The alloy is one of the aluminium-silicon-magnesium (Al-Si-Mg) alloys and is particularly suited to machining and structural applications.<\/p>\n<p>6060 T6 is a moderate strength material for the machinery and construction industries, with high formability.<\/p>\n<p><strong>Machinability:<\/strong> It stands out in particular for high machinability and good weldability. It is relatively easy to machine and is suited to a variety of machining methods.<\/p>\n<p><strong>Turning and milling:<\/strong> Cutting speed \u2014 it can be machined at medium cutting speeds. Cutting tools \u2014 good results are obtained with carbide inserts or hardened steel tooling. Cooling \u2014 a good cutting fluid is recommended during machining.<\/p>\n<p><strong>Weldability:<\/strong> It has excellent welding properties and can readily be welded by the TIG and MIG methods. The material to be welded should be clean and care should be taken so that thermal stress does not arise during welding.<\/p>\n<p><strong>Heat treatment:<\/strong> It is generally processed by hot or cold forming. When heat treatment is applied the material can gain a certain hardness, although the natural properties of the alloy are generally sufficient in themselves.<\/p>\n<div style=\"border:1px solid

The cycle is: solution treatment \u2192 quench \u2192 ageing. Hardening comes from Mg2Si precipitation. In 6060 there are two separate production routes and they must not be confused: (a) for T6\/T66, solution treatment in a SEPARATE FURNACE at 525-540 \u00b0C, quench, then artificial ageing; (b) for T5 THERE IS NO SEPARATE SOLUTION TREATMENT \u2014 as it leaves the extrusion press the profile is already at solution temperature and it is cooled at the press exit by air or water (PRESS QUENCH); only artificial ageing follows. In EN 515 the definition of T5 is exactly &#8216;cooled from an elevated temperature shaping process and artificially aged&#8217;. The diagram is schematic, the time axis is NOT to scale, and no curve is drawn because no published TTT\/CCT curve was used. The difference between T5 and T6 is not the ageing but the SOLUTION TREATMENT route: in T5 it happens at the press exit, in T6 in a separate furnace. That is why T6 gives higher and more repeatable values while T5 is cheaper. T64 and T66 are not different ageing temperatures but different levels of CONTROL within the same family: T64 is controlled underageing and T66 a controlled raised property level. The diagram is schematic; the time axis is not to scale.<\/div>\n<\/div>\n<p><!-- \/dm-diy-isil --><\/p>\n<p style=\"margin:0 0 12px;font-size:15px;line-height:1.75;\"><b>The temper system of 6060 is a product of European extrusion practice and has no one-to-one equivalent in the ASTM world.<\/b> <b>T64 and T66<\/b> in particular are European tempers defined by EN 515; you will not find them on an American datasheet.

Is that right?<\/p>\n<p style=\"margin:0 0 12px;font-size:15px;line-height:1.75;\"><b>No, and the difference reaches the contract.<\/b> In the old DIN 1725 world both were called <b>AlMgSi0.5<\/b>, and that name still circulates today. But <b>EN 573-3 defines them as two separate alloys<\/b>, and the distinction is essentially in <b>magnesium<\/b>: the Mg band of 6060 is <b>0.35-0.60 %<\/b> while 6063 runs at a higher Mg level.<br \/><b>The consequence shows up directly in the EN 755-2 minima.<\/b> Profile, T6, thin wall: <b>6060 Rm \u2265190 N\/mm\u00b2, 6063 Rm \u2265215 N\/mm\u00b2<\/b>.

Same section, same temper, <b>a 13-14 % difference in strength<\/b>.<br \/><b>Practical consequence:<\/b> if you calculated with 6063 values and the supplier shipped 6060, <b>your profile is not below standard but your calculation is void<\/b>. Read the alloy number on the certificate, not the DIN name; <b>a certificate that says &#8220;AlMgSi0.5&#8221; does not tell you which alloy you received<\/b>. Always write <b>EN AW-6060<\/b> or <b>EN AW-6063<\/b> into the order text, never the old DIN name. The same logic applies on the tolerance side: <b>EN 12020-2 covers both<\/b>, so the tolerance standard does not tell you which alloy you bought either.<\/p>\n<p style=\"margin:18px 0 6px;font-size:15px;font-weight:700;color:#12303f;line-height:1.5;\">Our fa\u00e7ade profiles came out of anodizing streaked and banded.
