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.

Choosing the Right Solder Alloy and Flux

Melted solder is attracted to metal but will not stick easily to metal with oils and oxidization. Flux melts at lower temperatures than solder alloys and is used to coat the area to be soldered and guarantee a clean joint. Flux helps draw solder into a joint and makes it easier to create a capillary action.

How is Buoyancy Calculated on a Submerged Object?

Buoyancy is the upward force on an object that counteracts gravity and other downward forces present. A submerged object in some fluid medium will experience a force due to gravity, a force due to buoyancy, forces due to wave energy, and other forces - the net force will determine whether the object floats or sinks and its rotation.

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.
