Basic Info.

Aluminum coil is a kind of metal product for flying shear after calendering and drawing and bending angle processing.

Aluminum coil processing technology

Silicon is corrosive to cemented carbide. Although aluminum alloys with more than 12% Si are generally referred to as high silicon aluminum alloys and diamond cutting tools are recommended, this is not absolute. Some manufacturers therefore recommend using diamond cutters when the silicon content exceeds 8% . Aluminum alloy with silicon content between 8% and 12% is a transition zone, which can be made by using either conventional cemented carbide or diamond tool. But the use of cemented carbide should be used by PVD (physical coating) method, aluminum-free, smaller thickness of the film tool. Because the PVD method and the small film thickness make it possible for the tool to maintain a sharp cutting edge (otherwise the aluminum alloy will not be sharp enough if the edge is passivated enough to prevent the film from growing abnormally at the Edge) , however, the aluminum-containing film material may cause the blade film to have the affinity with the workpiece material and destroy the bond between the film and the tool substrate. Because the superhard coating is mostly aluminum, nitrogen, titanium compounds, may be due to cemented carbide matrix with the film exfoliation when a small amount of exfoliation caused by avalanche.
