Lists and reviews the technical literature on the effects of alloying additives on the dezincification of brasses.

Detailed results of rigorous salt-spray (fog) testing under ASTM B 117 and ASTM G 44 show C36000 brass parts significantly outperform E-coated and zinc-chromate-coated 12L14 steel parts.

Do you have questions about the Restriction of Hazardous Substances (RoHS II) exemption for copper and brass alloys? A ‘Frequently Asked Questions’ document is now available that includes key contacts for additional support. Updated November 2020.

Details physical attributes and economic benefits of Alloy 360. Discusses strength, machinability, recyclability of brass turnings and design flexibility.

Describes the development of CDA’s Universal Machinability Index and how it can be applied, using a nomograph, in the value analysis of screw machine products and parts. Includes case histories from commercial practice. Reprint, SAE Technical Paper 900365

This publication describes copper rod alloys with lead content less than 0.25%. Although this selection guide is primarily used for plumbing applications these alloys are extremely useful in any applications that require very low lead content.

This publication describes the superior machinability and economic advantages of brass for screw machine products. A cost comparison for parts made from brass and steel is included to show why brass is the cost effective choice.

This publication describes the environmental and economic advantages of brass as a result of its superior recyclability. The unmatched secondary value of brass is described and supported by a value comparison using actual production data. 

As the use of low or lead-free brass alloys grows, strict segregation of brass scrap is essential. Learn about the importance of the scrap stream, the issue of scrap contamination and proactive steps the industry is taking to secure the viability of the scrap stream for generations to come.

Professional care has been deployed throughout the brass value chain to ensure that brass materials and components for drinking water applications are in compliance with lead-free requirements.  This piece summarizes the North American regulatory landscape and reviews how producers and users of brass rod have adapted to meet new requirements. Updated November 2020.

Do you have questions about the European End-of-Life Vehicle Directive and how it affects copper alloys? A ‘Frequently Asked Questions’ document is now available which includes key contacts for additional support. Updated November 2020.

Professional care has been deployed throughout the brass value chain to ensure that brass materials and components for drinking water applications are in compliance with global regulatory requirements. This piece summarizes the European regulatory landscape and reviews how producers and users of brass rod have adapted to meet new requirements. Updated November 2020.

New findings from an extensive machinability research project demonstrate that brass rod can be machined at cutting speeds and feed rates significantly higher than current practice and recommended handbook values.

The high speed machining capabilities of brass enable significant productivity advantages and cost-savings compared to 12L14 steel and 304L stainless steel. This piece reviews extensive laboratory testing that assessed the maximum practical machining speeds for brass and steel alloys from the standpoint of productivity and tool life. An economic comparison on cost per part is also included.

Understanding compliance requirements for regulations that restrict lead (Pb) in materials and products can be a daunting task. The simple matrix below is intended to help manufacturers readily identify commercially available brass rod solutions that meet U.S. and European “lead-free” compliance requirements in regulated markets.

Case histories of screw machine products which have been converted from leaded free-machining steel to free-cutting brass, Copper Alloy No. C36000. Design details, cycle times, productivity gains and cost savings (bare and plated) are presented:
