..., and washers. As a coating on wire or sheet metal, lead acts as a drawing lubricant, and in the form of powder, it imparts lubricity to antiseize compounds and engine bearings. The malleability of lead is used to greatest advantage in the manufacture of foil; lead foil often is rolled as thin as 0.01...

... cylindrical cups punched from thin aluminum foil. After quenching, the foil was peeled from the specimen, and the hardness measurement was made on the flat surface (after the top surface had been quickly smoothed on a file to ensure proper seating in the test machine). Cooling curves were obtained for the...

The lower frequencies create larger bubbles with more energy, as can be seen by dipping a piece of heavy-duty aluminum foil in a tank. The lower-frequency cleaners will tend to form larger dents, whereas higher-frequency cleaners form...
