Flexibility and Durability
Stranded resistance alloys offer several significant benefits in various applications. As with all stranded connectors, using a stranded construction enhances the wire’s flexibility, allowing it to be easily shaped and formed. However, manufacturing stranded cables from resistance alloys offers additional benefits, particularly in applications where resistance to electrical current is needed to generate heat.
Electrical Resistance
Resistance alloys are advanced materials specifically engineered to offer high electrical resistance, making them ideal for various applications that require controlled electrical properties. When used for cables, this property ensures efficient transmission of electrical currents through the stranded conductor, minimising power loss during transmission. While these alloys are not typically used for standard electrical wiring due to their lower electrical conductivity, they are essential in manufacturing heating elements and in applications requiring precise temperature control.
Heat Resistance at Elevated Operating Temperatures
Stranded resistance wire possess excellent heat resistance, allowing them to operate in high-temperature environments without significant degradation in performance.
Mechanical Strength and Corrosion Resistance
Furthermore, stranded wire manufactured from resistance alloys exhibit excellent corrosion resistance and high mechanical strength. This protects the conductor from environmental factors that may cause degradation over time and enables it to withstand the mechanical stresses experienced during installation, operation, and handling. The end result is increased the longevity and reliability.

When it comes to wire products, it’s important to understand the differences between stranded wire, wire strand, and wire rope. While they may sound similar, each has its own unique characteristics and applications.
Stranded Wire
Stranded wire is composed of multiple small-gauge wires twisted together in a specific arrangement. By intertwining these individual wires, stranded wire offers increased flexibility, durability, and strength compared to solid wire. It is commonly used in applications that require flexibility and resistance to fatigue, such as electrical wiring, automotive harnesses, and electronic devices.
Wire Strand
A wire strand consists of several strands of wire grouped together. These strands are typically composed of multiple individual wires twisted together to form a larger unit. Wire strands are employed for applications that require higher strength and load-bearing capabilities. They are commonly found in structural projects, reinforcing concrete, suspension bridge cables, and guy wires for towers and antenna structures.
Wire Rope
Wire rope is a more robust and heavy-duty construction compared to stranded wire and wire strand. It is created by combining multiple wire strands and twisting them together in a helical pattern around a central core. This configuration provides superior strength, durability, and resistance to breaking and bending. Wire ropes are extensively used in industries such as construction, mining, maritime, and oil and gas for applications like cranes, elevators, winches, and rigging operations.
Wire stranding and bunching are specialised processes that combine multiple strands of wire together to increase flexibility and fatigue resistance in comparison to single strand wire.
Benefits of Stranded wire vs Single Strand wire:
The benefits of using stranded wire over single strand has made it essential for applications across several industries ranging from automotive, aerospace, electronics, medical devices and more.
Stranding and bunching involve twisting together multiple wire strands to create a single, larger conductor. Stranding is typically used to increase flexibility and fatigue resistance, while bunching is often employed for applications requiring compact wire with high conductivity. These processes are essential in producing cables and wires for various applications across industries such as electronics, automotive, aerospace, and more.
