During the brazing cycle the cladding melts and flows to seal joints, while the 6951 core keeps the assembly strong and formable. It is widely specified in automotive and HVAC heat exchangers.<\/p>\n<h2>Available 6951 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, T4, T6, T651<\/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>Stati di fornitura comuni<\/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>Stati di fornitura comuni<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Filo<\/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>0.8 &#8211; 30 mm<\/td>\n<\/tr>\n<tr>\n<td>Peso della bobina<\/td>\n<td>min 50 kg<\/td>\n<\/tr>\n<tr>\n<td>Tempre<\/td>\n<td>O, 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>A96951<\/td>\n<\/tr>\n<tr>\n<td>EN AW<\/td>\n<td>EN AW-6951<\/td>\n<\/tr>\n<tr>\n<td>Norme comuni<\/td>\n<td>ASTM B209, ASTM B210, EN 573, GB\/T 3190<\/td>\n<\/tr>\n<tr>\n<td>Serie<\/td>\n<td>6000 (Al-Mg-Si brazing core)<\/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>0.20 &#8211; 0.50<\/td>\n<\/tr>\n<tr>\n<td>Ferro (Fe)<\/td>\n<td>0,80 max<\/td>\n<\/tr>\n<tr>\n<td>Rame (Cu)<\/td>\n<td>0.15 &#8211; 0.40<\/td>\n<\/tr>\n<tr>\n<td>Manganese (Mn)<\/td>\n<td>0,10 max<\/td>\n<\/tr>\n<tr>\n<td>Magnesio (Mg)<\/td>\n<td>0,40 \u2013 0,80<\/td>\n<\/tr>\n<tr>\n<td>Cromo (Cr)<\/td>\n<td>0,05 \u2013 0,20<\/td>\n<\/tr>\n<tr>\n<td>Zinco (Zn)<\/td>\n<td>Famiglia<\/td>\n<\/tr>\n<tr>\n<td>Titanio (Ti)<\/td>\n<td>0,15 max<\/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<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>T6<\/td>\n<td>270 &#8211; 310<\/td>\n<td>230 \u2013 270<\/td>\n<td>8 \u2013 12<\/td>\n<\/tr>\n<tr>\n<td>T4<\/td>\n<td>200 \u2013 240<\/td>\n<td>120 &#8211; 160<\/td>\n<td>14 &#8211; 18<\/td>\n<\/tr>\n<tr>\n<td>O<\/td>\n<td>\u2264 160<\/td>\n<td>\u2264 70<\/td>\n<td>\u2265 18<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Guida alla scelta della tempra<\/h2>\n<h3>O<\/h3>\n<p>Soft core for maximum formability before brazing; often the as-clad supplied condition.<\/p>\n<h3>T4<\/h3>\n<p>Solution heat treated and naturally aged; good forming plus moderate strength.<\/p>\n<h3>T6 \/ T651<\/h3>\n<p>Peak strength after artificial aging; used where the core must carry load after brazing.<\/p>\n<h2>Caratteristiche principali<\/h2>\n<h3>Brazeability<\/h3>\n<p>Engineered to survive vacuum and controlled-atmosphere brazing with low core erosion.<\/p>\n<h3>Conducibilit\u00e0 termica<\/h3>\n<p>Good heat transfer for compact cooling systems.<\/p>\n<h3>Resistenza alla corrosione<\/h3>\n<p>Resists atmospheric and chemical attack for long service life.<\/p>\n<h3>Formabilit\u00e0<\/h3>\n<p>Forms into fins, manifolds, and intricate heat-exchanger shapes.<\/p>\n<h2>Applicazioni<\/h2>\n<ul>\n<li>Automotive radiators, heaters, oil coolers<\/li>\n<li>HVAC condensers and evaporators<\/li>\n<li>Cryogenic heat-transfer equipment<\/li>\n<li>Electronics heat sinks and thermal modules<\/li>\n<\/ul>\n<h2>Note sulla lavorazione e sulla finitura superficiale<\/h2>\n<p>6951 is normally supplied as clad brazing sheet (core plus 4343\/4045 cladding) for furnace brazing.
