Aluminum is composed of bauxite and alumina. Pure (99%) Aluminum melts at 1220 degrees Fahrenheit. It has approximately two-thirds of the thermal and electrical conductivity of copper. Aluminum has a high strength to weight ratio and is resistant to tarnishing and corrosion. Aluminum is an extremely versatile material, it may be cast or wrought, it is available in a wide range of alloys and tempers, and it accepts many types of surface finishes, including anodizing. Aluminum is easy to machine, solder and weld.
A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.
