introduction
Brass 260 in CNC Machining
Brass 260, also known as Cartridge Brass, is composed of approximately 70% copper and 30% zinc.
It has excellent machinability and produces small, fine chips during machining, and the material doesn't tend to gum up the cutting tools. Brass is typically machined at higher cutting speeds compared to steel. However, the specific speeds and feeds will depend on the CNC machine's capabilities, the type of cutting tool, and the complexity of the part being machined.
Brass has a naturally attractive golden color and can be machined to achieve a smooth surface finish. The machined parts may require additional processes like polishing or coating if a specific finish is desired. Moreover, aside from being corrosion-resistant, brass 260 has good dimensional stability and can hold tight tolerances.

TECHNOLOGY OVERVIEW
Basic Knowledge of Brass 260
What is Brass 260?
Brass 260 is a popular and cost-effective brass alloy. It is highly ductile and possesses good strength, finishing abilities, and corrosion resistance. It can be easily machined and cold-formed. However, it's unsuitable for projects involving contact with acetic acid, hydrochloric acid, nitric acid, or ammonia. Avoid soldering due to its high zinc content.
Furthermore, it has an appealing smooth, yellow brass finish that can be polished to a gold-like appearance or brushed satin finish. Unlike steel and iron, brass 260 forms a thin protective patina, preventing rust when exposed to the atmosphere. It is commonly used in architecture, electrical parts, fasteners, and ammunition casings.

FAQ
Machining Brass 260 Buying FAQ
360 has more lead for easy machining. 260 (Cartridge Brass) has less lead and is used for ammo casings, instruments, and trim.
260 is more ductile for forming; 280 is less ductile, suitable for strength applications.
No, 260 brass is not magnetic; it's a non-ferrous metal.
Cost varies; it is generally affordable. Basically, it depends on the market, supplier, and quantity.
