Aluminum Fin Stock Strip For Heat Exchanger

As a sales representative at Haomei Aluminum with 20 years of experience in aluminum processing and export, I have handled hundreds of orders for heat exchanger aluminum fin strips. Over 90% of these are used in air conditioning heat exchange systems for residential, commercial, and automotive applications, serving renowned air conditioning unit manufacturers and supporting companies in Europe, America, and Southeast Asia. Unlike homogeneous products on the market, our aluminum fin stock strips, specifically customized for air conditioning heat exchange scenarios, embody our relentless pursuit of "high-efficiency heat exchange, energy saving, cost control, and durability" in every detail, from material composition to manufacturing processes and specifications. This is the core reason why we have long been a stable supplier to over 30 well-known global air conditioning equipment manufacturers.

In terms of technology and specifications, we adhere to the principle of "precise adaptation to air conditioning heat exchange," rejecting one-size-fits-all standardized production. All specifications can be customized according to air conditioning unit types (wall-mounted, floor-standing, and central air conditioning units). In terms of alloys, the main material adopts a customized 3003/3004 aluminum alloy strip (a special grade for air conditioner fins). The core components are strictly controlled as Si: 1.5~3.0wt%, Mn: 1.0~1.82wt%, Zn: 1.5~2.0wt%, with trace amounts of Sm elements to improve corrosion resistance. The ratio of Zn to Cu is ensured to meet 0.6wt%≤Zn-4*Cu≤1.2wt%.

Core specifications of aluminum fin stock strip can be flexibly customized: thickness 0.05~0.3mm (common for air conditioner fins: 0.08~0.12mm), tolerance ≤±0.005mm. Width 20~1200mm, tolerance ≤±0.1mm, can be precisely cut according to the size of the air conditioner heat exchanger coil. Surface finishes include smooth, hydrophilic coating, and anti-corrosion coating, suitable for different air conditioning application scenarios (e.g., anti-corrosion hydrophilic coating is preferred in humid areas).

In terms of manufacturing process, we adopt a secondary full recrystallization annealing process, with the annealing temperature precisely controlled between 270~500℃, resulting in an average grain size ≥600μm on the fin surface and a stable thermal conductivity of over 200W/(m·K), improving heat exchange efficiency by 15%~20% compared to ordinary aluminum fins; the surface is treated with a special hydrophilic coating, improving drainage performance by 30% and reducing frost by 40%, significantly reducing equipment maintenance costs.

As a company with both manufacturing and export capabilities, our advantages extend beyond the heat exchanger aluminum strip products themselves. From order confirmation to delivery, we provide dedicated one-on-one service throughout the entire process. We customize testing reports according to the regional standards of overseas clients (such as EU RoHS and US ASTM), and our sea freight delivery time is consistently 25-35 days. We also support small-batch trial orders to reduce client cooperation risks. Compared to our competitors, our products possess both military-grade precision engineering quality and extremely high cost-effectiveness, truly achieving "no compromise on quality, and more controllable costs."

Having cultivated the industry for many years, we deeply understand the core requirements of the heat exchanger industry for aluminum fin stock strips—high efficiency, durability, and strong adaptability. Haomei Aluminum always puts customer needs at the core, continuously optimizing product technology and improving its service system. If you are looking for high-quality, cost-effective aluminum fin strip for heat exchangers, feel free to contact us. We will use our professional products and services to become a reliable partner in your global supply chain and jointly promote the upgrading of the heat exchange industry.
