Of around 50 metallic minerals, a few make up the great majority of specimens. This gallery includes their color, streak, Mohs hardness, other distinguishing characteristics, and chemical formula. Streak, the color of the powdered mineral, is a truer indication of color than the surface appearance, which can be affected by tarnish and …
Magnesium oxidizes very quickly so it must be surface treated. Also, it can be difficult to machine and can even react violently with oxygen, so extra care is required when machining this material. 7. Gold. Probably the very first medical metal, gold has good corrosion resistance and biocompatibility.

These instruments have a metal or plastic case and use leads similar to those found in wood cased pencils. The lead, lodged in a metal spiral inside the case, is held in place by a rod with a metal stud fastened to it. When the cap is twisted, the rod and stud move downward in the spiral, forcing the lead toward the point.
