16*16*12mm Aluminium Hot End Heating Block Various Thermistors For 3D Printer J-head Extruder - Red Black

About the use of heating block: The heating blocks are produced with high-purity aviation aluminum by the machines. The inherent of aluminum is prone to scratches, and the will get dark after long time placed, so we work with a professional anode factory to make four colors for the appearance of the heating block, namely, silver, black, blue and red, to ensure the beauty of the product.
About the changed after some time use of the heating blocks: Due to technology limited, the anodized metal surface is for appearance use. After the use of aluminum block, the will change because the on the metal surface will get evaporated during the high temperature heating, including the natural aluminum block, just not that obvious. (For example, a black frosted heating block will turn yellow when it is heated at a high temperature). But it will not affect the use at all.
