• Liquid (or dye) penetrant inspection is used for detecting surface breaking flaws such as cracks, or laps and folds in any non-absorbent surface. Surface flaws are easily identified using fluorescent penetrants under darkened conditions with UV lamps.

• Each metal type has a required hardness level in its finished condition. Hardness testing is a method of testing to determine the hardness of a specific metal. The test is done by using a specially designed, calibrated, indenter that is pushed into the material to a particular depth. The resistance of the material is translated to a hardness value. The hardness value is directly correlated to the materials tensile strength.

• Most materials have a unique conductivity value determined by their chemical composition and their respective manufacturing and processing method. Many specifications require a conductivity inspection to be performed to insure the components are within the specified range for the material type the component is made from.
