Unlike the very high-strength 7075, 7005 is formulated to weld well and keep useful properties in the as-welded condition, which is why it appears in boat hulls, rail vehicles, and welded frames. Its strength is higher than 6061 and close to, though generally below, 7075.<\/p>\n<h2>Available 7005 Aluminum Products<\/h2>\n<h3>Lastra \/ Bobina<\/h3>\n<table>\n<thead>\n<tr>\n<th>Parametro<\/th>\n<th>Spessore<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Spessore<\/td>\n<td>0,3 \u2013 150 mm<\/td>\n<\/tr>\n<tr>\n<td>Larghezza<\/td>\n<td>500 \u2013 2600 mm<\/td>\n<\/tr>\n<tr>\n<td>Lunghezza<\/td>\n<td>500 \u2013 16000 mm<\/td>\n<\/tr>\n<tr>\n<td>Tempre<\/td>\n<td>O, T5, T53, T6<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Tubo<\/h3>\n<table>\n<thead>\n<tr>\n<th>Parametro<\/th>\n<th>Spessore<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Diametro esterno<\/td>\n<td>6 \u2013 300 mm<\/td>\n<\/tr>\n<tr>\n<td>Spessore della parete<\/td>\n<td>0,5 \u2013 40 mm<\/td>\n<\/tr>\n<tr>\n<td>Lunghezza<\/td>\n<td>fino a 12000 mm<\/td>\n<\/tr>\n<tr>\n<td>Tempre<\/td>\n<td>O, T5, T53, T6<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Barra \/ Tondino<\/h3>\n<table>\n<thead>\n<tr>\n<th>Parametro<\/th>\n<th>Spessore<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Diametro<\/td>\n<td>3 \u2013 300 mm<\/td>\n<\/tr>\n<tr>\n<td>Lunghezza<\/td>\n<td>fino a 12000 mm<\/td>\n<\/tr>\n<tr>\n<td>Tempre<\/td>\n<td>O, T5, T53, T6<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Specifiche e denominazioni equivalenti<\/h2>\n<table>\n<thead>\n<tr>\n<th>Denominazione<\/th>\n<th>Riferimento<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>6\u2013400 mm<\/td>\n<td>A97005<\/td>\n<\/tr>\n<tr>\n<td>EN AW<\/td>\n<td>EN AW-7005 \/ AlZn4.5Mg1.5Mn<\/td>\n<\/tr>\n<tr>\n<td>Norme comuni<\/td>\n<td>ASTM B221, EN 755, GB\/T 3191<\/td>\n<\/tr>\n<tr>\n<td>Serie<\/td>\n<td>7000 (Al-Zn-Mg)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Composizione chimica<\/h2>\n<table>\n<thead>\n<tr>\n<th>Elemento<\/th>\n<th>Contenuto (wt%)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Silicio (Si)<\/td>\n<td>0.35 max<\/td>\n<\/tr>\n<tr>\n<td>Ferro (Fe)<\/td>\n<td>0,40 max<\/td>\n<\/tr>\n<tr>\n<td>Rame (Cu)<\/td>\n<td>0,10 max<\/td>\n<\/tr>\n<tr>\n<td>Manganese (Mn)<\/td>\n<td>0.20 &#8211; 0.50<\/td>\n<\/tr>\n<tr>\n<td>Magnesio (Mg)<\/td>\n<td>1.00 &#8211; 1.80<\/td>\n<\/tr>\n<tr>\n<td>Cromo (Cr)<\/td>\n<td>0.06 &#8211; 0.20<\/td>\n<\/tr>\n<tr>\n<td>Zinco (Zn)<\/td>\n<td>4.00 &#8211; 6.50<\/td>\n<\/tr>\n<tr>\n<td>Zirconio (Zr)<\/td>\n<td>0.08 &#8211; 0.20<\/td>\n<\/tr>\n<tr>\n<td>Titanio (Ti)<\/td>\n<td>0.01 &#8211; 0.06<\/td>\n<\/tr>\n<tr>\n<td>Altri, ciascuno<\/td>\n<td>0,05 max<\/td>\n<\/tr>\n<tr>\n<td>Altri, totale<\/td>\n<td>0,15 max<\/td>\n<\/tr>\n<tr>\n<td>Alluminio (Al)<\/td>\n<td>Equilibrio<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Propriet\u00e0 