I designed round heatsink myself. Design is ready on concrete (cement). Now I going to melt an aluminium and going to pour this liquid aluminium on concrete (where hole for heatsink is ready) to give its size. Can I do like this way? Won't concrete damage at 630 deg centigrade? The concrete (designed shape) will hold such hot liquid just a few second, then I will use water to cool it down.
