Aluminium Alloy 6082 T651

Aluminium alloy 6082 is a medium strength alloy with excellent corrosion resistance. It has the highest strength of the 6000 series alloys. Alloy 6082 is known as a structural alloy. In plate form, 6082 is the alloy most commonly used for machining. As a relatively new alloy, the higher strength of 6082 has seen it replace 6061 in many applications. The addition of a large amount of manganese controls the grain structure which in turn results in a stronger alloy. 6082-T651 is now superseding low-carbon steels in structural applications where the benefits of lightness, specific stiffness, corrosion resistance and ease of fabrication can be exploited
