  1. Fast delivery and great quality

    Posted by Rick, Dearborn, MI on 17th Nov 2012

    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.

  2. Fast & perfect!!

    Excellent quality and fast delivery.

  3. Fast! Cut & shipped in 1 day

    the cut is clean, to the exact length spec.
    Also inexpensive. If a profile choice is acceptable for your application, this is the way to go.

  4. Extremely Pleased

    Posted by Ray on 11th Sep 2012

    Excellent quality, great price, clean cuts, and reasonable shipping. What more could I ask for?

  5. First choice for heatsinks

    Posted by JT on 29th Aug 2012

    Fits my power application perfectly.
    The quality of the heatsink is excellent. It needs no surface coating at all.

    Very competitive pricing as well. From this point I just pick a length and a type and I have what I need. Great company to do business with. I actually talked to a real person that cares about the customer.

    I am using TO-247 packages with mica insulators with a single 3/4" x 0.125" bar to hold them in place. Three non-theaded holes secures the devices with ease.

  6. Quality product

    Posted by Greg on 18th Aug 2012

    Very well made, extruded, product, at a very competitive price. Used for heat disapation on prepackaged LED light packs, on truck trailers. Performed as expected. One low price for multiple length cuts is great. We can not set up and cold-cut for that cost. The thermal adhesive made installation even quicker. We did block sand the back surface of the heat sink for a flatter, more thermal conductive surface. Excellent customer service(thank you Jackie), well packaged, and reasonable shipping costs. Will buy from again.

  7. worked great

    Posted by Chris, M on 30th Jul 2012

    Nice looking product. So nice I left the top of the heatsink viewable on my aquarium hood MOD. Got a couple of Wows out of that. This is now my goto company.

  8. Great for DIY LED

    Posted by Chris, B - Austin TX on 20th Jul 2012

    This stuff worked great for my DIY LED for my aquarium. It was however a huge PITA to drill & tap. In the future I may ask to have it machined, or just use thermal adhesive instead. But that was my own mistake, not on the part of heatsinkusa.com! Great product, will buy again.

  9. Heat Sinks in general

    Posted by Tom on 24th Jun 2012

    because of their willingness to cut to length and good product selection I find myself shopping here first when I need a heatsink for a new project.
