Strongest Metal in the World. The top 3 contenders for the title of the strongest metal in the world are tungsten, osmium and titanium - however, the top spot doesn't belong to any one of them. The following article explains why and how. There is quite a debate regarding which metal should be crowned as the strongest metal in the world. The controversy is due to the fact that based upon the various physical properties (discussed later in this article), no single metal can be considered as scoring a perfect ten when all parameters are considered.
The sixth strongest metal is another iron alloy, tool steel, with tungsten, molybdenum, chromium and vanadium added. No. 7 is a tungsten alloy with nickel and copper. Eight and nine are a titanium alloy with aluminum added, and a cobalt-chromium alloy with additions of tungsten, nickel, and carbon.he tensile strength of a material is the amount of pulling force that can be applied before it weakens and breaks. If something were suspended from a wire, the amount of weight that could be suspended before the wire snapped would be the wire's tensile strength.
