 27 ksi min (H18) tensile line: Tensile strength rises from 14 to 19 ksi in O, through 17 to 23 ksi in H12, 20 to 26 ksi in H14 and 24 to 30 ksi in H16, to 27 ksi minimum in H18 (aircraftmaterials, 0.064 in sheet, each temper kept separate). - label: Yield by temper value: 5 ksi (O) to 24 ksi (H18) line: The yield column gives 5 ksi in O, 12 ksi in H12, 17 ksi in H14, 21 ksi in H16 and 24 ksi in H18 (ksi min, as printed). - label: Elongation value: 25 % (O) to 4 % (H16, H18) line: Elongation in 2 in falls from 25 % in O to 6 % in H12, 5 % in H14 and 4 % in H16 and H18. Smiths gives 25 % in O on a 50 mm gauge. - label: Stiffness and weight value: 2.73 g/cm3 and 69.5 GPa (O) line: In the O condition, density is 2.73 g/cm3 and the modulus of elasticity is 69.5 GPa (Smiths). - label: Heat conduction value: 190 W/m.K (O) line: Thermal conductivity is 190 W/m.K in the O condition (Smiths). - label: Thermal expansion value: 23.1 ppm/K (O) line: Smiths prints 23.1x10-6 /K for the O condition, which is 23.1 ppm/K. - label: Melting point value: 655 °C line: Smiths gives a single melting point of 655 °C. A solidus and liquidus range is not printed. - label: Formability value: 0 T (O, H12, H14) to 1 1/2 to 3 T (H18) minimum 90-degree bend line: The minimum 90-degree cold bend radius for 0.064 in sheet is 0 T in O, H12 and H14, 1/2 to 1 1/2 T in H16 and 1 1/2 to 3 T in H18. - label: Corrosion resistance value: very good (Smiths) and excellent (aircraftmaterials) line: Smiths rates atmospheric corrosion resistance very good, and the aircraftmaterials page says excellent. Neither gives an environment, exposure time or rate. - label: Weldability value: very good (Smiths) line: The Smiths datasheet rates 3003 very good for weldability. No welding procedure or joint data was read. compare: Compared with 5052, the two datasheets read here point in different directions. The Smiths 5052 datasheet says that, when annealed, 5052 is stronger than 1100 and 3003, and it rates 5052 very good against seawater and marine atmospheres. The Smiths 3003 datasheet gives no seawater rating, only very good resistance to atmospheric corrosion. The two records use different tempers (O for 3003 here, H32 for 5052 in its Smiths table), so they do not give a like-for-like strength ranking, and this profile makes none. The main addition is manganese for 3003 and magnesium for 5052. On these sources 5052 has the printed seawater rating. See the aluminium-5052 profile for its own values. compare_rows: - label: Density benchmark: density - label: Thermal conductivity benchmark: thermal_conductivity - label: Thermal expansion benchmark: cte handling: - Name the temper and the specification on every order. Smiths lists ASTM B 209 for sheet, and AMS 4006 and AMS 4008 for 3003-0 and H-14 sheet. - Choose the temper from the bend radius you need. O, H12 and H14 form at 0 T, H16 needs 1/2 to 1 1/2 T and H18 needs 1 1/2 to 3 T (aircraftmaterials, 0.064 in sheet). - Read the supplier safety data sheet before cutting, grinding or welding. The PubChem data are element-level only. - Smiths rates the weldability very good. No welding procedure, filler or joint data for 3003 was read in this run. good_for: - Sheet and formed parts that need moderate strength, good workability and weldability, and atmospheric corrosion resistance, with the temper named. - Storage tanks and chemical equipment, listed by both Smiths and the aircraftmaterials page, and heat exchangers, listed by Smiths. - Light parts where O or H12 is needed for tight bends. watch_out: - 'Strength depends on temper: tensile runs from 14 to 19 ksi in O to 27 ksi minimum in H18, so always name the temper.' - The Smiths O-temper values (110 MPa tensile, 50 MPa proof stress) and the aircraftmaterials ksi table are different sources on the same temper, and both are datasheet values, not design allowables. - No design allowables, such as ASTM B 209 minimum strengths, were read, so the values here are not for design. - The sources disagree on minimum manganese (Smiths 1.10, aircraftmaterials 1.0) and on corrosion wording (very good against excellent). The file keeps each printed value and names its source. - No measured seawater corrosion rate or galvanic data for 3003 was found. - No H24 values were found in any source read, so H24 is not recorded. verdict: 3003 is a general-purpose manganese alloy whose strength is set by its temper, and two datasheets rate its atmospheric corrosion resistance very good or excellent. Name the temper on every order, bend within the minimum radius for that temper, and treat the corrosion wording as a datasheet claim until a measured rate is read.
