THE outstanding problem in beryllium metallurgy is the lack of ductility exhibited by the metal, both at room temperature and at elevated temperatures. At room temperature, brittleness can be ...

Pure tungsten is a steel-gray metal that with impurities is brittle and not very workable but in pure form is very ductile and easy to work with. Of all metals in pure form, tungsten has the highest ...

Tungsten is a metal in group VIB of the periodic table with atomic number 74, an atomic weight of 183.85, and a density of 19.3 Mg/m 3. Its melting point is 3410 C, and it boils at 5930 C. In the ...

Scientists found tungsten in Tycho Brahe's lab, and they're not sure how it got there. A chemical mystery lurks in the laboratory of Tycho Brahe, one of the most famous astronomers of all time.

LED bulbs suffer less wear-out through power cycling than incandescents, so the conversion is just a division: years of service = ARL/(3*365). For example ... In place of the tungsten filament ...

LED floodlight bulbs are a great way to increase visibility around your home -- with the range and wattage to light up dark corners and garages or illuminate expansive outdoor spaces like porches ...

Lighting can have an enormous impact on the way our homes look and feel. Having the right LED light bulb for each section in your home is important for setting the right tone. You can liven up a ...
