How strong is 12 gauge wire?

Baling Wire Direct delivers the strongest, most reliable baling wire products to our customers.

The strength of baling wire is influenced by its gauge (thickness). There is a clear correlation between wire gauge and wire strength; thicker wires are stronger than thinner wires, all else being equal.

For example, a 12 gauge wire is thicker than a comparable 14 gauge wire, and as a result, will also be stronger.

Types of wire strength

While there are different aspects of wire strength, tensile strength is the most common metric to focus on:

  • Tensile strength measures the maximum stress that a wire can endure when being pulled or stretched before it breaks. Expressed in units of force per unit area—MPa (megapascals) or psi (pounds per square inch).
  • Load strength measures the pressure a wire can handle before failing. It is directly related to the wire's tensile strength and is measured in pounds (lbs).
  • Elongation is a wire's ability to plastically deform before breaking and is reported as a percentage. It indicates the ductility of the wire, with a higher elongation percentage meaning the wire can undergo more stretching.
  • Yield strength is the point of tension at which elongation begins. It is related to a wire's ability to stretch and maintain its integrity under stress.
  • Torsional strength is a measurement of a wire's ability to withstand twisting without breaking or deforming.

Understanding wire gauge

Wire gauge is a measurement that originates from the manufacturing process of drawing wires through a series of progressively smaller holes. The drawing process uses a draw plate, which is a tool with a series of conical or cylindrical holes that decrease in size.

As the wire passes through each hole, its diameter is reduced by a specific increment. This process is repeated until the desired diameter is achieved.

The primary system used in North America is American Wire Gauge (AWG), while the British Standard Wire Gauge (SWG) system is most commonly used in the United Kingdom and some other countries.

12 gauge wire strength specifications

Our baling wire is made with high-quality, American-made steel billets. Our meticulous manufacturing process exceeds industry standards for performance and reliability.

Here is a quick breakdown of the tensile and load strength specifications of our 12 gauge wire products.

If all other factors are the same, a lower-gauge wire will be stronger than a higher-gauge wire (e.g. an 11 gauge wire is stronger than a 12 gauge wire), given that diameter and gauge are inversely related.
