The Aluminum Tempers are as follows: (and there are more as well)
T1: Indicates the alloy was cooled from an elevated temperature shaping process like hot rolling, then naturally aged resulting in a stable condition and not subsequently cold worked to increase strength
T2: Like T1 but cold worked and naturally aged.
T3: Solution heat treated, cold worked and naturally aged….Our 2011-T3 example is typically cold drawn and naturally aged in bar products.
T4: Solution heat treated and naturally aged…2017-T4 would not require any cold work between solution treatment and ageing to achieve properties
T5: Cooled from an elevated temperature shaping process and then artificially aged. 6063 – T5 extrusions would be aged after cooling from the extrusion temperature.
T6: Solution treated and artificially aged…Our example of 7075-T6
T7: Solution heat treated and stabilized… 7075-T7351 from our examples.
T8 : Solution heat treated, cold worked, and then artificially aged. 2011-T8 would be an example here
T9 : Ssolution heat treated, artificially aged and then cold worked
T10: Cooled from elevated temperature shaping ,cold worked and then artificially aged.
Inconel 600 is an alloy. It’s a solid solution of its elements and cannot be strengthened by heat treatment. UNS chemical composition designation is N06600. This Cold working will result in increased strength. Heat treatment can remove any undesirable effects of cold work.
Typical Room temperature mechanical properties in the annealed condition are yield strength 30 to 50,000 psi, tensile strength 80 to 100,000 psi, elongation 35 to 55%. Density is .306 pounds per cubic inch.
No, Hastelloy X or Alloy X is Non-Magnetic.
Inconel 625 is a trademark name held by Special Metals Corporation whereas Alloy 625 is a generic name for anyone who produces that same material besides Special Metals. Check out a video here specifically on Inconel 625.
Aermet 100 is made (produced) by Carpenter Technology Corporation and is a trademark name they hold as well. For more information on Aermet check out a video specifically on Aermet 100 here.

15-5 is a grade of precipitation hardening stainless steel. For more info on 15-5 click here.
4340 is a low alloy steel that contains Nickel, Chromium and Molybdenum as strengthening agents.
No Inconel is NOT Titanium. Inconel contains a small amount of Ti but that doesn’t mean that it’s considered Titanium. Titanium is Titanium and Inconel is predominantly Nickel.
Yes, Inconel is heavier than Titanium.
Inconel 625 or the word “Inconel” is a trade name held by Special Metals Corp. Alloy 625 is the common generic name for the alloy when produced by anyone besides Special Metals. Yes, Alloy 625 and Inconel 625 are the same.
