UR Physical Properties
  UR's physical properties of gravity and electrical conductivity are not so different from general free cutting brass rod and forging brass rod. Because the gravity of UR is 5% lower than C83600 (Leaded Red Brass), it is 5% lower in weight, resulting in better cost performance.
