Cordite's use was further developed in the early years of World War II, for launching 2-inch and 3-inch diameter non-rotated, anti-aircraft projectiles. Small cordite rocket charges were also developed for ejector seats made by the Martin-Baker Company. Cordite is now obsolete and it is no longer produced. It has been replaced by other propellants, such as the Improved Military Rifle (IMR) line of extruded powder or the WC844 ball propellant currently in use in the 5.56 x 45 mm NATO.

Pearlite is hard as well as strong because of the layered structure, and is used in a variety of applications.eople can identify pearlite by studying the structure of the alloy. Particularly, under a microscope, it has a very distinctive appearance created by the lamellar bands. Pearlite is around the middle of the chart in terms of strength when compared to other iron alloy phases.
