Metals

Introduction: The discovery of metals was the stepping stone towards civilization. The metal are known to man form the pre biblical times and different civilizations used the metal to make products for religious, hunting, weapon, house hold and ornamental purpose. Now, man is dependent on metal for cooking to traveling. A separate department called the metallurgy studies the entire process of…

Uses of Alloys

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…

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…

Aluminum Casting Processes

Aluminum is one of the few metals that can be cast by all of the processes used in casting metals. These processes, in decreasing order of amount of aluminum casting, are: die casting, permanent mold casting, sand casting (green sand and dry sand), plaster casting, investment casting, and continuous casting. Other processes such as squeeze casting, and hot isostatic pressing…

A Quick Guide to Ferrous Metals

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…

Definition

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.…

Components for Pumps & Valves

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…

Commercial Foundry

A Foundry deals with casting techniques, a process where the melted liquids are poured into moulds. This forms the first step towards manufacturing a product. Foundry Industry plays a vital role in the industrial development. Started as early as 3600 BC, the foundry industry has flourished very well and is likely to grow further. Castings are used for variety of…

The Metal Casting Operation

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…

Casting Process: Basic Steps

Industrial Process DescriptionThe metal casting process has been divided into the following five major operations: Obtaining the Casting Geometry :The process is referred as the study of the geometry of parts and plans, so as to improve the life and quality of casting. Casting Pattern-making :In pattern making, a physical model of casting, i.e. a pattern is used to make…
