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...
Malleability
Malleability describes the property of a metal's ability to be distorted below compression. It is a physical property of metals by which they can be hammered, shaped and rolled into a very thin sheet without rupturing. A malleable fabric could be planate by blow or rolling.Malleability in...
Shielded Metal Arc Welding
Shielded metal arc welding (SMAW) is a fusion welding process that uses a consumable, flux-coated electrode to create an arc between the electrode and the work piece. Molten metal travels from the electrode via the electrical arc and is deposited into the work piece. The flux coating is also melted...

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 corrosion rate between mils per year and mm/y?
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...
