Brass Is Copper – A Ten‑Point Engineering Deep Dive into High‑Performance Copper‑Alloy Bushings
Every brass bushing begins its life as copper. This is not a metaphor—it is metallurgical fact. Brass is fundamentally a copper‑based alloy, typically containing 60% to 90% copper, with zinc and other elements added to enhance strength, machinability, and wear resistance. Understanding that “brass is copper” unlocks a clearer view of the entire family of copper‑based bearing materials: pure copper, versatile brass, and the superior bronze alloys that dominate demanding bushing applications.
