Buy & Import CNC Machining Aluminum Heat Sink from Hebei Xindongrui Alloy Material Technology co.,ltd - China Wholesale Supply

This CNC machined aluminum heat sink is fabricated from 6063 aluminum alloy in T3 to T8 temper, delivering thermal conductivity of 201 W/m·K typical for this grade, which is critical for dissipating heat from power electronics and LED assemblies. The flat-shaped profile is precision machined to achieve tight tolerances and smooth finishes, with a minimum thickness of 0.8 mm as stated in the listing. An anodized oxidation coating enhances corrosion resistance and surface hardness, making it suitable for harsh industrial environments.

The 6063 alloy is a medium-strength aluminum commonly used in heat sinks due to its excellent extrudability and thermal properties, with a typical yield strength of 145 MPa in T6 temper and elongation of 12%. The supplier confirms custom length options, allowing buyers to specify dimensions tailored to their PCB or enclosure layouts. Standard industry grades for heat sinks also include 6061 and 6082 alloys, which offer higher mechanical strength but slightly lower thermal conductivity than 6063.

These heat sinks are primarily used in telecommunications, automotive, and industrial automation sectors for cooling components like CPUs, IGBT modules, and power supplies. Buyers typically source these in bulk for OEM applications, with export-standard packaging ensuring safe transit. The supplier is based in Hebei, China, with a production facility in Shijiazhuang, and lists ISO 9001:2008 certification for quality management. Lead times are stated as 10 days after payment, with delivery terms to be confirmed.

Frequently Asked Questions About CNC Machining Aluminum Heat Sink from Hebei Xindongrui Alloy Material Technology co.,ltd
The heat sink is made from 6063 aluminum alloy, which has a typical thermal conductivity of 201 W/m·K. This is slightly lower than 6061, which offers around 167 W/m·K, but 6063 is preferred for heat sinks due to its better extrudability and smoother surface finish after anodizing.

Sourcing CNC Machining Aluminum Heat Sink from Hebei Xindongrui Alloy Material Technology co.,ltd - China Import Guide

Before ordering, verify the exact temper and thermal conductivity values for your application, as these directly impact cooling performance. Confirm whether the supplier can provide material test reports (MTRs) for the 6063 alloy to ensure it meets your specifications. Request samples to evaluate the anodized finish and surface quality firsthand.

Discuss logistics details such as Incoterms (e.g., FOB Shijiazhuang or CIF your port) and lead times, which the supplier states as 10 days after payment. Clarify whether this includes production and shipping time, and confirm the supplier’s preferred payment methods (e.g., T/T, L/C). Packaging should be inspected for export compliance to avoid delays at customs.

For quality checks, measure the heat sink’s dimensions and thickness to ensure they match your drawings, and verify the anodized coating thickness (typically 10-20 microns for durability). Test thermal performance under your operating conditions, and request a certificate of conformity (CoC) for the ISO 9001:2008 standard. Document all specifications and test results for traceability.
