I have been happy with online metals: www.onlinemetals.com Depending on what size you're looking for, can be cheaper than mcmaster-carr, though the smallest diameter available from them is 3/8"
By the way, they only stock 7075-T651. What's the difference? Excerpted from http://www.rotory.com/ubbthreads/showflat.php?Cat=&Board=UBB2&Number=38346&page=4&view=collapsed&sb=5&o=&fpart=1, "The temper designation appears as a hyphenated suffix to the basic alloy number. An example would be 7075-T73 where -T73 is the temper designation. Four basic temper designations are used for aluminum alloys. They are -F: as fabricated; -0: annealed; -H: strain hardened and -T: thermally treated. A fifth designation, -W, is used to describe an as—quenched condition between solution heat treatment and artificial or room temperature aging. Following is a list of tempers which define aluminum alloys. . (many omitted) . -T6: Solution heat treated and then artificially aged. Mechanical property limits not affected by cold working. Most alloys in the -w and -T4 conditions artificially aged to -T6. . (others omitted) . -T651: Solution heat treated, stress-relieved by stretching and artificially aged. Equivalent to -T6 and applies to plate and rolled bar’ except 2219." -- Chachi639 ------------------------------------------------------------------------ Chachi639's Profile: http://www.rcgroups.com/forums/member.php?action=getinfo&userid=40731 View this thread: http://www.rcgroups.com/forums/showthread.php?threadid=315327 RCSE-List facilities provided by Model Airplane News.
