1xxx/3xxxx/8xxx Материалы алюминиевых ребер для теплообменника

Как профессионал материал алюминиевых ребер производитель, Haomei Aluminum has established a complete product matrix covering the 1xxx series, 3xxx series, and 8xxx series alloy systems. Leveraging independent casting and rolling, precision cold rolling, and surface treatment full-chain production capacity, Haomei provides multi-specification, high-performance aluminum fin material solutions for global air conditioning, heat pump, and industrial heat exchange equipment manufacturers. All products strictly adhere to ASTM B209 and EN 546 international material standards, with thicknesses covering the full range of 0.08mm–0.20mm and widths customizable from 100mm–1300mm. Various surface treatment options are available, including plain foil, hydrophilic, hydrophobic, and anti-corrosion coatings. These aluminum fin stock products are directly compatible with various high-speed fin stamping production lines, and their batch delivery stability and specification adaptability have been verified by hundreds of customers worldwide.

The 1xxx series pure aluminum fin stock, featuring superior thermal conductivity, are our core high-end products for high-precision heat exchange applications. This series uses 1050, 1060 and 1100 aluminum alloys as the base material, with strictly controlled aluminum content ≥99.6% and impurities such as iron and silicon kept to extremely low levels. The finished product’s room temperature thermal conductivity consistently reaches over 235 ж/(м·К). We refine the grain structure through a multi-pass homogenization annealing process, ensuring the elongation of the O-state product is consistently controlled at 30%–35%, exhibiting excellent shallow drawing and flanging performance. The finished product thickness tolerance is ≤±1.5μm, and the plate flatness is controlled within 5I, suitable for the precision stamping requirements of precision micro heat exchangers. 1xxx series aluminum fin stock product is mainly exported to the high-end refrigeration markets in Europe and North America, supporting precision computer room air conditioning, medical refrigeration equipment, and low-temperature heat exchange units, and has a long history of stable repeat purchases from customers.

The 3xxx series aluminum-manganese alloy fin stock are corrosion-resistant and reinforced products developed for harsh operating conditions, with the main model being the 3003 алюминиевый сплав. The solid solution strengthening effect of manganese gives the material a tensile strength of 130–160 MPa, significantly superior creep and collapse resistance compared to pure aluminum substrates, allowing for thinner fin designs and higher fin density. More importantly, the oxide film on the surface of the 3003 aluminum alloy is denser and more uniform. Our chromium-free passivation process can extend the neutral salt spray tolerance time to over 720 часы, effectively resisting corrosion from coastal salt spray and industrial exhaust gases. 3xxx series aluminum fin stock products is primarily supplied to commercial air conditioning and heat pump manufacturers in the Middle East and Southeast Asia coastal regions. Customer tests have shown that the service life of the outdoor unit fins can be extended by more than 40% compared to ordinary pure aluminum fins, with a significantly reduced after-sales failure rate.

The 8xxx series aluminum-iron-silicon alloy fin stock are our main general-purpose product with the largest production scale and widest application. The core model is the 8011 алюминиевый сплав. By precisely controlling the iron and silicon element ratios and annealing process, наш 8011 aluminum fin stock achieve an excellent balance between thermal conductivity, strength, and formability: thermal conductivity is consistently above 220 ж/(м·К), tensile strength is controlled within the 120–160 MPa range, the grain structure is fine and uniform, the pass rate for louver stamping and flanging is consistently above 99.5%, and the burr height is ≤0.01 mm. Thanks to its balanced performance and economies of scale, в 8011 серии кондиционер алюминиевая фольга has become the mainstream choice for residential air conditioners, small and medium-sized commercial units, and automotive air conditioners, currently accounting for over 60% of our total fin product exports. We supply dozens of air conditioner manufacturers in Southeast Asia, South America, and Africa, with a stable monthly supply exceeding 1,000 тонны.

All aluminum fin material products rely on our closed-loop quality control system to ensure consistent delivery. Each batch of products undergoes mandatory inspections before leaving the factory, including chemical composition, механические свойства, dimensional deviation, and surface quality. Complete material certification documents are provided for full traceability. The coils use 76mm/152mm international standard cores, with single roll lengths ranging from 8000 к 10000 метры, effectively reducing customer downtime for roll changes. Leveraging over ten years of experience exporting aluminum fin stock, we can quickly respond to customers’ needs for customized specifications, coating selection, and technical support in different regions, providing heat exchange equipment manufacturers with a stable and reliable one-stop fin material supply service.
