2. Production & Manufacturing Process
Our aluminum strip & foil is manufactured under strict quality control to ensure consistent performance for industrial use:
Raw Material SourcingWe use high-grade primary aluminum ingots (≥99.7% purity) to eliminate impurities and guarantee the required conductivity and formability.
Melting & Continuous CastingThe aluminum is melted in a controlled atmosphere furnace and cast into uniform billets, ensuring consistent chemical composition across the material.
Hot RollingThe billets are heated and passed through multi-pass hot rolling mills to form continuous aluminum strips, refining the grain structure and improving mechanical properties.
Cold Rolling & AnnealingThe hot-rolled strips are further reduced in thickness via cold rolling to achieve precise dimensional tolerances. Intermediate annealing is performed to restore ductility and relieve internal stress, ensuring the material is suitable for subsequent forming and winding.
High-Speed Trimming & SlittingAs the inventor of high-speed trimming equipment and technology, we process the aluminum strips with precision slitting lines. This ensures the edges of the aluminum strip/foil are smooth, clean, and completely burr-free-critical for preventing electrical arcing and ensuring safety in high-voltage applications.
Surface Treatment & FinishingOptional surface treatments, such as degreasing, cleaning, or anti-tarnish coating, are applied to enhance corrosion resistance and improve adhesion for subsequent processes like lamination or soldering.
Quality Testing & InspectionEvery batch undergoes strict quality checks, including:
Purity analysis
Conductivity testing
Dimensional tolerance verification
Edge quality inspection
Surface finish evaluation

6. Frequently Asked Questions (FAQ)
Q1: What is the difference between 1050 and 1060 aluminum strip?
A: Both are pure aluminum grades with similar properties. 1050 has a minimum aluminum content of 99.5%, while 1060 has a minimum of 99.6%, offering slightly higher purity and conductivity. Both grades are suitable for electrical applications like transformers and cables.
Q2: Why choose aluminum strip over copper for transformer applications?
A: Aluminum is significantly lighter and more cost-effective than copper, while still offering sufficient conductivity (61% IACS) for many power applications. It is ideal for large-scale projects where weight and cost reduction are priorities, without compromising performance.
Q3: Why are burr-free edges important for aluminum strip in power equipment?
A: Burrs or rough edges can cause electrical field concentration, leading to partial discharge, arcing, and premature insulation failure in high-voltage environments. Our high-speed trimming technology eliminates this risk, ensuring stable, safe operation in transformers, reactors, and cables.
Q4: What size ranges do you offer?
A: Standard thickness: 0.1–3mm; standard width: 15–1650mm. We also provide custom slitting and cut-to-length services to match your specific application requirements.
Q5: Can you provide custom processing for specialized power applications?
A: Yes. We offer precision slitting, surface treatments (anti-tarnish, passivation), and custom packaging to meet the unique requirements of transformers, reactors, and power cable manufacturers.
Q6: How do you prevent oxidation and damage during shipping for export orders?
A: We use multi-layer protection, including anti-rust paper, VCI film, and fumigated wooden pallets/crates, to protect aluminum strip from moisture, oxidation, and mechanical damage during long sea voyages.
Q7: What is your lead time for bulk orders?
A: Standard bulk orders take 2–3 weeks. Custom orders with special processing or sizes may require additional time. Contact us with your specifications for a detailed quote and delivery schedule.
Q8: Do you offer sample orders?
A: Yes. We provide free samples for quality verification; customers only need to cover the shipping cost.
