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…

Types of Welding Metals

 There are a number of different types of metals which are acceptable for welding. It is important to know how to weld specific welding metal types so that you have the correct welding equipment on hand to properly get the job done. Welding Aluminum Welding aluminum requires high power welding and very clean oxide-free surfaces. Cleaning a surface to be…

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…

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…

Casting Alloys

The wide range of casting alloys helps in selecting the most suitable and cost effective material that meets the requirements of a particular application. Each of these casting alloy has its own physical and mechanical properties. They also have their own casting characteristics, like: Weldability Machinability Corrosion resistance Heat treatment properties Did You Know Bronzes are unquestionably the most versatile…

Exploring alloy-based protection

Will alloy-inducing anti-corrosion agents make metal blasting a thing of the past? By Merrick Alpert Metal blasting (or sandblasting) has long been a go-to process to treat metal before the application of a surface material, such as an anti-corrosive agent. But as alloy-inducing anti-corrosion agents take the stage to compete with traditional barrier coatings, surface preparation will change. To understand why, we…

What are the Differences Between Various Nickel-based Metals and Alloys?

Nickel alloys are used extensively in industry due to their resistance to corrosion and ability to withstand high temperatures and pressures. Nickel alloys resist high pressures and temperatures, making them well-suited for high-performance applications such as jet-engine blades. They also resist corrosion. That’s why Monel is used in deep-seal mining, where seawater poses a constant threat of corrosion. Nickel is…

What Engineers Should Know about Zinc-Nickel Coatings

The development and practical application of electroplated zinc-nickel alloy coatings began during the 1980s, and its acceptance and use have grown slowly but consistently ever since. So Zn-Ni coatings are not as widely used as other traditional protective coatings. This is unfortunate and likely due to the fact the process and the benefits it brings are subject to some misconceptions.…
