Chromium [PDF ebook] 

Chromium isn’t the most well-known metal, but it’s very useful. In fact, chromium could even be called a supermetal. Chromium makes other metals better. From mining chromium to the making of chromium alloys, this book, a complement to any science curriculum, is a valuable look at this precious element. Vivid photographs, detailed captions, and "Metal Mania" fact boxes inform readers about the importance of chromium.
