Flexible Fire-Resistant Cables
Excellent wrapping performance and welding consistency, suitable for high-speed continuous production lines.
Mineral Insulated Cable (MI Cable)
Provides excellent metallic sheath sealing performance, ensuring fire resistance and pressure resistance of the cable.
Corrugation Welding Process
High elongation design ensures that the aluminum layer does not thin or crack during the corrugation process.
1060 Aluminum Alloy
99.6% purity, excellent electrical conductivity (~55% IACS), strong corrosion resistance, very suitable for flexible fire-resistant cable sheaths requiring high ductility.
1050 Aluminum Alloy
A cost-effective alternative with 99.5% purity, good formability and weldability, widely used in mineral insulated cable production with stable argon arc welding performance.
3003 Aluminum (Al-Mn)
Higher mechanical strength than pure aluminum and excellent corrosion resistance. It is ideal for corrugated sheaths requiring extra strength without compromising welding integrity.
Why is aluminum strip used for argon arc welding?
Aluminum strip provides a stable welding arc, lightweight structure, and excellent corrosion resistance for cable sheath systems.
Which alloy is best for argon arc welding applications?
1050 and 1060 aluminum alloys offer the best weldability, while 3003 is preferred when higher mechanical strength is required.
Can coil sizes be customized?
Yes. Inner diameter 200–500 mm and outer diameter 1000–2000 mm can be customized according to production equipment requirements.
Is it suitable for mineral insulated cable (MI cable) production?
Yes, it is widely used in mineral insulated cable manufacturing lines.
What is the difference between 1060 and 3003 aluminum for argon arc welding sheaths?
1060 aluminum offers the best ductility and conductivity, making it ideal for thin-walled flexible cables. 3003 provides higher strength and is suitable for heavy-duty corrugated sheaths requiring impact resistance. Both perform well in O-temper condition.
Why is O-temper (annealed condition) critical for aluminum strip welding?
O-temper aluminum is in its softest state, allowing easy forming into tubes without springback or cracking. It ensures uniform weld penetration and minimizes heat-affected zone defects.
Can you produce non-standard inner/outer coil diameters (e.g. ID 350 mm, OD 1500 mm)?
Yes. We adjust coil winding dimensions based on your pay-off equipment. Minimum inner diameter is 200 mm and maximum outer diameter is 2000 mm. All intermediate sizes can be customized through our slitting and rewinding production line.
What surface oil level is suitable for argon arc welding?
We control residual oil content within ≤50 mg/m² to avoid porosity in weld seams. Degreasing treatment is available upon request for critical welding applications.
How can I obtain samples or trial coils?
We provide sample strips (5–10 kg) and trial coils with competitive lead times. Please contact our sales team for customized trial arrangements.
