why quality ceramic more difficult to observed under optical microscope if compare with metal?
There are many ways of arranging atoms in three-dimensional space to form crystals, particularly in the case of ceramic materials where there are multiple elements with different character. In the case of metals and alloys the structures tend to be r...
Different Metals?
Sheet metal is metal that has been rolled to a specific thickness. Its usually plain steel, but it can be made in other materials. Welding material is probably what they use to weld metal together. Welding material (or welding rods) are made from a m...
