Manufacturers must exercise care during the annealing heat process to prevent the re-formation of brittle iron. The application of a special annealing heat treatment causes this metal to lose its brittleness, while also changing the internal microstructure to render it more flexible. Manufacturers produce malleable iron by first casting a brittle product known as “ white iron.” Cast white iron contains carbon inclusions and offers surface hardness. It offers ductility and strength but sometimes shrinks in size during cooling. Malleable Iron: This cast iron product contains less carbon than conventional gray iron. Ductile iron castings display spheroidal carbon inclusions within the iron on a granular level, a factor which contributes to enhanced ductility. Gray Iron: Noted for its characteristic gray color, gray iron castings have gained wide use in numerous modern industrial applications.ĭuctile Iron: Manufacturers create ductile iron by applying Magnesium to the ferrous metals used in the production of gray iron. They include gray iron, ductile iron, and malleable iron. Three popular different cast metals frequently contribute to metal parts manufacturing and assembly operations. Iron CastingsĬasting today creates many commercially important products. The casting process promotes important microstructural changes in cast metals. This material solidifies as it cools, ultimately hardening into a shape determined by the mold cavity. The factory implementation of modern enterprise management mode, passed ISO9001:2000, and fully implemented the management system.įor the convenience of customers, our factory can custom all kinds of mould to provide one-stop services from drawings to deliver castings, we uphold " customer focus and exceed customer expectations "business philosophy, in good faith and pragmatic, sincerely welcome the global merchants to patronize, complicity development, create brilliant.During the iron casting process, a manufacturer deposits molten iron and ferrous alloys into a mold. Can ensure customer demands for all kinds of casting material. We have the physical and chemical laboratory, have the spectrum analyzer, digital ultrasonic flaw detector, and the hydraulic universal material testing machine, metallographic microscope, coordinate measuring machine and other testing equipments.
