Quality Assurance
International Control Standards & Batch Traceability
From 6-inch virgin aluminium billet inspection to automated aging furnaces and CNC surface finishing, quality control is documented at every step.
Batch Spectrometric & Hardness Verification
Every extrusion batch undergoes optical emission spectrometry to verify alloy chemical limits alongside Webster hardness testing post-aging for uniform structural integrity.
Anodizing & Emissivity Testing
Black anodized heat sinks are audited for film thickness (10–25 microns), cross-hatch adhesion, and salt-spray resistance to maximize thermal radiation performance.
Procurement FAQ
Frequently Asked Questions by Sourcing Managers
We primarily utilize alloy 6063-T5/T6 for high thermal conductivity (approx. 200-209 W/m·K) and excellent extrudability, and alloy 6061-T6 for applications requiring higher structural mechanical strength and post-CNC machining rigor.
Yes. Our in-house toolroom engineers custom H13 steel dies based on your STEP, DWG, or DXF files. Tooling is completed within 7 to 10 working days followed by dimensional sample validation.
We offer clear anodizing, black anodizing (enhancing surface thermal emissivity), chromate conversion coating (surtec/alodine), and powder coating according to ISO and ASTM international standards.
Each production lot undergoes chemical spectro-analysis, Webster hardness testing, 3D CMM dimensional inspection, flatness verification (tolerance ≤ 0.02 mm), and salt spray testing for coated products. Mill test certificates (EN 10204 3.1) are supplied with all shipments.
