Honed tube is widely used to make hydraulic cylinders and pneumatic cylinders, for different applications the different materials are required. The materials of honed tube normally include aluminum, carbon steel and stainless steel. The materials of honed tubes for hydraulic cylinder tubes are carbon steel and stainless steels; while the material of honed cylinder tubes for pneumatic cylinder tubes usually is aluminum.
