7*0.25 NiCr6015 Wire Cable Stable Resistivity Strand Rope
1. Nichrome Alloy
Nichrome wire is made of a non-magnetic alloy composed primarily of
nickel, chromium, and iron. Nichrome is characterized by its high
resistivity and good oxidation resistance. Nichrome wire also has
good ductility after use and excellent weldability.
The number that comes after the Nichrome wire type indicates the
percentage of nickel in the alloy. For example, "Nichrome 60" has
approximately 60% Nickel in its composition.
Applications for Nichrome wire include heating elements of hair
dryers, heat sealers, and ceramic support in kilns.
2. NiCr 60
It is ideal for use as heating elements in household utilities and
in moderate heat, high humidity environments.
Applications: Metal sheathed tubular elements used in, for example,
hot plates, grills, toaster ovens and storage heaters. The alloy is
also used for suspended coils in air heaters in clothes dryers, fan
heaters, hand dryers.

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.
