Wire rope with 6x7 fiber core standard construction, also called sash cord, is commonly used for sand lines, or for swabbing in drilling applications. Bronze material resists corrosion caused by brine, gases, and sulfite solutions. This material is non-magnetic, non-sparking, and has a smooth finish for ease of operation. 6x7 class fiber core has six strands of wire rope with three to fourteen wires in each strand, of which no more than nine are outside wires, and is formed helically around a fiber core. 6x7 fiber core is fatigue-resistant, and is a standard construction wire rope.
Wire rope, also called wire cable, is an assembly of wire strands formed helically around a central core. It is used for pulling, lifting, rigging, hoisting, and motion-control applications most commonly found in the manufacturing, marine, oil, mining, fiber-optics, aircraft, automotive accessory, and construction industries. A combination of characteristics including material, finish, construction, diameter, length, and breaking strength combines to give each rope its performance ability. Wire rope materials are selected for properties such as strength, elasticity, conductivity, and chemical- and weather-resistance. For strength purposes, most wire rope is made of bright (uncoated or bare) wire. However, it is also produced in a variety of finishes, such as polypropylene (PE), vinyl (PVC), or nylon. These coatings can increase overall durability and strength, and allow for specific use. The breaking strength for wire rope is the strength at which new wire rope will fail under a stationary load. Breaking strength is not considered safe working load (SWL) limit.
