If you're trying to weld 6061 or 6063 for the first time, here are some tips you may want to consider:ġ. Welding 6061 or 6063 Aluminum Square Tube Like the 6061, the 6063 alloy is also heat treatable but is typically only heat treated to a "T5" temper.Ĭontact us for more information regarding our line of 60 aluminum square tube products, or call us at 80 with any questions that you may have. However, 6063 is different to the extent that it's not as strong as the 6061 and consequently, will take a 90 deg bend without cracking. Like 6061, 6063 has good corrosion properties, is easily anodizable, and weldable.
The extruded flat bar conforms to 6061-T6511 whereas the plate is a 6061-T651 product and because of the extra "1" at the end of the designation, the customer has to re-order the correct material and re-machine the part.Ħ063 is considered the "architectural" grade within the 6000 aluminum series. More often than we would like, people will order a piece of extruded flat bar of 6061 aluminum only to have it rejected by their customer's quality control department because they were supposed to order a plate product. Although there are many possible processes that can occur, the most common are stress relieving by stretching and straightening, which is referred to as "T6511," whereas "T651" means signifies that no additional straightening has been performed after the stress relieving stretching process has been completed.Īlthough this may sound like a lot of metallurgical mumbo-jumbo, we come across this question quite frequently when people are trying to find material to match what's specified on a print. Many times, you'll see additional letters following the T6 designation and those letters refer to the processes that are performed after heat treating. The “T6" designation is the hardest temper that the 6061 alloy can achieve. The higher the "T" or temper designation, the longer the heat-treat time and usually the harder the material. It is the affordability, weldability and machinability that make it such a popular choice of steel for consumers.6061 Aluminum Square Tube Temper DesignationsĦ061 is a heat treatable alloy that is oven baked to increase its overall hardness.
Mild steel is a type of carbon steel with a low amount of carbon – it is actually also known as “low carbon steel.” Mild steel is not an alloy steel and therefore does not contain large amounts of other elements besides iron you will not find vast amounts of chromium, molybdenum, or other alloying elements in mild steel. Less carbon means that mild steel is typically more ductile, machinable, and weldable than high carbon and other steels, however, it also means it is nearly impossible to harden and strengthen through heating and quenching. The lack of alloying elements such as those found in stainless steels means that the iron in mild steel is subject to oxidation (rust) if not properly coated. Size : 6000mm(l) x 76mm x 38mm, with a wall thickness of 1.6mm Our Mild Steel tube is manufactured to the highest standards and it is easy to cut, drill or weld and can be painted or galvanised after fabrication to increase corrosion resistance. Rectangular tube is available in a large selection of diameters and wall thickness options. Rectangular Tube – 76mm x 38mm – 1.6mm – Mild Steel
