Shandong Sino Steel Co., Ltd. proudly presents our premium Aluminum Coil for Air Conditioning Fins – alloy 1100, 0.1 mm thickness, mill finish. As a manufacturer with a 10,000–30,000 m² factory and ISO9000/ISO19011:2000 certified management, we deliver coils that offer exceptional formability, corrosion resistance, and thermal conductivity for high-efficiency AC fin production. Our product is trusted by clients across North America, South America, Europe, Southeast Asia, and the Middle East, ensuring consistent quality for demanding HVAC applications.
This aluminum coil is specifically engineered for the manufacturing of air conditioning condenser and evaporator fins. With a thickness of just 0.1 mm, it allows for precise fin spacing and optimized heat transfer. The mill finish surface provides a clean, uniform appearance that is ideal for subsequent louvering or slit-fin processes. Whether you need standard widths or customized dimensions, our flexible production capacity and experienced team can meet your exact requirements.
Key Features & Advantages:
- High Purity Alloy 1100: 99.0% minimum aluminum content, offering excellent ductility and workability for intricate fin patterns.
- Precision Thickness Control: ±0.005 mm tolerance ensures uniform fin height and consistent airflow resistance.
- Mill Finish Surface: Clean, oxide-free surface ready for direct use without additional cleaning – reduces production lead time.
- Superior Corrosion Resistance: Ideal for humid or coastal environments, prolonging the lifespan of AC units.
- Customizable Temper: Available in O (fully annealed) or H14 (half-hard) to match your specific forming and strength requirements.
- Efficient Packaging: Moisture-proof wrapping and sturdy wooden pallets protect coils during long-distance shipping from Qingdao, Tianjin, or Shanghai ports.

Frequently Asked Questions
-
Q: What is the typical temper for air conditioning fin coils?
A: The most common tempers are O (fully annealed) for maximum formability, and H14 (half-hard) for applications requiring slightly higher stiffness. We can supply either based on your forming process. -
Q: Can you provide coils with a width of exactly 600 mm?
A: Yes, we offer custom widths from 100 mm to 1200 mm. Minimum order quantity may apply for non-standard sizes – please discuss with our sales team. -
Q: How do you ensure the surface is free of oil stains?
A: Our mill finish process includes a final annealing step that burns off any residual rolling oil. The coil is then inspected for cleanliness before packaging. -
Q: What is the tolerance on thickness for 0.1 mm coils?
A: Standard tolerance is ±0.005 mm. For tighter tolerances (±0.003 mm), we can arrange special production – lead time may be extended by 3–5 days. -
Q: Do you offer samples before bulk order?
A: Absolutely. We provide free samples (A4 size or 1 kg coil piece) for customer evaluation. You only need to cover the shipping cost. -
Q: How long does shipping take to North America?
A: From Qingdao port, sea freight to US West Coast typically takes 15–20 days; to East Coast 25–30 days. We can also arrange air freight for urgent orders. -
Q: Is this coil suitable for high-speed louver fin machines?
A: Yes, our 1100-O temper coil is specifically designed for high-speed fin presses. The consistent thickness and elongation ensure minimal tool wear and fewer breaks. -
Q: Can you supply larger coils (e.g., 3000 kg per coil)?
A: Yes, we can produce coils up to 3000 kg net weight. Please confirm your handling equipment capability to avoid coil damage during loading.
