19*0.57mm Ni60Cr15 Nickel Chromium Alloy Stranded Wire Multi-Strand Wire

Detailed Description of Stranded Wire:

Stranded wire is extremely versatile and employed in a number of industrial, commercial, and consumer applications. While some applications require solid conductor wires and cables, stranded wire is often preferred for its greater degree of flexibility.

Stranded cables and wires are used heavily in industries which require a great deal of lifting, support, and tension such as aerospace, automotive, communications, chemical, electronics, defense, security, and medical industries. To suit the needs of these industries and more, stranded rope is increasingly specialized. If uncertain, wire rope suppliers should be consulted in order to select the proper wire and avoid potentially costly and dangerous mechanical failures.

Stranded wires are identified by listing both the number of strands and the amount of wires per strand respectively as well as the lay and pitch of the rope. Identification codes can also extend to specifics such as core type, workload limit, and more, listed in abbreviated form.

The connections, fasteners, fittings, and other hardware attached to the stranded wire are also important as they offer differing degrees of wire versatility in terms of fray prevention and connectivity.

Number of strands

The more individual wire strands in a wire bundle, the more flexible, kink-resistant, break-resistant, and stronger the wire becomes. However, more strands increases manufacturing complexity and cost.

For geometrical reasons, the lowest number of strands usually seen is 7: one in the middle, with 6 surrounding it in close contact. The next level up is 19, which is another layer of 12 strands on top of the 7. After that the number varies, but 37 and 49 are common, then in the 70 to 100 range (the number is no longer exact). Even larger numbers than that are typically found only in very large cables.

For application where the wire moves, 19 is the lowest that should be used (7 should only be used in applications where the wire is placed and then does not move), and 49 is much better. For applications with constant repeated movement, such as assembly robots and headphone wires, 70 to 100 is mandatory.

For applications that need even more flexibility, even more strands are used (welding cables are the usual example, but also any application that needs to move wire in tight areas). One example is a 2/0 wire made from 5,292 strands of #36 gauge wire. The strands are organized by first creating a bundle of 7 strands. Then 7 of these bundles are put together into super bundles. Finally 108 super bundles are used to make the final cable. Each group of wires is wound in a helix so that when the wire is flexed, the part of a bundle that is stretched moves around the helix to a part that is compressed to allow the wire to have less stress.
