Leaded Brass Sheet & Plate
Overview
Leaded brass contains finely dispersed lead particles that act as a chip-breaker during machining, making it the material of choice for keys, locks, engraving, and high-speed component production. MEI offers two leaded grades — free-machining leaded brass and leaded Muntz brass — with uniform lead distribution achieved through controlled melting and casting at our own foundry.
