Eight Common Myths About Titanium

Common misconceptions about titanium and titanium alloys are listed as some of the more typical errors:
Myth #1: Titanium conducts heat faster than aluminum
Positive solution: titanium's thermal conductivity is very low, and stainless steel close to about 1/14 of aluminum, iron 1/5. cooking is easy to paste is caused by this reason.
Myth two: high purity titanium hardness is very large
Positive: pure titanium hardness is very small, less than 120 Brinell hardness. But trace impurities can significantly improve its hardness, outdoor use are its alloys.

Myth No. 3: Titanium is a rare metal, the earth's content is very small.
Positive solution: the content of titanium accounts for 0.6% of the earth, accounting for the ninth.
Myth No. 4: Titanium has a smaller specific gravity than aluminum.
True: Titanium has a density of 4.51, while aluminum is less than 2.7. Aluminum pans are heavier because they are too thick! I especially miss the old round aluminum lunch boxes!
Myth No. 5: Titanium is chemically inactive.
True: Dense titanium is relatively stable in air, but is chemically active at high temperatures and can interact strongly with halogenated elements, oxygen, sulfur, carbon, nitrogen, hydrogen, water vapor, carbon monoxide, carbon dioxide, and ammonia. Be careful when dry burning outdoors!
Myth No. 6: Titanium metal is very corrosion resistant to strong acids and alkalis
Positive: Titanium is easily dissolved in hydrofluoric acid, concentrated sulfuric acid, concentrated hydrochloric acid and aqua regia; it does not dissolve in alkali solutions, but it can interact strongly with molten alkali.
Myth No. 7: titanium is not easy to oxidize
Positive solution: titanium metal and aluminum are as easy to oxidation reaction, generate oxide film, prevent further oxidation. Anodizing process is also easy to carry out.
Myth No. 8: The vast majority of the world's titanium products are used in aerospace and heavy industry and other fields.
Solution: Most of the titanium ore produced in the world every year is used for the production of titanium dioxide pigments.
