HeatsinkUSA, LLC is a family owned and operated business in Belding, Michigan, USA. We started by selling aluminum heatsink material online at auction websites. We quickly realized there was a market for selling affordable extruded aluminum heatsinks to hobbyists, small businesses and R&D departments just to name a few. By purchasing in larger quantities, we are able to pass on significant cost savings to our customers who may need only a few heatsinks at a time. Thanks to our wonderful customers, we have quickly grown and are now selling our heatsinks worldwide. We believe in providing the lowest possible price to our customers without sacrificing quality or customer service. We appreciate you taking the time to visit our website. Please contact us if you have any questions or comments.
