Cable / Wire Rope
Cable is the generic term that refers to constructions of wire rope that fall into the category of aircraft cable. These constructions include 7 x 7 (seven groups of 1 x 7 strand) and 7 x 19 (seven groups of 1 x 19 strand) respectively. "Aircraft cable" ranges in size from 1/32" to 3/8".
WIRE ROPE is technically the correct term for groups of strand wrapped in a uniform helix around a core. Sizes over 3/8" are not considered aircraft cable, they are wire rope. The constructions included in wire rope are numerous, but the most common are 6 x 19 and 6 x 37 class wire ropes. These descriptions of the construction fail to include the core as a part of the primary number. Part of the reason for this is that the composition and the construction of the cores in these wire ropes is so numerous, that it is necessary to call out the outer construction of the wire rope and then describe the core. Such as 6 x 19 fiber core, or 6 x 37 IWRC (Independent Wire Rope Core). The terms CABLE and WIRE ROPE are synonymous for all intents and purposes.
CORE
The core can be a variety of things, including: Strand in many constructions or even a cable or wire rope. The core can also be of a composition other than metal, such as polypropylene rope. Whatever the construction or the composition of the core, it is the center member of the cable or wire rope.
COMPOSITION
CARBON STEEL WIRE is available in different grades, sometimes referred to as Plow Steel, Improved Plow Steel, or even Extra Improved Plow Steel. Wire rope manufactured from uncoated wire is commonly referred to as Bright. Bright wire rope is available in sizes 1/4 inch and over.
GALVANIZED carbon steel wire is frequently used to manufacture wire rope. Galvanized wire rope provides good corrosion protection in mild environments. In smaller sizes (less than 1/4 inch) it is almost automatically used when stainless steel is not specified.
