matters:<\/strong><br>AMS 4173 fixes one alloy and one temper, so a single line on the purchase order settles composition, strength and elongation. There is no temper table to work through and no ambiguity about what the extrusion has to hold.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The T6511 designation carries the process with it. Solution heat treating, stress relieving by stretching and precipitation heat treating are part of the specification, which is what keeps residual stress and straightness predictable in long extruded sections.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Section size only changes elongation. Tensile and yield hold at 38.0 ksi and 35.0 ksi across the range, while elongation goes from 8 percent under 0.250 inch to 10 percent at 0.250 inch and over.<\/p>\n\n<\/div>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><strong>Alfiniti can help:<\/strong><br>Send us the profile, wall and length you need in 6061-T6511.
