C27450 – Low Lead Brass Rod Products

C27450 is a lead-free brass that was created in response to requirements for lead-free brass in the plumbing industry. This requirement for lead-free brass in the plumbing industry was established in 2011 and enacted in 2014.

This alloy can be substituted for Alloy 377 without compromising the integrity of the finished part. This indicates that a product can be made that delivers similar strength, corrosion resistance, and quality at a cost savings benefit.

There are several advantages to using C27450. C27450 is also compliant with both S3874 and AB1953. The alloy is easily recyclable due to the components it’s made of, and does not require segregation. C27450 is considered to have good machinability, making it possible for more components to be machined per hour. C27450 easily solders and brazes and has good thread rolling capabilities.

Typically, the end use is lead-free plumbing products that meet plumbing legislative requirements.

C27450 comes in various shapes, such as, hexagon, round, square, and other shaped brass rods and brass bars.

PUSHING PRODUCTIVITY TO THE LIMIT: HIGH SPEED MACHINING OF BRASSES

Inspired by a new focus on using brass products and advancements in high speed machining and tooling, the Copper Development Association conducted third party machinability testing on both leaded and lead-free* brasses using single point turning and drilling operations. What was found was fantastic! Anyone processing brass has an opportunity to decrease cycle times by as much as 94%. Who would have guessed that despite the reputation of brass’ machinability, of its capability has been underutilized, thus inflating the cost per part and decreasing potential profitability. The CDA study was performed on 5 brass alloys machined at different speeds and feeds...

6 Considerations for Selecting the Correct Brass for a Given Application

To the unknowing eye, brass is brass. But we in the industry know there are many variables in brass alloys which are used in wide ranging applications. In order to effectively select the correct brass for a given application, critical attributes of the final product have to be considered, including: End Use Application – Does the application require leaded, low lead or lead-free* brass. Is the product for a mechanical, ornamental, electrical, potable water conveyance, medical or others? Chemical Properties – There are many variations of brass alloys because some applications may require additional elements added which can make the...
