Special Metals owns both the humble and the extreme ends of nickel alloys. Its Monel (nickel-copper) is the long-standing standard metal for eyeglass frames — solderable, corrosion-resistant and easy to plate — so a large share of the world's metal glasses are made from a Special Metals-trademarked alloy. And its Inconel and related nickel superalloys are the high-temperature metals that jet-engine turbine blades and combustors, gas turbines, and rocket engines are made from: alloys that keep their strength at temperatures that would soften or melt ordinary steel. So one nickel-alloy specialist — owned by Precision Castparts, the Berkshire Hathaway aerospace-metals giant — sits under both the eyewear resting on your face and the engines that fly aircraft. The same metallurgical family, in different formulations, spans a pair of glasses and a turbine spinning at 1,500°C.

Nickel superalloys are a deep aerospace and defense chokepoint. Only a few mills in the world can melt and process the precise superalloy chemistries that jet engines require — alloys like Inconel 718 and single-crystal turbine-blade alloys — and qualifying a new superalloy "heat" for a flight-critical part is a years-long, certification-bound process that cannot be rushed or easily re-sourced. Special Metals, inside Precision Castparts, is one of those few. So the ability to fly, and to build the gas turbines that generate much of the world's electricity, depends on a tiny set of superalloy producers, and the metals themselves rely on scarce strategic inputs (nickel, cobalt, rhenium). It is a textbook deep chokepoint: the airplane and the power plant are both downstream of a handful of specialty-metal mills almost no one outside aerospace metallurgy could name.
