Is tensile strength of cable ties important? Cable ties are everywhere in both our work and daily lives. You might have used them to organize computer cables, or seen workers use them to secure heavy materials at construction sites. Different tasks and environments demand different strengths of cable ties. That’s why the tensile strength of cable ties is crucial for ensuring safety and efficiency.
What is Tensile Strength?
The tensile strength, of a cable tie, is one of the key indicators of its mechanical properties, determined by the material used. It measures the maximum stress that the material can withstand before it breaks or fails. Imagine holding a rope by its ends and gradually pulling it apart. When the force you apply exceeds the rope’s maximum threshold, it will snap. The force it withstands just before breaking is what we call its tensile strength.
Tensile Strength of Cable Ties
According to the industry standard in China for polyamide cable ties, QB/T4494-2013, the tensile strength standards for nylon cable ties are as follows:
| Width/mm | Tension/N |
| 1.0<W≤2.0 | ≥50 |
| 2.0<W≤3.0 | ≥80 |
| 3.0<W≤4.0 | ≥130 |
| 4.0<W≤5.0 | ≥180 |
| 5.0<W≤6.0 | ≥220 |
| 6.0<W≤7.0 | ≥360 |
| 7.0<W≤8.0 | ≥450 |
| 8.0<W≤9.0 | ≥530 |
| 9.0<W≤10.0 | ≥800 |
| 10.0<W≤11.0 | ≥890 |
| 11.0<W≤12.0 | ≥950 |
| 12.0<W≤13.0 | ≥1050 |
Tensile Strength of Stainless Steel Cable Ties
The tensile strength and testing methods for stainless steel cable ties are detailed in the article “Test the Tensile Strength of Metal Zip Ties in 3 Effective Steps“
| Material | Width(mm) | Thickness(mm) | (kg) |
| SS 304 | 4.6 | 0.25 | Over 100kg |
| SS 304 | 7.9 | 0.25 | Over 200kg |
Is the Tensile Strength of Cable Ties Important?
The tensile strength of cable ties is extremely important, just as we would not use a 2.5mm wide nylon cable tie to secure heavy-duty cables. Choosing cable ties with the right tensile strength is crucial for ensuring safety and durability.
- Safety: For components such as bridges, buildings, and aircraft, the materials used must be able to withstand the forces of normal operation as well as extreme conditions like strong winds, earthquakes, or heavy loads. This is crucial for safety.
- Durability: Tensile strength affects the durability and lifespan of a product. Materials with high tensile strength are less likely to deform or break under stress, making them more durable.
As shown in the diagram, wider cable ties not only provide a larger contact area, reducing damage to the cables but also withstand greater forces, preventing loosening or breaking under heavy loads.
