Jewelry Tips: A very common element, titanium remained unknown until the late 19th century and had no industrial value until the mid-20th, when economical processing methods were developed (a happy coincidence, as the then-expanding aerospace industry found titanium indispensable). Discovered in the late 18th Century, tungsten or wolfram, was first distilled from the mineral wolframite. Its high melting point is prized for things like light bulb filaments; added to other metals, it forms super dense alloys used in products ranging from golf club heads to weapons. Both are strong as steel–titanium at about half the weight, tungsten at about twice the weight–and able to alloy with numerous other metals, making them indispensable to modern industry.
