These two alloys are often confused as being almost the same, which is almost true. They are both nickel alloys and share many key characteristics. AL6XN and Alloy 20 are alike in that they each retain their strength to about 1000°F. In addition they both perform well, in salt water environments, providing excellent resistance to crevice and pitting corrosion as well as stress corrosion cracking. This is where their similarities actually end. In this brief newsletter, we’ll highlight key differences between AL6XN and Alloy 20, so you’ll know when to select one alloy over the other.
