Two lightweight, high-strength structural metals widely used in aerospace and defense applications.
Beryllium: Beryllium is irreplaceable for defense radar, satellite mirrors, and nuclear applications. The U.S. remains the world's primary producer, but supply is extremely limited and the material is highly toxic to process.
Titanium: Titanium is essential for aerospace and defense manufacturing — commercial aircraft contain up to 15% titanium by weight. Medical implants require titanium's unique biocompatibility.
Beryllium: Beryllium is an extremely light, rigid, and thermally stable metal used in aerospace, defense, and telecommunications. It is the lightest structural metal, used in satellites, radar windows, and nuclear weapon components. Titanium: Titanium is a lightweight, high-strength metal with excellent corrosion resistance. It is used in aerospace, military, medical implants, and sporting equipment. Titanium's strength-to-weight ratio is the highest of any metal.
As tracked by Critical Minerals HQ, Beryllium is currently $960 USD/kg and Titanium is $5,000 USD/t. The two minerals are quoted in different units (USD/kg vs USD/t), so see the live price panels above for the most recent figures.
Neither is "better" in absolute terms — each is engineered for different end-uses. Beryllium is primarily used for: Aerospace structural components and satellite mirrors, Nuclear reactor moderators and reflectors, Defense radar windows and guidance systems, Beryllium-copper alloys for springs and contacts. Titanium is primarily used for: Aerospace structural components and airframes, Military aircraft and naval vessels, Medical implants (hip, knee, dental), Sporting equipment and consumer products. The right mineral depends on the application.
Beryllium and Titanium are quoted in different units (USD/kg vs USD/t), so a direct numeric rarity comparison from spot price alone is indicative only. See the indexed 25-year chart on the live page for relative scarcity behavior.
Specific US import-reliance percentages are not in our on-file reference text for either Beryllium or Titanium. See the official USGS Mineral Commodity Summaries for the latest figures.
Beryllium top producers (USGS): United States, China, Kazakhstan, Mozambique. Titanium top producers: China, Japan, Russia, Kazakhstan. The mineral whose first-listed producer accounts for a larger share of global output carries the greater supply-chain concentration risk.
