A great World Postcard Day card from Oregon.
Albany is a city of 57 000 in Linn County. Albany calls itself "the rare metals capital of the world." Mines produce zirconium, hafnium, and titanium.
Zirconium (Zr) is used as an alloying agent in materials that are exposed to aggressive environments such as surgical appliances, light filaments, and watch cases.
Hafnium (Hf) is used in filaments and electrodes
Titanium (Ti) is used to produce a lustrous transition metal with a silver colour, low density, and high strength, resistance to corrosion in sea water, aqua regia, and chlorine. It can be alloyed with iron, aluminum, vanadium, and molybdenum to produce strong, lightweight alloys for aerospace, military, industrial processes, automotive, agriculture, medical prostheses, orthopaedic implants, dental and endodontic instruments, dental implants, sporting goods, jewelry, mobile phones, and other applications.
