It is valued for excellent weldability, good corrosion resistance, and strong fatigue performance, making it a common choice for welded transport and structural assemblies. Compared with 7075 it offers slightly lower peak strength but better fabrication behavior, especially in marine or humid service. Linsy supplies 7020 in sheet, plate, tube, bar, and wire with full mill certificates and a range of tempers for welding and structural use.<\/p>\n<h2>Available 7020 Aluminum Products<\/h2>\n<h3>Lastra \/ Piastra<\/h3>\n<p><strong>Tempere disponibili:<\/strong> T5, T6, T651<\/p>\n<table>\n<tr>\n<th>Temperamento<\/th>\n<th>Spessore (mm)<\/th>\n<th>Larghezza (mm)<\/th>\n<th>Lunghezza (mm)<\/th>\n<\/tr>\n<tr>\n<td>T5, T6, T651<\/td>\n<td>0.5 \u2013 150<\/td>\n<td>500 \u2013 2600<\/td>\n<td>500 \u2013 16000 (taglio su misura)<\/td>\n<\/tr>\n<\/table>\n<h3>Tubo<\/h3>\n<p><strong>Tempere disponibili:<\/strong> T5, T6, T651, O<\/p>\n<table>\n<tr>\n<th>Temperamento<\/th>\n<th>Diametro esterno (mm)<\/th>\n<th>Spessore parete (mm)<\/th>\n<th>Lunghezza (mm)<\/th>\n<\/tr>\n<tr>\n<td>T5, T6, T651, O<\/td>\n<td>6 \u2013 300<\/td>\n<td>0.5 \u2013 40<\/td>\n<td>500 \u2013 12000<\/td>\n<\/tr>\n<\/table>\n<h3>Barra \/ Tondino<\/h3>\n<p><strong>Tempere disponibili:<\/strong> T5, T6, T651, O<\/p>\n<table>\n<tr>\n<th>Temperamento<\/th>\n<th>Diametro (mm)<\/th>\n<th>Lunghezza (mm)<\/th>\n<\/tr>\n<tr>\n<td>T5, T6, T651, O<\/td>\n<td>3 \u2013 300<\/td>\n<td>500 \u2013 12000<\/td>\n<\/tr>\n<\/table>\n<h3>Filo<\/h3>\n<p><strong>Tempere disponibili:<\/strong> T5, T6, T651, O<\/p>\n<table>\n<tr>\n<th>Diametro (mm)<\/th>\n<th>Peso della bobina<\/th>\n<th>Tolleranza<\/th>\n<\/tr>\n<tr>\n<td>0.8 \u2013 30<\/td>\n<td>Min. 50 kg<\/td>\n<td>\u00b1 0,02 mm<\/td>\n<\/tr>\n<\/table>\n<h2>Specifiche e denominazioni equivalenti<\/h2>\n<p>7020 aluminum (EN AW-7020, AlZn4.5Mg1) is supplied to common wrought-alloy specifications.
