Linsy supplies 7075 square bar in T6, T651, T7351 and T7451 tempers for aircraft structures, molds, dies, fixtures and high-stress machine parts where rigidity is non-negotiable. In the T6 and T651 tempers it reaches peak tensile strength (~570 MPa); the T73\/T7351 and T7451 tempers trade some strength for improved resistance to stress-corrosion cracking, which matters for thicker sections and outdoor or corrosive service.<\/p>\n<h2>\uad6c\uc785 \uac00\ub2a5\ud55c 7075 \uc54c\ub8e8\ubbf8\ub284 \uc81c\ud488<\/h2>\n<h3>7075 \uc54c\ub8e8\ubbf8\ub284 \uc0ac\uac01 \ubc14<\/h3>\n<table>\n<tr>\n<th>Side (mm)<\/th>\n<th>\uae38\uc774(mm)<\/th>\n<th>\uc131\uc9c8<\/th>\n<\/tr>\n<tr>\n<td>5 \u2013 200<\/td>\n<td>up to 16,000<\/td>\n<td>O, T6, T651, T7351, T7451<\/td>\n<\/tr>\n<tr>\n<td>Custom sizes available on request<\/td>\n<td>\u2014<\/td>\n<td>\u2014<\/td>\n<\/tr>\n<\/table>\n<h2>\uaddc\uaca9 \ubc0f \ub4f1\uac00 \uc9c0\uc815<\/h2>\n<p>7075 square bar is supplied to ASTM B221 \/ AMS 4154 (T6\/T651) and AMS 4078 (T7351) where applicable, with GB\/T 3191 and EN 754 references available on request.