meccaniche in base al trattamento termico<\/h2>\n<table>\n<thead>\n<tr>\n<th>Temperamento<\/th>\n<th>Resistenza a trazione (MPa)<\/th>\n<th>Snervamento (MPa)<\/th>\n<th>Allungamento (%)<\/th>\n<th>Resistenza a taglio (MPa)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>T6<\/td>\n<td>510 &#8211; 570<\/td>\n<td>440 &#8211; 500<\/td>\n<td>4 &#8211; 10<\/td>\n<td>280 \u2013 380<\/td>\n<\/tr>\n<tr>\n<td>T53<\/td>\n<td>470 &#8211; 540<\/td>\n<td>400 &#8211; 460<\/td>\n<td>4 &#8211; 10<\/td>\n<td>280 \u2013 380<\/td>\n<\/tr>\n<tr>\n<td>T5<\/td>\n<td>450 &#8211; 510<\/td>\n<td>380 &#8211; 440<\/td>\n<td>6 &#8211; 12<\/td>\n<td>260 &#8211; 340<\/td>\n<\/tr>\n<tr>\n<td>O<\/td>\n<td>\u2264 220<\/td>\n<td>\u2264 110<\/td>\n<td>\u2265 14<\/td>\n<td>\u2264 140<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Guida alla scelta della tempra<\/h2>\n<h3>T6<\/h3>\n<p>Peak strength for demanding welded or bolted structures.<\/p>\n<h3>T53<\/h3>\n<p>Stress-relieved for improved dimensional stability after welding; common in welded frames.<\/p>\n<h3>T5<\/h3>\n<p>Cooled from extrusion and aged; strong and economical for general structures.<\/p>\n<h3>O<\/h3>\n<p>Annealed for heavy forming before fabrication.<\/p>\n<h2>Caratteristiche principali<\/h2>\n<h3>Saldabilit\u00e0<\/h3>\n<p>Excellent; widely used in welded assemblies that must stay strong after fabrication.<\/p>\n<h3>Marine corrosion resistance<\/h3>\n<p>Good resistance suitable for boat hulls and offshore structures with proper finishing.<\/p>\n<h3>La forza<\/h3>\n<p>Higher than 6061, below 7075.<\/p>\n<h3>Fatigue performance<\/h3>\n<p>Good for cyclic-loaded transport structures.<\/p>\n<h2>Applicazioni<\/h2>\n<ul>\n<li>Marine hulls, frames, and superstructures<\/li>\n<li>Rail and metro vehicle bodies<\/li>\n<li>Welded sporting-goods structures<\/li>\n<li>Bridges and architectural welded frames<\/li>\n<\/ul>\n<h2>Note sulla lavorazione e sulla finitura superficiale<\/h2>\n<p>7005 welds readily with TIG\/MIG using 5356 filler; post-weld artificial aging (T53\/T6 route) can restore strength.

It offers good corrosion resistance and excellent weldability, which is why it is common in boat hulls and frames. Use proper finishing and avoid galvanic contact with dissimilar metals.<\/p>\n<h3>How does 7005 compare to 6061?<\/h3>\n<p>7005 is stronger and welds to higher retained strength, at some cost in corrosion margin versus 6061. Choose 7005 where load and weld performance dominate.<\/p>\n<h3>What filler is used for welding 7005?<\/h3>\n<p>5356 filler is typical for TIG\/MIG welding of 7005. Confirm filler and post-weld treatment with your fabrication spec.<\/p>\n<h2>Domande frequenti generali sugli ordini<\/h2>\n<h3>Qual \u00e8 il tempo di consegna tipico per ordini personalizzati di alluminio?<\/h3>\n<p>Dimensioni e trattamenti personalizzati vengono solitamente spediti entro 10-60 giorni.
