Rectangular Aluminum Comparator Block

Product Details

General information about usefulness: •Aluminum Comparator Block is an artificial crack test specimen. • Al -Com blocks are used for Crack Detection using Red Penetrant as well as Fluorescent Penetrants. • It is advised to use Al-com Blocks separately for Red Penetrant and Fluorescent Penetrant. The blocks should be stored separately and should never be interchanged. Due to interchanging, crack formation may not match the photographs that represent the ideal testing results.  Information about the product and advice about Usage: • Al- comparator block is an Aluminum Alloy material. The material is heated to high temperature and subjected to quenching by immersing in a liquid. Quenching the component, results into generation of Cracks in the component. • The cracks are formed by crack generating process. Formation of cracks in general is similar, however, individual dimensions vary. • The cracks on every component are different in shape and size and are not uniform as on Ni-Cr Panel. • After crack formation, Al-Com block is cut at the center converting it into a pair of blocks of same size and shape. Since the cracks on every block are similar, the two blocks are helpful for comparison, such as crack detection procedure, performance of different Penetrants and skill level of testing persons. • Al-Com blocks can be cleaned by Ultrasonic cleaning method, and can be used repeatedly.  Advantage of the Product: • Al-Com block is supplied with the photographs of cracks, as detected by an expert testing person, which serves as a guideline for users. • The price of Al-Com block is much less than price of Ni-Cr panels. Al-Com blocks are used for providing practice to testing persons to become experts in crack detection process.Aluminum Comparator Block is an artificial crack test specimen.Al -Com blocks are used for Crack Detection using Red Penetrant as well as Fluorescent Penetrants.It is advised to use Al-com Blocks separately for Red Penetrant and Fluorescent Penetrant.
