Top 100 Key Players companies in Ductility
by Most Patent Citation in the United States in 2020

The Ductility top 100 is Discovery PatSnap’ annual ranking of the top 100 Most Patent Citation Ductility Key Players in the United States. Discovery has identified the top key players, startups & unicorns, fast-growings, news entrants in 2020, ranking from differnt perspectives, including patent filing intensity, academic research capability, news media heat. The company list is generated from various data types.
Ductility is a measure of a material's ability to undergo significant plastic deformation before rupture, which may be expressed as percent elongation or percent area reduction from a tensile test. According to Shigley's Mechanical Engineering Design (10th Ed.) significant denotes about 5.0 percent elongation (Section 5.3, p. 233). See also Eq. 2–12, p. 50 for definitions of percent elongation and percent area reduction. Ductility is often characterized by a material's ability to be stretched into a wire.
