Is Tungsten toxic to humans?

Is Tungsten bulletproof?
The question is, Can a tungsten armor plate effectively protect you against bullets? The simple answer is yes. But we are talking about tungsten alloys however because tungsten itself has the highest melting point of any metal and for that reason would be every difficult to work with in mass production quantities.
What is the strongest metal alloy on earth?
Steel
How much does tungsten cost per kg?
The price of tungsten metal is USD30-100/Kg, depending upon its form and purity.
Can a bullet pierce a diamond?
Yes, but only in unusual circumstances. The other answers have hopefully driven home the difference between hardness and toughness. A bag of diamonds a few inches thick would stop a bullet because shattering the diamonds would use up the bullet’s kinetic energy.
Could a diamond stop a bullet?
Pound for pound, diamonds are not very good at stopping bullets. The energy absorbed by diamond shattering is much less than the energy absorbed by metals deforming. A plate of steel would be better at stopping bullets than a plate of diamond.
What’s the biggest diamond in the world?
On January 25, 1905, at the Premier Mine in Pretoria, South Africa, a 3,106-carat diamond is discovered during a routine inspection by the mine’s superintendent. Weighing 1.33 pounds, and christened the “Cullinan,” it was the largest diamond ever found.
What material can stop a bullet?

Can Oobleck stop a bullet?
Lightweight body armor uses liquid to stop bullets. Upon first examination, oobleck looks and acts like any other liquid. It flows from one cup to another easily like you would expect. However, if you apply sudden, sharp force to the surface, it becomes a near-solid mixture.
Does chainmail actually work?
Chain mail alone is highly effective against slashes. In conjunction with a padded undergarment (gambeson) it will reduce blunt force damage as well, and it is thought that most warriors wore a gambeson, or some kind of leather garment, to enhance the effectiveness of their mail.
