White aluminum trim coil is widely used in all walks of life, especially building decoration such as shutters, ceiling, roofing system,etc. The good plasticity and machinabilty of the color coated
aluminum coil make itself an ideal decoration material. For getting the needed size, how to slit it without causing damage to the coating?The most important thing for aluminum trim coil slitting is the blade. In order to make a qualified blade, we need to know which material is most suitable for slitting
aluminum coil. Silicon has a corrosive effect on carbide. The gradual increase in silicon content will gradually increase the destructive power of
aluminum coil on tools.Therefore, some manufacturers recommend diamond tools when the silicon content of the aluminum trim coil for sale exceeds 8%. However, another carbide blade, without aluminum element,with thin film thickness and physically coated,can be also used.That is because the PVD method and small film thickness make it possible for the blade to maintain a sharp cutting edge. And if the film material contains aluminum, it may cause affinity between the film and the
aluminum coil, thus breaking the combination of the film and the blade base.At present, the super hard coatings of the blade are mostly compounds of aluminum, nitrogen, and titanium. With the peeling of the coating, the blade base will be damaged and then cutting edge may be distorted.The following three types of cutting tools are recommended for slitting white aluminum trim coil:Ultra-fine-grained carbide bladeCarbide tools with no-aluminum coating and physically coatedDiamond toolsAs a professional aluminum trim coil manufacturer, Haomei has strict manufacturing process and quality processing tools, If you like to know aluminum trim coil prices, welcome to contact us.
