Titanium is a metal — silver-white, very strong, and surprisingly light for how strong it is. That combination is the whole point of it.

Titanium鈦 is a metal是一種金屬—— silver-white銀白色、 very strong非常堅固、 and而且 surprisingly light for how strong it is以它的強度來說輕得驚人。 That combination這種組合 is the whole point of it正是它最厲害的地方。

Because it is strong without being heavy, it goes into aeroplanes and spacecraft, where every extra kilogram costs fuel. It also resists rust and sea water very well, and the human body accepts it, so doctors use it for artificial joints, bone screws and dental implants.

Because因為 it is strong without being heavy它很強卻不重， it它 goes into用在 aeroplanes and spacecraft飛機和太空船上， where every extra kilogram costs fuel在那裡每多一公斤都會多耗油。 It它 also resists rust and sea water very well也非常耐鏽、耐海水侵蝕， and而且 the human body accepts it人體也能接受它， so所以 doctors醫生 use it for用它來做 artificial joints, bone screws and dental implants人工關節、骨釘和植牙。

Sports equipment, glasses frames and expensive laptop cases use it too, partly for the strength and partly because "titanium" sounds impressive.

Sports equipment, glasses frames and expensive laptop cases運動器材、眼鏡框和高級筆電外殼 use it too也會用它， partly for the strength一部分是因為它的強度， and而 partly because部分是因為 "titanium"「鈦」這個詞 sounds impressive聽起來很高級。

It is a chemical element, symbol Ti, and it is usually mixed with other metals to make alloys rather than used pure. As a word it is uncountable, like water or iron: you say "made of titanium", never "a titanium". It works as a describing word in front of another noun — a titanium frame, titanium screws.

It它 is a chemical element是一種化學元素， symbol Ti符號是 Ti， and而且 it它 is usually mixed with other metals通常會跟其他金屬混合 to make alloys做成合金 rather than used pure而不是單獨使用。 As a word作為一個詞， it它 is uncountable是不可數名詞， like water or iron就像 water 或 iron 一樣： you say你會說 "made of titanium"「made of titanium」（鈦製的）， never "a titanium"絕不會說「a titanium」。 It它 works as a describing word可以當形容詞用 in front of another noun放在另一個名詞前面—— a titanium frame鈦框、 titanium screws鈦螺絲。

Advertisers have stretched it into a loose word for "tough and premium", which is why you sometimes see it on products with very little actual titanium in them.

Advertisers廣告商 have stretched it into把這個詞延伸成 a loose word for一個籠統的說法，指 "tough and premium"「堅固又高級」， which is why這就是為什麼 you sometimes see it你有時會看到它 on products with very little actual titanium in them出現在幾乎沒有真正用到鈦的產品上。

It was named after the Titans, the giant gods, for its strength. Say it "tie-TAY-nee-um".
