Alloys are metallic substances composed of a mixture or metallic solid solution of two or more metals. They can even be composed of a metal and another element which may be non-mettalic to produce an alloy. An alloy usually has different properties from the elements that it is composed of. A variation in the concentration and ratios of elements produces alloys…
Almost every material we could ever want is lurking somewhere in the planet beneath our feet. From the gold we wear as jewelry to the oil that powers our cars, Earth's storehouse of amazing materials can supply virtually every need. Chemical elements are the basic building blocks from which all the materials inside Earth are made. There are 90 or so naturally…
Introduction to Metal Casting: From ages immemorial, metal has been a faithful companion of the human in peace or in war. To refine the metal that is unearthed from the core of the earth and to melt and shape them a variety of techniques has been developed, which is generally termed as castings. With the passage of time casting has progressed…
This article gives an overview of ferrous metals, what they are and how they're made There are several common types of ferrous metals such as mild steel, stainless steel and cast iron. Ferrous metals are highly versatile. Read this article to learn about their applications and advantages and disadvantages of ferrous metals Have you noticed how some materials rust over…
Casting is a method where a solid material is dissolved, heated to suitable temperature (generally treated to change its chemical structure), and is then added into a mold or cavity, which keeps it in a proper form during solidification. As a result, in just one step, complex or simple designs can be created from any material that can be dissolved.…
A variety of casting methods are used for making the components for pumps and valves. They can be done using either ferrous or non-ferrous casting methods. Using Ferrous Casting Pump and Valve components can be cast using the following processes malleable iron casting, gray iron casting and ductile iron casting. Advantages of each of the casting methods are enumerated below…
The automobile industry offers a huge market for the cast products using ferrous, non-ferrous metals and its alloys. Various casting methods are used to produce automobile accessories that are light in weight, easy to maneuver, and cheap. Zinc Die Casting and Aluminum Die Casting are two most popularly used processes to produce automobile casting equipment. Zinc Die Casting :By using…
Continuous casting, also referred to as strand casting, is a process used in manufacturing industry to cast a continuous length of metal. Molten metal is cast through a mold, the casting takes the two dimensional profile of the mold but its length is indeterminate. The casting will keep traveling downward, its length increasing with time. New molten metal is constantly…
Pouring, Fluidity, Risers, Shrinkage And Other Defect In the previous section the fundamentals of the metal casting process, as the basic starting point for metal fabrication and part manufacture, were covered. Setup and design of a system to perform a casting operation was explained. Main topics were molds, patterns, cores, and the elements of a gating system. In this section…
Founding, the process of pouring molten metal into a cavity that has been molded according to a pattern of the desired shape. When the metal solidifies, the result is a casting—a metal object conforming to that shape. A great variety of metal objects are so molded at some point during their manufacture. The most common type of mold is made of sand and clay; ceramics, sand with cement, metals,…
