· Zinc (Zn) is an abundant metal, found in the Earth's crust, with a myriad of industrial and biological uses. At room temperature, zinc is brittle and blue-white in color, but it can be polished to a bright finish. A base metal, zinc is primarily used to galvanize steel, a process that protects the metal against unwanted corrosion.
· The production of metallic filters also takes advantage of this ability. Pure copper powder is used in the electrical and the electronics industries because of its excellent electrical and thermal conductivities. Alloyed with tin, zinc, nickel and other elements, copper in powder form is used in structural parts and friction materials.
