Definitions
Alloy – A metal created by mixing two or more metallic elements, typically to increase strength or corrosion resistance.”an aluminum, copper, and zinc alloy”
Tensile – The amount of force required to break the material, typically measured in pounds per square inch (PSI).
Yield – The point at which material (under applied pressure) will change its form and not return to its original condition, typically measured in pounds per square inch (PSI).
Elongation – A mechanical property of metal that is the degree to which a material may be bent, stretched, or compressed before it ruptures. It is a point between tensile strength and yield strength and is expressed as a percentage of the original length.
Brinell – A common hardness test done with a round, very hard steel ball which is pressed into the material being tested. The diameter of the mark left in the steel is measured and a table is used to convert this to a Brinell Hardness Number. The higher the number, the harder the steel. Resistance to indentation, scratching, abrasion, or cutting. Materials with little resistance are called soft; those with high resistance are called hard.
