Additionally, because of its unrivalled heat resistance, Brass C206000 is frequently used in the electronics industry to fabricate components that must endure extreme temperatures.

Heat Treatment & Machining

Brass C206000 can be heat treated to improve its mechanical properties by inducing a stronger grain structure within the metal alloy. Heat treating also increases the hardness factor, making it easier to machine. Still, care must be taken not to overheat the material during this process, which could cause permanent damage or even cracking in extreme cases. The machinability rating for Brass 260 is around 80%, which means that with proper cutting tools, this material can be easily machined into complex shapes without too much difficulty or effort on behalf of the operator.


In conclusion, Brass Material is a versatile metal alloy with superior strength and excellent corrosion resistance. It is perfect for use in applications where exposure to moisture or other corrosive elements may occur, such as plumbing fixtures or hardware components exposed to salt water or marine environments. Its easy machinability allows operators to easily shape this material into complex components without too much difficulty. In contrast, its heat treatment capabilities allow users to tailor their component’s mechanical properties to specific requirements if necessary. For these reasons, Brass 260 has become one of the most popular brass alloys. Whether you’re looking for a durable component that won’t corrode easily, need something that’s easy to machine, or want something with higher mechanical properties, look no further than Brass 260!
