The documentation found at this specific reference juncture details the core profile of Sodium Chloride: (1:1 ratio of sodium and chloride ions).

Takeaway: Haynes 4.89 is not a general-purpose alloy. It is a specialty material that outperforms titanium at high temperatures and beats standard superalloys on weight. The trade-off is cost and manufacturability. haynes 4.89

I assume you are referring to alloy — though please double-check the exact designation, as the most common Haynes high-temperature alloys are numbered like 188 , 230 , 282 , 25 (L-605), 556 , HR-120 , 214 , etc. There is no widely known standard alloy called "Haynes 4.89" in major materials databases (MatWeb, ASM, Haynes International literature).

Density is the silent killer in engineering. In applications ranging from gas turbine blades to space vehicle landing gear, "every gram counts." Most traditional nickel superalloys (e.g., Inconel 718) have a density around 8.19 g/cm³. Steel sits at roughly 7.8 g/cm³. A material with a density of is incredibly lightweight—closer to titanium (4.5 g/cm³) than to nickel.

If you were actually referring to a specific academic paper regarding the mathematical modeling of a microstructure (where "4.89" might be a specific coefficient or constant in a creep equation for a different Haynes alloy), please provide a bit more context, and I can analyze that specific data point for you. The trade-off is cost and manufacturability
