You must have at least heard about the material acetal or Derlin once in your life which are engineering plastic. But most people don’t know about them unless they have a project related to them. Well, Derlin is a homopolymer and acetal is a copolym

Copper is a brilliant and reliable metal that has been in human use since the bronze age. Its alloys can have a range of hues. However, it has a tendency to change appearance, texture and metal finish and show patina on its surface with the passage of tim

The surface finish for metals can be done through different methods but all these metal restoration processes include pre-cleaning of the surface. The sandblasting technique is a mechanical method of cleaning a surface. The sandblast finish also causes ro

Aluminum alloy AA 7075 and steels belong to entirely different classes of materials. Their superiority depends upon their application. AA 7075 is the strongest alloy among 7xxx series and have very high strength to weight ratio. This property makes it a s

The Definitive Guide Metals usually have only a limited range of hues and appearances. Further, their surfaces are prone to wear, abrasion and chemical attack. Anodization has been seen as a surface enhancement technique since more than a century for v

AISI 4130 and AISI 4140 steels belong to family of medium carbon low alloy steels. Major alloying elements involve carbon, chromium and molybdenum. Major difference in these steels is their carbon content. Due to higher percentage of carbon in AISI 4140,

Sand blasting is an effective technique to modify the surface of the specimen. Materials which can be sandblast are woods, metals, steels, stones, brass, titanium, aluminums, and silver. Along with the modification of surface roughness, removal of corrosi

Anodizing is a famous electrochemical technique to develop colours on different metal and alloys. Anodizing of titanium is different than aluminum anodizing as it doesn’t involve any dye. An electrochemical process is implied and colour variation is

Steel has a broad range of alloys and stainless steel is one of them. 300 series stainless steel is very famous due to their unique properties. It has a high proportion of chromium that introduces rust free nature in alloy. The quantities of chromium and

As you know aluminum is one of the most demanding elements globally due to its extraordinary characteristics and properties. Mainly its corrosion resistance and lightweight nature makes it suitable for many domestic and industrial applications. Many of yo

Aluminum is a very demanding material in engineering applications because of being strong and lighter in weight. By adding alloying elements in Al alloys and providing heat treatment, its mechanical properties like shear strength and toughness further inc

Aluminum alloys are essential structural material for many industrial and engineering applications. These possess greater strength at subzero temperature. Due to their low melting point, the strength can be decreased at elevated temperatures. 7000 series

Alloys are made by combining two or more metals. It helps in enhancing the features of base metals and further modify their properties. Aluminum alloys are one of the most demanding materials because of their unique features and applications in engineerin

Aluminum has a protective oxide layer of Al2O3 which prevents aluminum from corrosion. Taking benefit from this property aluminum is anodized and an oxide layer is formed artificially over the surface of sample though an electrolytic reaction. This l

Steel is playing vital role in the infrastructure of any country and its prosperity which signifies steel as a backbone of economy. Steel has revolutionized the modern world in the field of construction, medical, food processing and in marine applications

Aluminum alloys are available in many grades and it is not an easy task to differentiate between them. This article provides you with a comparison of two of the most used tempering processes being used for aluminum alloys. These tempered alloys have the s

Metal surface finish charts are a reference tool used for assuring quality and precision in surface preparation. In addition to physical properties like strength, ductility or toughness etc. surface provides material an overall appearance. A smooth surfac

You must be wondering what is black oxide? It is basically a black oxides coat used to provide a good surface finish to machined components. Now the question arises, what is the black oxide formula and how to coat a material with this? In this article, yo
