1+6+12
Very common, good softness
Battery leads, heaters, brush wires, etc.
37
1+6+12+18
High flexibility and uniform current carrying capacity
Instrument cables, welding cables
61
1+6+12+18+24
Higher flexibility and conductivity
Highly flexible connection, industrial high-end cable
Design considerations for selecting the number of shares
Considerations
Explanation
Softness
The more strands and the thinner the monofilament, the softer it is.
Mechanical strength
Fewer strands, larger wire diameter, higher tensile strength, but reduced softness
Current carrying
The total cross-sectional area determines the main conductivity, and the number of strands affects heat dissipation and skin effect.
Manufacturing Cost
More strands means increased manufacturing complexity and cost
Why is 19 strands commonly used?
Stable structure: 1+6+12 is a typical three-layer concentric twist, geometrically balanced
Considering both cost and flexibility: softer than 7-strand and cheaper than 37-strand
Commonly used in high conductive materials such as Nickel wire, Copper wire, Nichrome wire, FeCrAl wire, etc.
We can do more, please let us know your requirements.
Each spool contains one continuous length of wire. In most cases we can split your order into coils of lower weight (please ask for specifics).
Each spool is tested for alloy material identification. Mechanical testing is performed on each spool or as per our sampling plan, depending on the number of spools.
All spools are labeled and packed in appropriate cartons or wooden boxes depending on the chosen mode of transport.
