As mentioned above, tungsten is the strongest natural metal (142,000 psi). But tungsten is weak in impact strength — it's a brittle metal known to shatter on impact. On the other hand, Titanium has a tensile strength of 63,000 psi. Titanium, however, doesn't stand a chance against bullets fired from high-powered military-grade firearms such as those used to penetrate tanks. Titanium can take single hits from high-calibre bullets, but it shatters and becomes penetrable with multiple hits from military-grade, armour-piercing bullets. Titanium and most titanium alloys are readily weldable, using several welding processes. Properly made welds in the as-welded condition are ductile and, in most environments, are as corrosion-resistant as the base metal. However, on average, Titanium has similar strength properties to stainless steel but weighs about 40% less, is non-magnetic, and is more heat-resistant. Its cold working expenses are significantly greater than those of stainless steel and more prone to scratches. It is recommended that one should not combine different metals in orthopaedic devices. The least noble metal in such a galvanic coupling is more likely to corrode. However, some studies have failed to show increased corrosion when Titanium and stainless steel are combined. While Titanium is one of the most abundant metals on the earth's surface, platinum is rare. This rarity makes platinum extremely valuable. Titanium Dioxide powders or specks of dust may react violently with CHEMICALLY ACTIVE METALS (such as POTASSIUM, SODIUM, MAGNESIUM and ZINC).
