Not just the SR-71. Almost 90% of the world's "antimony" is within the borders of the USSR. Now Cold War, War in Viet Nam doesn't stop buisness!!
Antimony is a chemical that contracts in heat and expands in cold! It was a very important element in the process of making "bi-polar" integrated circuits!
Canada has about 3% of the world's antimony. The USA always purchased its antimony from Canada. Never mind the amount of antimony purchased each year was far greater than what Canada mined!

TRIVA -During the Viet Namese War SAMs lock-on and fired at all aircraft that was not of their Air Force. Pan American Air Lines on it's daily flight from Tokyo to New Delhi flew along the PRC/VietNamese border (with permission) and no B-707 was ever lock-up! The short cut save almost 2,000 miles on the trip. - AW&ST

For such a rare element, you wouldn't think it was the #1 alloying element in lead acid car batteries...

suggest you read this:

Additional historical data here:

Quote:

Estimates of the abundance of antimony in the Earth's crust range from 0.2 to 0.5 parts per million. Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb2S3) is the predominant ore mineral of antimony.

The most important use of antimony metal is as a hardener in lead for storage batteries. The metal also finds applications in solders and other alloys. Antimony trioxide is the most important of the antimony compounds and is primarily used in flame-retardant formulations. These flame-retardant applications include such markets as children's clothing, toys, aircraft and automobile seat covers.

Over 3/4 of the world's antimony comes from China, other important sources are South Africa, Russia, and Bolivia. Even the US produces a significant amount as a by-product of gold and silver mining. Only a very small percentage of the antimony we use goes into semiconductors. It certainly doesn't have the strategic significance that titanium has/had, especially in the 60's and 70's.
