Brass for CNC Machining

Brass is a flexible copper alloy that maintains certain advantages of copper while enhancing some of its properties. It is a metal with greater mechanical strength and reduced friction, providing superior resistance to corrosion and wear compared to pure copper.

Brass refers to a broad category of copper-zinc alloys. These alloys differ in zinc content and may include other elements like lead, aluminum, and iron. Due to its copper content, brass is both thermally and electrically conductive. It also exhibits excellent wear resistance. The addition of lead enhances machinability, making brass the easiest to machine among all copper alloys.

Brass is a flexible copper alloy that maintains several advantages of copper while enhancing certain characteristics. It is a metal with greater mechanical strength and reduced friction, providing superior corrosion and wear resistance compared to pure copper.

These characteristics make brass ideal for CNC machining in mechanical applications that demand corrosion resistance.

Brass Alloys

Brass C260

DUCTILITY, CORROSION RESISTANCE

Bronze C260 is a zinc-alloyed formulation with approximately 30% zinc with less than 1% lead and iron. This grade is sometimes referred to as cartridge brass thanks to its history of use in ammunition cartridges. Other common applications include rivets, hinges, and radiator cores.

Brass C360

MACHINABILITY

Bronze C360, commonly known as free-cutting brass, offers excellent machinability because of its relatively high lead content. Common uses include gears, screw machine components, and valve parts.
