Depending on how it is heat-treated treated, or strengthened via the tempering process, the mechanical properties of 6061 aluminum alloy vary. The strength ratings for this alloy will be derived from 6061-T6, a commonly used temper for aluminium plate and bar stock, in order to simplify this article. It has a 68.9 GPA (10,000 ksi) modulus of elasticity and a 26 GPA shear modulus. These numbers represent the stiffness or resistance to deformation of the alloy. This alloy is typically simple to weld together and readily deforms into the majority of needed shapes, making it a flexible production material. The yield strength and ultimate strength are two crucial elements when thinking about mechanical qualities. The maximum stress required to elastically deform the part in a specific loading configuration is described by the yield strength (tension, compression, twisting, etc.). The maximum amount of stress a material can endure before breaking is known as its ultimate strength, on the other hand (undergoing plastic or permanent deformation). According to industry-standard standard design procedures, the yield strength is the most significant design restriction for static applications; nevertheless, the ultimate strength can be useful for some applications that require it. The yield tensile strength of 6061 aluminium alloy is 276 MPa (40000 psi), while its ultimate tensile strength is 310 MPa (45000 psi).
WHY IS 6061 T6 ALUMINUM GRADE T6 THE MOST POPULAR?
One of the most widely used grades of aluminium, 6061, is frequently used for structural applications, welded assembly, electronics, and a range of commercial and domestic products. High to moderate strength, exceptional corrosion resistance, and superior machine ability and weld ability are all features of 6061 aluminium tube, bar, and plate. For applications requiring durable yet lightweight material, 6061 aluminium is preferred above other alloys in the 6xxx series due to its higher strength. One of the most popular forms of 6061 aluminium is 6061 T6. Precipitation hardening results in the temper or level of hardness known as T6. This grade is heat treatable and has a strong strength-to-weight ratio. It is utilised for engineering and structural applications, boats, furniture, and other things because of its excellent formability and weld ability.
