Larry Muller graduated from Case Western Reserve University in 1976 with a Metallurgical Engineering degree. After a short stint working in the iron casting division of Ford Motor Company, he went to Gould Inc. in their foundry division doing research work on aluminum-alloyed grey iron and then as Plant Metallurgist and Quality Manager at their Lake City, MN plant making non-automotive iron and aluminum pistons. In 1982, Larry moved to Brush Wellman where he did research work, alloy development and production support of beryllium copper, nickel and aluminum alloys in both wrought and cast forms. In 1992 he joined Wieland Chase (formerly Chase Brass) as Manager, Metallurgy and Technical Service where he’s been involved in process control, research and customer technical support. Since 2003, Larry has been focused heavily on process development, characterization and technical support of C69300 and C87850 forms of ECO BRASS. He has been heavily involved corrosion studies of it and other copper base alloys that serve the water fitting and fixture markets. Larry is a member of ASTM, AWWA and NACE.
Some technical papers and websites on brass corrosion repeat the same caution that dezincification will occur in alloys containing more than 15 percent zinc. A few will go beyond that simple statement to talk about efforts to solve this issue.
