  The earth's mantle is not made of metal but is a mixture of many somewhat molten rocks, most as oxides, meaning the mantle may be more oxygen than metal. The metals it â¦ has the most of are magnesium, iron, and aluminum. There's also lots of silicon, which is not really a metal. 6 people found this useful.

Fiber lasers. Fiber lasers are monolithic by design; producing single mode, high quality beams which are ideal for narrow kerf, precision cutting (typically less than 0.050 material thickness), narrow welds, narrow but deep penetration welds and remote welding of small precision parts.isk lasers use a sealed modular design to produce high beam quality multimode laser light with BPP of 2 - 4 mm*mrad. Applications over 1kW usually require larger cutting kerfs to expel the molten metal, or slightly larger spots to cover larger weld seams.
