The flat bar form factor is particularly suited for structural brackets, supports, guide rails, and machined components where a rectangular profile is required. 2024 alloy provides one of the highest strength-to-weight ratios among aluminum alloys, making it a preferred material in aerospace and high-performance engineering applications.<\/p>\n<p>Flat bars are typically supplied in T3 and T351 tempers for maximum strength, or in O temper for applications requiring subsequent forming. The T851 temper is used for components requiring elevated temperature stability.<\/p>\n<h2>Available 2024 Aluminum Flat Bar Products<\/h2>\n<h3>Standard Flat Bar Sizes<\/h3>\n<table>\n<tr>\n<th>Liga met\u00e1lica<\/th>\n<th>Temperamento<\/th>\n<th>Largura (mm)<\/th>\n<th>Espessura (mm)<\/th>\n<th>Comprimento (mm)<\/th>\n<\/tr>\n<tr>\n<td>2024 Flat Bar<\/td>\n<td>O, T3, T4, T351, T851<\/td>\n<td>10-300<\/td>\n<td>3-80<\/td>\n<td>1000-6000<\/td>\n<\/tr>\n<tr>\n<td colspan=\"5\">Custom dimensions available on request<\/td>\n<\/tr>\n<\/table>\n<h3>Common Size Combinations<\/h3>\n<table>\n<tr>\n<th>Largura (mm)<\/th>\n<th>Espessura (mm)<\/th>\n<th>Typical Application<\/th>\n<\/tr>\n<tr>\n<td>25<\/td>\n<td>5<\/td>\n<td>Structural brackets, supports<\/td>\n<\/tr>\n<tr>\n<td>40<\/td>\n<td>8<\/td>\n<td>Machine parts, guide rails<\/td>\n<\/tr>\n<tr>\n<td>50<\/td>\n<td>10<\/td>\n<td>Fittings, mounting plates<\/td>\n<\/tr>\n<tr>\n<td>75<\/td>\n<td>15<\/td>\n<td>High-stress structural components<\/td>\n<\/tr>\n<tr>\n<td>100<\/td>\n<td>20<\/td>\n<td>Aerospace structural parts<\/td>\n<\/tr>\n<tr>\n<td>150<\/td>\n<td>30<\/td>\n<td>Heavy-duty brackets, tooling<\/td>\n<\/tr>\n<\/table>\n<h2>Especifica\u00e7\u00f5es e Designa\u00e7\u00f5es Equivalentes<\/h2>\n<table>\n<tr>\n<th>Padr\u00e3o<\/th>\n<th>Designa\u00e7\u00e3o<\/th>\n<\/tr>\n<tr>\n<td>AA (US)<\/td>\n<td>2024<\/td>\n<\/tr>\n<tr>\n<td>EN (Europe)<\/td>\n<td>EN AW-2024<\/td>\n<\/tr>\n<tr>\n<td>DIN (Germany)<\/td>\n<td>3.1355 \/ AlCu4Mg1<\/td>\n<\/tr>\n<tr>\n<td>ISO<\/td>\n<td>AlCu4Mg1<\/td>\n<\/tr>\n<tr>\n<td>UNS<\/td>\n<td>A92024<\/td>\n<\/tr>\n<tr>\n<td>GB (China)<\/td>\n<td>2A12<\/td>\n<\/tr>\n<tr>\n<td>JIS (Jap\u00e3o)<\/td>\n<td>A2024<\/td>\n<\/tr>\n<\/table>\n<h2>Composi\u00e7\u00e3o qu\u00edmica<\/h2>\n<table>\n<tr>\n<th>Elemento<\/th>\n<th>Conte\u00fado (%)<\/th>\n<\/tr>\n<tr>\n<td>Si<\/td>\n<td>0,50 m\u00e1x<\/td>\n<\/tr>\n<tr>\n<td>Fe<\/td>\n<td>0,50 m\u00e1x<\/td>\n<\/tr>\n<tr>\n<td>Cu<\/td>\n<td>3.8-4.9<\/td>\n<\/tr>\n<tr>\n<td>Mn<\/td>\n<td>0.30-0.90<\/td>\n<\/tr>\n<tr>\n<td>Mg<\/td>\n<td>1.2-1.8<\/td>\n<\/tr>\n<tr>\n<td>Cr<\/td>\n<td>0,10 m\u00e1ximo<\/td>\n<\/tr>\n<tr>\n<td>Zn<\/td>\n<td>0,25 m\u00e1ximo<\/td>\n<\/tr>\n<tr>\n<td>Ti<\/td>\n<td>0,15 m\u00e1ximo<\/td>\n<\/tr>\n<tr>\n<td>Outros (cada)<\/td>\n<td>0,05 m\u00e1ximo<\/td>\n<\/tr>\n<tr>\n<td>Outros (total)<\/td>\n<td>0,15 m\u00e1ximo<\/td>\n<\/tr>\n<tr>\n<td>Al<\/td>\n<td>Equil\u00edbrio<\/td>\n<\/tr>\n<\/table>\n<h2>Propriedades Mec\u00e2nicas por T\u00eampera<\/h2>\n<table>\n<tr>\n<th>Propriedade<\/th>\n<th>2024-O<\/th>\n<th>2024-T3<\/th>\n<th>2024-T351<\/th>\n<th>2024-T851<\/th>\n<\/tr>\n<tr>\n<td>Resist\u00eancia \u00e0 tra\u00e7\u00e3o, m\u00e1xima (MPa)<\/td>\n<td>186<\/td>\n<td>483<\/td>\n<td>462<\/td>\n<td>517<\/td>\n<\/tr>\n<tr>\n<td>Resist\u00eancia \u00e0 tra\u00e7\u00e3o, rendimento (MPa)<\/td>\n<td>76<\/td>\n<td>345<\/td>\n<td>324<\/td>\n<td>455<\/td>\n<\/tr>\n<tr>\n<td>Resist\u00eancia ao cisalhamento (MPa)<\/td>\n<td>124<\/td>\n<td>283<\/td>\n<td>262<\/td>\n<td>276<\/td>\n<\/tr>\n<tr>\n<td>Alongamento na ruptura (%)<\/td>\n<td>20<\/td>\n<td>18<\/td>\n<td>17<\/td>\n<td>7<\/td>\n<\/tr>\n<tr>\n<td>Dureza (Brinell)<\/td>\n<td>47<\/td>\n<td>120<\/td>\n<td>120<\/td>\n<td>137<\/td>\n<\/tr>\n<\/table>\n<h2>Guia de Sele\u00e7\u00e3o de Tempero<\/h2>\n<table>\n<tr>\n<th>Temperamento<\/th>\n<th>Caracter\u00edsticas<\/th>\n<th>Typical Use for Flat Bar<\/th>\n<\/tr>\n<tr>\n<td>O<\/td>\n<td>Annealed, maximum formability, lowest strength<\/td>\n<td>Forming, bending, subsequent machining before heat treatment<\/td>\n<\/tr>\n<tr>\n<td>T3<\/td>\n<td>Solution heat-treated, cold worked, naturally aged.
