Metal Casting Process

A mold is formed into the geometric shape of a desired part. Molten metal is then poured into the mold, the mold holds this material in shape as it solidifies. A metal casting is created. Although this seems rather simple, the manufacturing process of metal casting is both a science and an art. Let's begin our study of metal casting…

Advances in Aluminum: New Twists on an Old Material

From “transparency” and bubble-wrap-type material to a net-like sponge, we could very well be witnessing the Second Age of Aluminum. Aluminum in its modern form has been around for more than a century. In the 1880s, it was considered more valuable than gold, particularly because it was difficult to produce in a pure form. Ever since what is considered the First…

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.…
