Produced billets: 110”, 127”, 152”, 178”, 203” in diameter, max 6,000 mm in length, and in addition to standard alloys (1050, 1070, 6060, 6063, 6463, 6005 and 6082), alloying can also be done according to customer demand.
6XXX Series Alloys
Profiles produced for architectural purposes are generally produced from 6XXX alloys by extrusion method. As mentioned above, AA 6XXX series alloys contain magnesium (Mg) and silicon (Si), and the ratios of other impurities (such as Fe, Cu, Mn, Zn) along with Mg and Si give different properties to the alloys.
For example, 6XXX alloys with an iron (Fe) content of 0.20% or less are more suitable for obtaining a shiny surface. High iron ratios should be preferred for obtaining a matte surface.
Among the 6XXX series (AlMgSi) alloys, the most commonly used in the architecture - construction sector are 6060 and 6063 (EN and new TS notation) and AlMgSi0.5 (DIN and old TS notation).
Their chemical compositions are generally the same, but they show nuance differences in the lower and upper limits.
If we compare 6005, 6005A alloys with 6063; harder, has stronger mechanical properties, but is more expensive, more difficult to extrude, and therefore makes complex geometries difficult or prevents production.
6005A alloy profiles can be anodized for protection purposes, but the surface quality makes it difficult to obtain a decorative appearance.
This alloy is not as successful as 6063 in terms of plastic shaping ability.
6060 alloy is the most suitable alloy for optimal surface quality as a result of surface treatment for situations where strength is not the most important criterion. It is preferred for decorative priorities such as furniture profiles.
6063 alloy; Application areas: It has application areas such as architectural sections in window, door and facade systems, furnishings, frame systems, lighting, steps, rail electronic modules, electro motor frames, connection elements, coolers, radiators, pneumatics, irrigation, furniture profiles. 6063’ün, 6060’’ can be said to be a little harder but more difficult to extrude.
Characteristic features: Its corrosion resistance is high, its weldability is very good, its fatigue resistance is high, it can be cold formed, it can be shaped in complex geometries.
6082 alloy has a little better impact toughness compared to 6005 but its tendency to decorative anodizing is a little worse. Other properties are similar to 6005 and 6005A alloys. To reiterate:
EN AW / AA 6082 alloy, when compared to 6063; is harder, has stronger mechanical properties, but is more expensive, more difficult to extrude, and therefore makes complex geometries difficult or prevented.
Profiles manufactured from 6082 alloy can be anodized for protection purposes, but the surface quality makes it difficult to obtain a decorative appearance. This alloy is not as successful as 6063 in terms of plastic shaping ability.
Application areas: Heavy structures in railway wagons, truck guardrails, shipbuilding sector, bridges, bicycles, boilers, platforms, flanges, hydraulic parts, pylons, ship masts, awning pipes, rivets
Characteristic features: High corrosion resistance, very good weldability, suitable for machine construction, very good cold forming ability in stabilized form after T4 heat treatment good, fatigue strength is medium, not suitable for complex parts.
Alloy 6101 can be suitable for profiles with high electrical conductivity and also high hardness. 1XXX series alloys also have high electrical conductivity, but 6101 is better in terms of cutting and processing, and the tensile strength of 6101 alloy is also better than 1XXX series.
Alloy 6463 It is the most suitable alloy for obtaining bright aluminum.
