It is the European counterpart to the more widely known <strong>aleaci\u00f3n 3003<\/strong> \u2014 sharing the same Al-Mn base, but with a slightly tighter copper limit (0.10% max) for improved corrosion performance in certain environments.<\/p>\n<p>Belonging to the 3xxx series, 3103 is a <strong>aleaci\u00f3n no tratable t\u00e9rmicamente, endurecible por deformaci\u00f3n<\/strong>. Its mechanical properties are developed entirely through cold working (H tempers) rather than high-temperature thermal treatment. This makes temper selection the primary lever for adjusting strength and formability: O temper offers maximum ductility for deep drawing, while H14 and H16 provide structural strength for roofing, cladding, and formed components.<\/p>\n<p>3103 matches 3003 in virtually all performance characteristics \u2014 corrosion resistance, density, thermal and electrical conductivity \u2014 making it the default specification in European markets where EN designation is required. It is widely used in <strong>corrugated roofing, heat exchangers, chemical equipment, kitchen utensils, and general sheet metal fabrication<\/strong>.<\/p>\n<h2>Available 3103 Aluminum Products<\/h2>\n<h3>3103 Aluminum Sheet &amp; Coil<\/h3>\n<p>Sheet and coil are the dominant supply forms for 3103.

The manganese content contributes to a uniform, protective surface oxide. The tighter copper limit (0.10% max vs. 3003) provides marginally better performance in certain mildly acidic or condensation-prone environments.<\/p>\n<h3>Formabilidad<\/h3>\n<p>In the O temper, 3103 exhibits outstanding formability suitable for deep drawing, stretching, and bending. Work-hardened tempers (H1x) progressively reduce formability but can still be bent, roll-formed, and stamped with appropriate tooling and bend radii. Minimum bend radius for H14 temper is approximately 0.5\u20131\u00d7 thickness for 90\u00b0 bends.<\/p>\n<h3>Soldabilidad y Uni\u00f3n<\/h3>\n<p>3103 can be welded by gas welding, resistance welding, and brazing. TIG and MIG welding are feasible but may require filler alloys (e.g., 4043 or 4047) to reduce hot-cracking risk. Brazing and soldering work well with appropriate flux. Mechanical fastening (riveting, bolting) is reliable in all tempers. For welded structures requiring consistently sound fusion welds, consider 5xxx series alloys as an alternative.<\/p>\n<h3>Thermal &amp; Electrical Conductivity<\/h3>\n<p>Like other Al-Mn alloys, 3103 offers good thermal conductivity (approximately 160 W\/m\u00b7K at room temperature) and moderate electrical conductivity (approximately 40% IACS in O temper). These properties, combined with formability and corrosion resistance, make it a popular choice for heat exchanger and radiator applications.<\/p>\n<h3>Endurecimiento por Deformaci\u00f3n<\/h3>\n<p>As a non-heat-treatable alloy, 3103 gains all its strength from cold working. The work-hardening rate is moderate \u2014 faster than pure aluminum (1xxx) but slower than 5xxx alloys. Annealing at 345\u00b0C followed by slow cooling restores full softness for reworking.<\/p>\n<h2>Aplicaciones comunes<\/h2>\n<ul>\n<li><strong>Corrugated roofing and siding:<\/strong> A primary market for 3103 H14\/H16 sheet in European construction \u2014 combining weather resistance, light weight, and ease of roll-forming.<\/li>\n<li><strong>Heat exchangers and radiators:<\/strong> Fin stock, tube plates, and headers \u2014 leveraging thermal conductivity, formability, and corrosion resistance.<\/li>\n<li><strong>Chemical and process equipment:<\/strong> Storage tanks, piping, vessels, and ducting for compatible media at moderate temperatures.<\/li>\n<li><strong>Cooking and kitchen utensils:<\/strong> Pots, pans, baking trays, and food-processing equipment \u2014 where formability in O temper and corrosion resistance in service are valued.<\/li>\n<li><strong>Fabricaci\u00f3n general de chapa met\u00e1lica:<\/strong> Brackets, enclosures, cabinets, housings, and sign panels \u2014 an all-purpose workhorse for formed parts.<\/li>\n<li><strong>Automotive components:<\/strong> Heat shields, trim panels, and non-structural formed parts.<\/li>\n<li><strong>Embalaje:<\/strong> Light-gauge foil and container applications where formability is the primary requirement.<\/li>\n<\/ul>\n<h2>Notas sobre el procesamiento y el acabado superficial<\/h2>\n<p><strong>Corte:<\/strong> 3103 sheet and plate can be sheared, slit, or saw-cut with standard aluminum tooling.

The key difference is chemical: 3103 limits copper to 0.10% max (per EN 573-3), while 3003 allows 0.05\u20130.20% Cu (per ASTM B209). 3103 is the European designation (EN AW-3103); 3003 is the American designation (AA 3003). Both are interchangeable in most applications.<\/p>\n<p><strong>Q: What is the 3103 equivalent in Chinese standards?<\/strong><\/p>\n<p>A: Under GB\/T 3190, the alloy 3003 is the functional equivalent of 3103. Both are Al-Mn alloys with overlapping composition ranges. For Chinese-market projects specifying &#8220;3003,&#8221; 3103 material can generally be substituted with mutual agreement. Confirm with your end-user specification before substitution.<\/p>\n<p><strong>Q: Can 3103 aluminum be anodized?<\/strong><\/p>\n<p>A: 3103 is not a preferred anodizing alloy. The manganese content can produce a gray or mottled anodic coating rather than the clear, bright finish expected from 5xxx or 6xxx alloys. For decorative or architectural anodizing, consider 5005, 5052, or 6063.<\/p>\n<p><strong>Q: Is 3103 suitable for welding?<\/strong><\/p>\n<p>A: 3103 welds well with gas welding, resistance welding, and brazing. TIG and MIG welding are feasible but may require filler metal (e.g., 4043) to mitigate hot-cracking risk. For consistently welded structures, consider 5052 or 5083 as an alternative.<\/p>\n<p><strong>P: \u00bfCu\u00e1l es la cantidad m\u00ednima de pedido?<\/strong><\/p>\n<p>A: Linsy operates with flexible MOQs.
