5052 / 5154 / 5154A – High Strength, Lightweight & Corrosion Resistant
MC Cable High Strength Factory Supply
Get Instant QuoteAluminum strip is used to form a helically interlocked armor layer in cables, providing mechanical protection, flexibility, and corrosion resistance.
Our 5xxx series aluminum alloy strips are specifically designed for high-speed interlocking armoring lines. Compared to standard 1xxx series alloys, these strips contain higher magnesium content, offering superior structural integrity and fatigue resistance for MC cables and power cables.
We utilize precision slitting technology to ensure width tolerances within ±0.02 mm, preventing machine jamming and ensuring a smooth interlocking process.

Our Interlocking Aluminum Alloy Strip for Armored Cable undergoes strict quality control in accordance with international industrial standards for cable armoring materials. Each production batch is fully inspected to ensure consistent mechanical performance and reliable forming behavior during high-speed interlocking processes.
Quality testing includes tensile strength testing, elongation measurement, and comprehensive surface inspection to guarantee defect-free, burr-free, and uniform strip quality. This ensures stable performance in MC cables, power cables, and industrial armoured cable systems.
Every coil of aluminum strip is fully traceable, from raw material smelting to final slitting and packaging, supporting full quality transparency and long-term reliability for global cable manufacturers.
What are the advantages of 5154A for cable armoring applications?
5154A offers an optimal balance between flexibility and tensile strength, ensuring the armor layer does not crack during tight-radius bending while maintaining high compressive strength and long-term mechanical stability.
Is the surface free from oil, contamination, and burrs?
Yes. All aluminum strips undergo professional degreasing and strict edge trimming processes to ensure a clean silver surface, burr-free edges, safe handling, and stable forming performance in high-speed interlocking production lines.
Why choose aluminum alloy strip instead of traditional steel strip for interlocking armor?
Aluminum alloy strip reduces weight by approximately 50% and is fully non-magnetic, eliminating eddy current losses. It is especially suitable for AC power cables and submarine composite cables, while also offering better corrosion resistance than galvanized steel and lower lifecycle cost.
Is 5052 aluminum alloy suitable for marine environments?
5052 provides good resistance to seawater corrosion. However, for long-term full immersion or high-flow marine conditions, 5154A is recommended due to its higher magnesium content and superior pitting corrosion resistance.
How to select temper condition for interlocking armor forming?
For complex S-type interlocking structures and high-speed forming lines, O temper is recommended due to maximum elongation. For standard medium and low-voltage cables, H22/H24 temper provides a balance between strength and formability. For heavy-duty protection armor, H26 temper is preferred for higher mechanical resistance.
How does thickness tolerance affect interlocking armor quality?
Interlocking forming requires extremely consistent thickness. A deviation beyond ±0.03mm may cause loose locking or unstable tension. Our strips are controlled within ±0.01mm with no edge wave, ensuring airtight armor structure and strong side pressure resistance.
