Brass Rods: The Sustainable Choice
Brass rods have a powerful lineup of green attributes, making them the sustainable choice for manufacturers and end-users of precision machined and forged parts.
This infographic, from the Copper Development Association, shows how brass rods can reduce emissions in machine shops, be recycled without losing properties, and contribute to a cleaner environment.
The Brass Rod Circular Economy
The metallurgical properties of brass allow pre- and post-consumer sources of brass scrap to be recycled with no loss in properties.
Brass scrap can retain over 90% of the original material value. In addition, brass doesn’t need energy-intensive processing, unlike steel and aluminum, which must be smelted and refined before being recycled into new products.
As a result, there is a greater chance that steel and aluminum scrap will end up in landfills.
Most brass-rod alloys produced in North America contain 95% or higher recycled content.
Closed-loop recycling of brass keeps this valuable engineering material out of landfills, reducing the need for new mines and all the environmental impacts that entails.
Higher Machinability Leads to Lower Operational Carbon Emissions
Machinability is how easily a material can be worked using cutting processes. It directly impacts the amount of energy required to produce finished parts.
With typical machine shops producing millions of parts each year, the carbon impact can be significant.
Here’s how brass and steel compare when manufacturing complex parts using computer numerical control (CNC) machining.
| Material | Brass | Steel |
|---|---|---|
| Type | Free-cutting brass (C36000) | Free-cutting steel (12L14) |
| Maximum machinability rating (0-100) | 100 | 21 |
| Metal Removal Rate (cubic inches per minute) | 0.238 | 0.114 |
| Time to remove material (hours) | 161,111 | 336,111 |
| Energy required to produce parts (kilowatt-hours) | 9,475 | 18,931 |
In this example, using brass represented a savings of 3,510 kg in carbon dioxide (CO2).
The significantly longer tool life enabled by brass also reduces the need for new cutting tools, further decreasing emissions.
High recycled content and exceptional machinability make brass rods the sustainable choice for manufacturers and end-users seeking to reduce their environmental footprint and support the transition to a low-carbon future.
