Import Aluminum Heat Sink — Buy in Bulk from Supplier in China

This aluminum heat sink is manufactured from 6000 series aluminum, a grade recognized for its balance of strength, thermal conductivity, and formability. The product is supplied in temper grades T3 through T8, with T6 being the most common for thermal applications due to its optimal combination of hardness and heat dissipation. The precision-engineered fin design increases surface area, which improves convective heat transfer in forced or passive cooling setups. The unit’s lightweight structure reduces mechanical load without compromising durability, making it suitable for integration into compact electronic assemblies.

Aluminum 6000 series alloys typically contain magnesium and silicon as primary alloying elements, offering good corrosion resistance and a typical thermal conductivity of 167 to 200 W/m·K. Standard fin heights range from 5 mm to 50 mm, with pitches between 1.5 mm and 5 mm for extruded profiles, though custom geometries are available. Surface treatments such as anodizing are typical for enhancing oxidation resistance and aesthetic finish, with black anodized coatings often used in high-end electronics for better emissivity.

Primary buyers include manufacturers of LED lighting systems, power electronics, and server cooling solutions, where thermal management is critical to component longevity. The heat sink is also used in automotive electronics and HVAC systems, where operating temperatures must remain within tight tolerances. For bulk orders, packaging is typically in cartons with foam inserts to prevent fin damage, and the product can be supplied in cut-to-length or pre-assembled configurations. Confirm MOQ, lead time, and incoterms directly with the supplier, as these are not specified in the listing.

Dongguan Baoyue Electronic Hardware Technology Co. Ltd. operates from Unit 1, Building 3, No. 1257, Chang'an Section, Tai'an Road, in Changan Town, Dongguan, Guangdong. The company is registered with a Harbor trust tier, indicating a baseline level of profile verification. Its focus is on industrial-grade thermal management components, including heat sinks designed for machinery manufacturing, aerospace, and electronic appliance sectors.

The supplier’s listing specifies no response rate or average response time, so buyers should expect to follow up directly for inquiries. The company does not provide details on factory scale, production capacity, or certifications in the profile, so these must be confirmed through direct communication. Orders are likely fulfilled from Dongguan, a hub for electronics hardware production, with logistics coordinated based on buyer requirements.
