AA1050 H24 0.5MM Prepainted Aluminium Coil for Small Heat Sink

The AA1050 H24 0.5MM Prepainted Aluminium Coil is a specialized material engineered for the production of small heat sinks, which play a critical role in heat dissipation for compact electronic and electrical devices. Crafted from AA1050 aluminum alloy (containing 99.5% pure aluminum), this coil undergoes the H24 tempering process—characterized by strain hardening followed by partial annealing—to strike an optimal balance between thermal conductivity, mechanical stability, and formability. With a ultra-thin yet robust 0.5mm thickness and a high-performance prepainted coating, it addresses the dual demands of efficient heat transfer and long-term protection, making it an indispensable choice for small heat sink manufacturers.

Product Parameters

Application Scenarios

• Consumer Electronics: Heat sinks for smartphones, tablets, laptops (e.g., CPU/GPU auxiliary heat sinks), wireless chargers, and portable power banks. Its thin 0.5mm profile fits seamlessly into miniaturized device designs while ensuring effective heat management.
• Home Appliances: Small heat sinks in microwave ovens (control panel components), mini air conditioners (circuit board cooling), and electric kettles (temperature controller heat dissipation). The corrosion-resistant coating withstands mild heat and moisture in household environments.
• Automotive Electronics: Compact heat sinks for in-car infotainment systems, GPS modules, LED headlights (driver circuit cooling), and sensor components. Its lightweight nature and thermal performance support automotive efficiency goals.
• Industrial & Medical Devices: Heat sinks for small industrial sensors, portable medical equipment (e.g., blood glucose monitors, thermometers), and LED lighting fixtures (driver heat dissipation). The non-toxic, pure aluminum composition meets strict safety standards for medical and industrial use.
• Renewable Energy Devices: Small heat sinks in solar charge controllers, mini wind turbine electronics, and portable solar panels (voltage regulator cooling). The weather-resistant coating ensures durability in outdoor or semi-outdoor settings.
