Cesium is a silvery-white, shiny metal that is very soft and ductile. Ductile means capable of being drawn into thin wires. Its melting point is 83.3°F (28.5°C). It melts easily in the heat of one s hand, but should never be handled that way. Cesium s boiling point is 1,300°F (705°C), and its density is 1.90 grams per cubic centimeter. 

Copper metal is fairly soft and ductile. Ductile means capable of being drawn into wires. Both heat and electricity pass through copper very easily. The high electrical conductivity makes it ideal for many electrical purposes.

Table 3 shows that Avicel PH 102 and PH302 formed powder compacts with similar relatively high dynamic indentation hardness, whereas that of Avicel PH 105 was considerably lower, indicating PH 105 was the most ductile of the three compacted materials. Relative to other excipients, the values for these materials were fairly low, indicating greater ductility. Ductility is a desirable trait that promotes bonding and strength in tablets. 

Relatively short-time tests indicate that austenitic stainless steels are ductile at all temperatures. This conclusion should not be considered valid for steels exposed to thousands of hours at process temperatures. Long exposures between, roughly, 800°F and 1,600°F precipitate chromium carbide and sigma phase in many stainless steels, causing a significant loss in atmospheric-temperature ductility. Ductility at higher temperatures is less affected. 

Ductility is the ability of a material to deform easily upon the application of a tensile force, or the ability of a material to withstand plastic deformation without rupture. An increase in temperature will increase ductility. Ductility decreases with lower temperatures, cold working, and irradiation. Ductility is desirable in high temperature and high pressure applications.

This suggested that the metal might not have been as ductile (ductility is the ability to stretch without breaking) as it should have been. In 1994, tests were conducted on small pieces of metal, called coupons, cut from the recovered piece of hull. These samples shattered without bending. Further analysis showed that the steel used to constract the hull of the Titanic was high in sulfur content, and it is known that sulfur...
