Another Tuesday is here so that means it is indestructible stuff day, today it is Tungsten this I have heard of.
In the early days of light bulbs inventors faced a tricky problem, to make bulbs glow they had to make electricity flow through a fine wire or filament.
Filaments made of carbon or platinum soon overheated and broke, meaning light bulbs burned out often but when they tried tungsten they lasted longer and light bulbs really took off.
Tungsten worked so well because it is one of the strongest, hardest and most heat-resistant metal there is. In fact it has the highest melting point of any metal.
Tungsten is also incredibly dense and heavy, if a soccer ball was made of solid tungsten it would weigh more then 100kilos or 220 pounds.
Interesting facts. Have a great week.
ReplyDeleteI knew what it was used for but I had never actually seen a picture of it or realized how heavy it is. :)
