Import Aluminum Extruded Heat Sink — Buy in wholesale FOB from Supplier in China

This aluminum extruded heat sink from Dongguan Baoyue Electronic Hardware Technology Co. Ltd. is manufactured from 6000 series non-alloy aluminum with T3-T8 temper, a material grade widely recognised for its balance of thermal conductivity and extrudability in electronics cooling applications. The T-profile geometry optimises heat dissipation surface area while maintaining structural rigidity under thermal cycling, with a stated tolerance of 1% on critical dimensions. The product carries the BAOYUE brand designation and model number BY57, and is offered with customised sizing and colour options alongside OEM/ODM service capabilities.

The base material, 6000 series aluminum in T3-T8 temper, delivers thermal conductivity typical of this alloy family, generally ranging 160-200 W/(m·K) depending on exact temper and processing history. The extrusion process allows complex cross-sectional profiles such as the T-profile specified, with CNC and skiving secondary operations available for fin refinement and dimensional accuracy. Anodising is offered as a surface treatment, providing a conversion coating that improves corrosion resistance and emissivity, both relevant to long-term thermal performance. The supplier also lists bending, decoiling, welding, punching, and cutting as processing services, indicating capability to deliver semi-finished or fully fabricated thermal management components.

Primary applications span electronic appliances, industrial machinery, and power electronics, where the heat sink functions as a passive thermal interface between heat-generating semiconductors and ambient air. Buyers include OEMs in consumer electronics, industrial control systems, telecommunications equipment, and LED lighting manufacturing. The stated supply capacity of 200,000 pieces per month suggests volume scalability, though buyers should confirm current lead times and minimum order quantities directly with the supplier. Payment terms are listed as T/T only, and delivery time is quoted at 15-21 days, but these should be verified in current quotations as market conditions may affect actual availability.

Dongguan Baoyue Electronic Hardware Technology Co. Ltd. is located at Unit 1, Building 3, No. 1257, Chang'an Section, Tai'an Road, Changan Town, Dongguan, Guangdong, postal code 523846, China. The Changan Town area of Dongguan is a recognised cluster for precision metalworking and electronics hardware manufacturing, with established supply chains for aluminum extrusion and CNC machining services. The supplier carries a 'harbor' trust tier designation, and lists a response rate of 0.00% with zero average response hours, which indicates no response data is currently recorded for this account. Buyers should note that this absence of response metrics does not indicate verification status or trading history, and direct communication is essential to assess current operational capacity.

The company profile does not disclose founding date, employee count, revenue, or specific client references, so no such details can be stated. What the listing does communicate is a focus on custom manufacturing services, OEM/ODM capability, and a stated monthly production capacity of 200,000 pieces. The product range centres on aluminum extruded thermal management components with secondary machining and finishing. Buyers evaluating this supplier should request factory audit reports, quality management system documentation, and sample evaluation to supplement the limited verification signals available through the listing profile.
