  1. 7075-T6 AluminumAir Craft Bolt Chad Allen, Devon Rood, Kurt Core

  2. The Bolt • Connects the aileron to plane.

  3. Why is our alloy used for this product? • Light weight • Hardest Aluminum alloy • High fatigue strength

  4. What the name means • 7000 series aluminum contains zinc as the primary alloying element. • T6 meaning it is heat treated and furnace aged

  5. PercentComposition • Alloying elements: • Zinc-5.6% • Magnesium-2.6% • Copper-1.6% • Impurities: • Iron-0.5% • Silicon-0.4% • Manganese-0.3% • Chromium-0.26% • Aluminum-88.74 (remainder)

  6. Mechanical Properties • Tensile strength 83 KSI • Yield Strength 73 KSI • Brinell hardness-172 • Rockwell B-87 • Fatigue strength 23 KSI(500,000,000 cycles)

  7. Manufacturing Process • Heat treated and furnace aged • Salt bath • Cold water quench • Rolled threads • http://www.youtube.com/watch?v=kidWBeyOMA0

  8. Interesting Information • Aerospace bolts are not normally made of 7075-T6 aluminum • There is a thin invisible oxide that prevents the metal from oxidization • Zinc lowers the corrosive resistance.
