Tensile Strength
Tensile strength is the ability of a material to withstand a pulling (tensile) force and refers to the breaking strength of a material when applying a force capable of breaking many strands of the material simultaneously, at a constant rate of extension/load. It is customarily measured in units of...
Thermoplastic
A thermoplastic is a type of plastic made up of polymer resins that becomes a soft material when it is heated and becomes hard when it is cooled. These materials are easily recycled and do not show any chemical property changes when they are heated or cooled multiple times. When thermoplastics are...
Shear Strain
Shear strain is the ratio of displacement to an object’s original dimensions due to stress, and is the amount of deformation perpendicular to a given line rather than parallel to it.In engineering, shear strain is the tangent of the angle, and is equal to the length of deformation at its...
How to Control Corrosion by Improving Design
Material selection is the key parameter for controlling corrosion, but we cannot neglect the importance of proper design.

The 8 Most Common Forms of Metal Corrosion
The type of corrosion likely to form on a particular metal surface is dependent primarily on the exposure environment and the metal’s physical and chemical properties.

5 Ways to Measure the Hardness of Materials
Hardness is not defined by any one universal scale or unit of measure. Several tests are available to assess this property, with each having its own unique set of advantages and disadvantages.

Does zinc rust?
The short to the question is, yes. Zinc does rust. Like all metals, zinc corrodes when exposed to air and moisture. However, this element does not rust like most other metals.Iron, for example, reacts with water and oxygen in the atmosphere to form hydrated iron (III) oxide on the surface of the...

How can I convert the corrosion rate between the mils per year and the metric equivalent millimeter per year (mm/y), and why does this matter?
A corrosion rate conversion is a technique to change the measurement units of a given corrosion rate to another unit for comparison purposes or a specific engineering application. When converting a corrosion rate between these units you must keep in mind that a mil is a thousandth of an inch (i.e.,...

What are the different Xylan coatings and how do I decide which is best?
Xylan is an industrial dry film lubricant consisting primarily of one or more fluoropolymers including polytetrafluoroethylene (PTFE) (Figure 1), perfluoroalkoxy alkane (PFA) and fluorinated ethylene propylene (FEP). This coating is generally used to reduce friction, improve wear resistance and...
