Composite Metal Foams and Their Applications

Metal foam is a porous material consisting of open-cell, closed-cell, or composite cavities. Open-cell metal foam has an interconnected network of pores. Closed-cell metal foam is similar to open-cell, but is sealed and may not have interconnectivity of internal pores. Composite metal foam combines a matrix of hollow metal beads of one material, such as steel or nickel, within another material, such as aluminum.

The 4 Best Digital Calipers on the Market

Each digital caliper, after being subjected to grinding dust, coolant splash, machining chips, and being handled by multiple people, has kept readings within .0005” of the target value. This means the calipers have not degenerated in accuracy at all with respect to the manufacturer’s given resolution and measurement accuracy numbers.
