Boron bronze, also known as boron copper, is an alloy made of copper and boron. It is known for its high strength, wear resistance, and low coefficient of friction. The term boron bronze may also refer to other copper-based alloys containing boron as an additive, such as beryllium-copper-boron and silicon-bronze-boron. Synonyms of boron bronze include copper boride, boronized copper, borocopper, and borocopper-tungsten. These alloys are widely used in industries such as aerospace, automotive, and manufacturing due to their unique properties and ability to withstand high temperatures and corrosive environments.
