Consortium Works to Improve No-Lead Copper Alloy Castings Copper metalcasting facilities con-
These and other consortium
sidering adding no-lead brass options to their product mix should know that most of the materials are more difficult to handle during manufacturing and cost more than their leaded counter- parts, according to the findings of the American Foundry Society’s (AFS) No Lead Consortium.
findings will be discussed during the AFS Copper No-Lead Workshop, Sept. 21, at AFS Headquarters, Schaumburg, Ill. Te consortium’s research was
spurred by California legislation that took effect on Jan. 1, 2010, which requires that copper-based products
meant for potable water use must have a maximum of 0.25% by weight of lead in the alloy composition, accord- ing to the consortium’s report. Topics at the event will include
metallurgical and production issues, such as pouring temperatures and gat- ing techniques, as well as machining, soldering and plating.
New Handbook Explores Methods of Casting Magnesium Metalcasters, design engineers,
metallurgists and materials scientists interested in using or learning more about magnesium can now pick up a copy of “Magnesium Castings: Design, Products and Applications,” a new American Foundry Society (AFS) publication. Te handbook features magne-
sium-specific information on melt and process control, solidification, heat treatment, materials selection and various casting processes, includ- ing sand, permanent mold, high- pressure die, lost foam, ablation and semi-solid casting. Te book’s publication is timely in light of the important role magnesium
plays in the transportation industry and other industrial applications that use the latest casting and processing technologies. Magnesium is a struc- tural material with low density and a high strength-to-weight ratio, and it can reduce vehicle weight and, in turn, reduce greenhouse gas emissions and increase fuel economy.
