Custom aluminum anodizing service?

[StDragon]

Not sure where best to post this (figure cases given the modding scene), but I've got a bare aluminum heat-sink that I want anodized black. Is it an expensive process? Does anyone have an online service they can recommend? I'm willing to mail off the part, have it anodized and shipped back.

My guess would be a place that restores old cars.

Usually they charge the part by weight and complexity, most placed have a minimum order amount you must meet before they will do any anodizing. Some may group smaller orders together and batch specific colors in one big order.

 

Best is to check locally for specialized coatings or treatment places, conversion coating places usually will have anodizing as an option. 

 

If you can't find one you can use a ceramic (high temp) based coating to paint the heatsink which will hamper the cooling capability a little but get the look you want.
