[QUOTE="onetoncrawler, post: 642347, member: 846"] This seems to be brought up a lot still so I figured I would throw some numbers in to help - these are generic T6 properties. The grade of 7075 or 6061 can affect the outcome of how the links survive. Most people aren't going to age their links to get the desired properties so that isn't realistic. typical T6 off the shelf is what most folks run. The Ultimate tensile strength affects the strength of the threads and the overall strength of the links, but the Young's modulus and yield properties affect the elasticity which is what most people have trouble with. 6061 will bend and not return back to the original shape because the material has been yielded. For those that don't know the UTS and the hardness somewhat go hand in hand. So, the increased hardness of 7075 will also prevent scarring from rocks on lowers. As Mo said, if you are looking to save money you can use 6061 uppers as they (should) only see compression and tension loads. You could potentially still rip out a rod end due to the lack of strength in the 6061. On all links you should calculate the wall thickness to ensure you aren't reducing that strength from the original material properties. Each material is a little different, but a good rule of thumb is D/4. as you can see below, 7075 wins on paper. 6061 UTS - 45k Yield - 40k fatigue - 14k shear - 30k 7075 UTS - 75k Yield - 65k fatigue - 23k shear - 48k take this info as you will, I'm sure there are much smarter people on here that can explain this better than I can. Just trying to provide at least a little tech instead of just saying hell no it will never work thumb.gif [/QUOTE]
