Free Machining D.Z.R. “Lead Free” Brass

Free Machining DZR “Lead Free” Commercial Brass has excellent machinability, 90% min (when compared to C360 Brass), and has mechanical properties similar to traditional free cutting brasses. It also has outstanding conductivity 37% IACS min (45% higher than C360 Brass) and does not contain Silicon, Bismuth, or Arsenic. It has excellent cold working abilities, thread rolls very well and can be electroplated like copper.

Cu-Zn alloys containing more than 15% Zn are susceptible to a de-alloying process called dezincification “D.Z.R.” or white rust, where the selective removal of Zn leaves a relatively porous and weak layer of copper and copper oxide. This is also considered as stress cracking and creates catastrophic failures.
Free machining dzr “Lead free” commercial brass contains less than 15% zinc, and therefore is a true DZR Brass, with guaranteed corrosion resistance.
Distinct advantages of free machining dzr “Lead free” commercial brass
25-40% Higher yield strength than C360 Brass
Significantly higher elongation over C360 Brass
45% Higher electrical conductivity over C360 Brass
