With the legislation passed in California (AB1953) and Vermont S152) serving as a catalyst for a national interest in the lead free regulations for potable water, a National Lead Free Bill was signed by President Obama in January 2011. This Senate Bill S.3874 (aka: Reduction in Lead in Drinking Water Act) that was signed will reduce the lead content in faucets, fittings and valves from 8% to no more than a weighted average of 0.25% maximum lead when used with respect to the wetted surface of pipes, plumbing fittings and fixtures or other potable water applications. This law will go into effect nationally January 1, 2014.
In conjunction with the expanding interest in lead free and low leaded brass alloys for potable water applications and lead free regulation compliance, Mueller Brass Company has developed the EcoStream™ family of alloys and products...
EcoStream™ is a family of lead free and low lead brass alloys and products specifically developed to aid companies and manufacturers with their lead free compliance strategies for their products and components.
Whether the need be for components machined from Mueller Brass Company’s GreenDrop™ C27450 Lead Free Brass alloy or forged parts from C37000 Low Lead Forging Brass, the EcoStream™ family of alloys and products provides further benefits by offering additional benefits for the manufacturer in areas of raw material costs and manufacturing productivity when compared to other lead free or low lead alternatives.
With the customer in mind, Mueller Brass Company has developed Green Drop™ C27450 Lead Free Brass Alloy a practical solution for manufacturers seeking compliance to lead free regulations and legislation for their products.
Compliant – Competitive - Compatible
Unlike other lead free and low lead alternative alloys, GreenDrop™ C27450 was carefully developed with an industry-centric approach to address the specific needs of the manufacturers themselves. Instead of just purchasing the rights to an alloy originally developed for other purposes, Mueller Brass Company developed GreenDrop™ C27450 alloy specifically for those manufacturers needing an alloy to produce products and/or components requiring compliance to lead free regulations. In addition to being COMPLIANT, Mueller Brass Company also recognized the necessity for the alloy to be COMPETITIVE to help minimize the incurred costs associated with transitioning of existing products and the development new products to comply with these new standards.
No Silicon – No Bismuth – No Segregation
By carefully controlling the percentage of constituent elements required, and not introducing costly and potentially detrimental additives like silicon or bismuth, GreenDrop™ C27450 provides a competitive advantage over other lead free brass alloys. In addition to advantages in raw material costs, manufacturers also realize further cost savings in manufacturing productivity and efficiency. Because scrap generated from GreenDrop™ C27450 Lead Free Brass is completely COMPATIBLE with scrap from standard, commonly used alloys, the need to clean out machines and segregate scrap is virtually eliminated. Combined with superior performance in thread rolling, plating and brazing, GreenDrop™ C27450 Lead Free Brass Alloy is the perfect solution for machined parts and forged parts applications.

When California first initiated lead free legislation, Mueller Brass Company conducted an industry-wide seminar to discuss the effects on the industry, manufacturers and possible solutions for compliance. As part of the seminar, various speakers ranging from manufacturers to industry organizations offered their viewpoints and perspectives with regard to AB1953. As one of the participants, Robert Weed of the Copper Development Association (CDA), presented an excellent overview of the legislation, and offered insight and clarification to many questions surrounding the law. A copy of the presentation has been made available for reference and can be downloaded below:
To further aid customers and manufacturers in their transition and adoption of Lead Brass Alloys, Mueller Brass Company has developed a “Machining Reference Guide” and a “Troubleshooting Guide”. These two pieces were designed as supplements to help minimize the learning curve associated with machining lead free and low lead brass alloys.
