Hemaokang Steel (Shandong) Co., Ltd. is proud to present our premium 1100 H14 Aluminum Tube in 1" OD x 0.049" Wall Soft Temper Coil, engineered specifically for high-performance heat exchanger applications. With an annual export value exceeding US$50 million and a dedicated team of 51-100 professionals, we ensure consistent quality and reliable supply. This tube combines excellent thermal conductivity, corrosion resistance, and formability, making it the ideal choice for HVAC, refrigeration, and industrial cooling systems.
Our 1100 aluminum alloy, in H14 temper, offers a balanced combination of strength and ductility. The soft temper coil format allows for easy bending, coiling, and installation, reducing fabrication time and waste. Each coil is produced under strict ISO9001 quality management, ensuring dimensional accuracy and surface integrity. Below, we detail the key specifications and benefits that set this product apart.
- Alloy 1100: Commercially pure aluminum (99.0% min) with superior thermal conductivity (approx. 222 W/m·K) and excellent corrosion resistance, ideal for heat exchanger tubes.
- H14 Temper: Strain-hardened to a quarter-hard condition, providing moderate strength while retaining good formability for coiling and bending.
- Soft Temper Coil: Annealed to a soft condition, allowing easy unwinding, cutting, and shaping without cracking or spring-back.
- Precise Dimensions: 1" outer diameter (25.4 mm) with 0.049" wall thickness (1.2446 mm), manufactured to tight tolerances (±0.005" OD, ±0.003" wall).
- Surface Quality: Mill finish, free of burrs, scratches, and oxidation, ensuring efficient heat transfer and long service life.
- Customizable Lengths: Available in continuous coils up to 100 feet per coil, or cut-to-length pieces as required.
- Wide Application: Ideal for shell-and-tube heat exchangers, evaporators, condensers, radiators, and intercoolers.
- Eco-Friendly: 100% recyclable aluminum, supporting sustainable manufacturing.

The soft temper coil format is a significant advantage for heat exchanger manufacturers. Unlike straight tubes that require multiple joints, our coil tube can be continuously formed into serpentine or helical shapes, minimizing weld points and reducing the risk of leakage. This design also improves heat transfer efficiency by allowing longer uninterrupted flow paths.
Our 1100 H14 tube is compatible with standard brazing and welding processes, including TIG, MIG, and furnace brazing. The material's high purity ensures reliable joint strength and consistent performance under thermal cycling. Additionally, the smooth interior surface reduces pressure drop and fouling, extending maintenance intervals.
For customers requiring specific diameters or wall thicknesses, we offer custom sizes within our production capabilities. Our team of engineers can assist in selecting the optimal alloy and temper for your specific heat exchanger design, whether it's for air conditioning, automotive cooling, or industrial process heat recovery.
Hemaokang Steel (Shandong) Co., Ltd. was established in 2025 but rapidly grew to serve markets across North America, South America, Europe, Africa, Oceania, and Asia. With an annual export value of US$50 million to US$100 million, we have built a reputation for delivering high-quality aluminum products on time. Our ISO9001 certification guarantees that every production batch undergoes rigorous dimensional, mechanical, and surface inspection. We also offer third-party inspection reports upon request.
We understand that heat exchanger components must meet strict performance standards. That's why our aluminum tubes are tested for burst pressure, flattening, and flaring to ensure they withstand operational stresses. The soft temper coil is particularly suitable for tight-radius bends, with a minimum bend radius of 2x OD (2 inches) without wrinkling. This flexibility allows for compact heat exchanger designs, saving space and material costs.
By choosing our 1100 H14 aluminum tube, you benefit from:
- Reduced fabrication time – coil format eliminates the need for multiple tube joints.
- Lower total cost – less waste, fewer fittings, and faster installation.
- Enhanced thermal performance – high conductivity means smaller heat exchanger surface area for the same duty.
- Long-term reliability – excellent corrosion resistance extends equipment life.
- Global supply chain – we export to 15+ regions, with flexible logistics options.
We invite you to contact our sales team for a quotation or technical consultation. Whether you need a small sample coil for prototyping or a full container load for mass production, Hemaokang Steel is your trusted partner. Let us help you optimize your heat exchanger design with premium aluminum tube that performs.
Frequently Asked Questions
-
Q: What is the difference between 1100 H14 and 1100 O temper?
A: 1100 O temper is fully annealed (softest), while H14 is strain-hardened to a quarter-hard condition. H14 offers higher strength (110-145 MPa vs ~70 MPa for O temper) while still being formable. For heat exchanger coils that need to hold shape after bending, H14 is preferred. -
Q: Can this tube be used for high-pressure applications?
A: The tube is designed for typical heat exchanger pressures (up to 150 psi depending on temperature and configuration). For higher pressures, we recommend consulting our engineering team to evaluate wall thickness and temper selection. -
Q: Is the coil suitable for automated bending machines?
A: Yes, the soft temper coil is specifically designed for automated coil-fed benders. The material has consistent mechanical properties and excellent bendability without cracking. We can supply coils with inner diameters to match your machine's mandrel. -
Q: What surface treatments are available?
A: Standard product is mill finish. For additional corrosion protection, we can supply with clear anodizing, oil coating, or plastic end caps. Custom finishes are available upon request. -
Q: How long is the delivery lead time?
A: For standard sizes (1" OD x 0.049" wall), lead time is typically 15-20 working days after order confirmation. For custom dimensions, please allow 25-30 working days. We maintain a stock of 50 tons of 1100 alloy coils for quick dispatch. -
Q: Does the tube meet any international standards?
A: Our production follows ASTM B210 and ASTM B241 standards for seamless aluminum tube. We also comply with ISO9001 quality management system. Certificates of compliance can be provided with each shipment. -
Q: Can I get a sample before placing a bulk order?
A: Absolutely. We offer free sample coils (up to 5 meters) for qualified customers. Shipping cost is negotiable. Simply contact us with your project details and we will arrange a sample. -
Q: What is the minimum order quantity (MOQ)?
A: For standard coils, MOQ is 200 kg (approx. 1 coil of 100 ft). For custom sizes, MOQ is 500 kg. We are flexible for trial orders.
Contact Hemaokang Steel (Shandong) Co., Ltd. today for a customized solution. With our extensive export experience and ISO9001 certified production, your heat exchanger project is in capable hands.
