1.813" Wide Extruded Aluminum Heatsink

I used these for quarter-brick power modules. The mating surface was very flat and smooth. Shipping was fast and customer-service was good for a special request I had.

The product is solid, with a small trial test pull heat quickly from the source. I placed my order and had it on my doors step 2 days later with the cheapest shipping option, much faster then I was expecting. Also the Packing was such that the product was very well protected for transit. Ends are clean without burrs and the lengths were accurate and straight, and the finish was pretty much blemish free. Conclusion: Great Quality, Fast Delivery, and I will definitely order from here again if I have future needs for heat sinks.

Used for a university engineering project. Product looks great and shipping was fast.

Delivery was quick and priced right. The extrusion was smooth and the mounting surface flat. End cuts were even with no burrs. Heatsink USA is in my opinion provides a quality product at very reasonable prices.

I ordered custom heat sinks with drilled and tapped holes per my dimension, they fit perfect and saved me long hours of doing them by hand. Thank you and look forward to doing more business with you in the very near future.

Great product! Great service!

Found these guys on the internet and couldn't be happer after receiving the heatsinks!!! Nice extrusion and clean cuts!!! Fast shipping, no complaints & very pleased!!! Great value for a great product!!!

It's just as advertised and obviously a quality product.

I spent a lot of time searching the web, trying to find a heat sink for my high-power LED project. The electronic supply houses didn't offer anything in the size I needed and their prices were pretty high. Then, I stumbled upon HeatsinkUSA. I couldn't believe I could buy an extrusion by the inch! I got what I needed at a fraction of the cost. The base of the extrusion is perfect to drill and tap to mount the LED. Their service is great. I'll be back.
