Highly Quality Aluminum Heat Sink-FAQ's
What alloys are used for your high-quality heat sinks?
We primarily use 6063-T5 and 6061-T6 aluminum alloys for their excellent thermal conductivity and machinability.
Can I choose the fin structure?
Yes. Fin configurations such as straight, pin, or skived can be customized to meet your specific cooling requirements.
Do you offer surface treatments?
Absolutely. We provide black anodizing, natural anodizing, and powder coating for protection and thermal radiation enhancement.
Are hybrid designs with copper available?
Yes. We can integrate copper into the aluminum structure to improve heat dissipation for high-load applications.
What is the standard lead time?
Standard lead time is 10-15 business days depending on the design complexity and order size.
Can I order small quantities for testing?
Yes. We support prototyping and small batch orders, with full scalability for mass production.
What industries do you supply?
We serve LED, power electronics, telecom, automotive, and industrial automation sectors globally.
