As a non-heat-treatable wrought alloy, 3003 derives its strength from cold working rather than precipitation hardening. Square bar is typically produced by extrusion (in H112 or F temper) or fabricated by cutting from strain-hardened sheet or plate stock (in H14, H22, or O temper).<\/p>\n<p>With 1.0\u20131.5% manganese as its primary alloying element, 3003 offers approximately 20% higher strength than commercially pure 1100 aluminum while retaining excellent corrosion resistance, formability, and weldability. Square bar is widely specified for structural framing, machining blanks, decorative applications, tank supports, and general fabrication where a square cross-section is required for ease of fixturing, assembly, or aesthetic preference.<\/p>\n<p>Common tempers for 3003 square bar include <strong>O<\/strong> (totalmente recozido, m\u00e1xima conformabilidade), <strong>H14<\/strong> (half hard, good balance of strength and workability), and <strong>H22<\/strong> (strain-hardened then partially annealed, stable strength with good formability). Linsy supplies 3003 square bars in these tempers with custom side dimensions, cut-to-length, surface finishing, and MTC reports available for every order.<\/p>\n<h2>Available 3003 Aluminum Square Bar \u2014 Dimensions &amp; Tempers<\/h2>\n<p>Linsy supplies 3003 aluminum square bars in standard and custom sizes. Both metric and imperial dimensions are available. Custom cut-to-length, edge conditioning (chamfered or radiused edges), and surface finishing (mill finish, anodized, or brushed) can be specified at order.<\/p>\n<h3>3003 Aluminum Square Bar \u2014 Standard Dimensions<\/h3>\n<table>\n<thead>\n<tr>\n<th>Side (mm)<\/th>\n<th>Comprimento (mm)<\/th>\n<th>kg\/m (Approx.)<\/th>\n<th>Temperamentos Comuns<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>5 \u2013 12<\/td>\n<td>1000 \u2013 4000<\/td>\n<td>0.07 \u2013 0.39<\/td>\n<td>O, H14, H22<\/td>\n<\/tr>\n<tr>\n<td>12 \u2013 25<\/td>\n<td>1000 \u2013 5000<\/td>\n<td>0.39 \u2013 1.69<\/td>\n<td>O, H14, H112<\/td>\n<\/tr>\n<tr>\n<td>25 \u2013 50<\/td>\n<td>1000 \u2013 6000<\/td>\n<td>1.69 \u2013 6.75<\/td>\n<td>O, H22, H112, F<\/td>\n<\/tr>\n<tr>\n<td>50 \u2013 60<\/td>\n<td>1000 \u2013 6000<\/td>\n<td>6.75 \u2013 9.72<\/td>\n<td>H112, F<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Note: Side dimension and length can be customized to your drawing or specification.

The manganese addition suppresses intergranular corrosion, making 3003 square bar suitable for outdoor structural applications, chemical storage, and marine non-critical parts. It performs well in contact with fresh water, mild chemicals, and food products without requiring a protective coating.<\/p>\n<h3>Conformabilidade e Soldabilidade<\/h3>\n<p>3003 square bar in O, H14, or H22 temper can be cold bent, drilled, tapped, and machined with standard tooling. It is rated as highly weldable by TIG (GTAW), MIG (GMAW), and resistance welding. Filler metal 4043 or 1100 is recommended. Note that welding anneals the heat-affected zone in strain-hardened tempers, reducing local strength \u2014 consider using O temper bar if extensive welding is planned.<\/p>\n<h3>Usinabilidade<\/h3>\n<p>3003 has fair machinability \u2014 softer than heat-treatable alloys like 6061 or 2011. Use sharp tools, positive rake angles, and appropriate cutting speeds to avoid built-up edge. O temper machines more smoothly than H14; chip breakers are recommended for continuous cuts. For square bar used as a machining blank, centerless or blanchard grinding may be specified for tighter tolerance surfaces.<\/p>\n<h2>Common Applications of 3003 Aluminum Square Bar<\/h2>\n<table>\n<thead>\n<tr>\n<th>Setor<\/th>\n<th>Aplicativos<\/th>\n<th>Why 3003 Square Bar Is Used<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Processamento qu\u00edmico<\/td>\n<td>Tank supports, pipe brackets, walkway framing<\/td>\n<td>Resist\u00eancia \u00e0 corros\u00e3o, soldabilidade, resist\u00eancia moderada<\/td>\n<\/tr>\n<tr>\n<td>HVAC &amp; Dutos<\/td>\n<td>Duct framing, equipment stands, mounting bars<\/td>\n<td>Formability, corrosion resistance, workability<\/td>\n<\/tr>\n<tr>\n<td>Fabrica\u00e7\u00e3o geral<\/td>\n<td>Machining blanks, spacers, fixturing, brackets<\/td>\n<td>Square cross-section for easy clamping\/jigging, cost-effective<\/td>\n<\/tr>\n<tr>\n<td>Decorative &amp; Architectural<\/td>\n<td>Trim, railing components, display stands, furniture components<\/td>\n<td>Clean square edges, good surface finish acceptance, formability<\/td>\n<\/tr>\n<tr>\n<td>Armazenamento e Transporte<\/td>\n<td>Cargo tie-down bars, rack supports, trailer trim<\/td>\n<td>Weldability, corrosion resistance, cost-effective<\/td>\n<\/tr>\n<tr>\n<td>Food &amp; Beverage Equipment<\/td>\n<td>Washdown frames, equipment supports, conveyor guides<\/td>\n<td>Food-safe, corrosion resistant, easy to clean<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Processing &amp; Surface Finish Notes for 3003 Square Bar<\/h2>\n<p>Linsy can supply 3003 square bar with processing and finishing options applied before delivery:<\/p>\n<ul>\n<li><strong>Corte:<\/strong> CNC band saw, circular saw, or waterjet cutting to custom lengths.
