5.375" Wide Extruded Aluminum Heatsink

the rest of the parts worked

I sure was surprised at the exceptional build-quality of the Aluminum Heatsink Products I recently received from HeatsinkUSA noting the material thickness and weight that leads to great outstanding thermal performance characteristics. This product has shown that it is well worth the cost. Thanks for the attention give to quality..

I got a custom cut heat sink. Great service product as described. Easy to order and good turn around. Good source for hobby projects like RF amplifiers.

I ordered a couple small pieces of the 5.375" heatsink for an amatuer radio project I am working on. The materials I received were cut to size perfectly and are of very high quality.

Bought 2 of these heatsinks 3 inches deep for a DIY amplifier build. They can quickly, maybe a week and a half, despite the COVID statement they have that certain industries will be prioritized over other orders, so I was happy about that. Came very well packaged, no threat at all that these beefy sinks would have been dented. As far as the sinks themselves, very well machined, identical to each other, no burrs or super sharp edges, seems like good base aluminum that they're working with in the first place. Price, product, and service have all been great, would definitely buy from again.

Arrived fast and extremely well packed

In general very good quality. Initial unit had considerable bow across width but this part was very quickly replaced by an acceptable heatsink.

Finally lots of fins and THICK base! 50W LED here we come!

Great to be able to find parts for our project locally but still be at reasonable prices (unfortunately harder and harder to do for a lot of things)!
