bedra 35000
Leaded Brass
Characteristics:
It is commonly known as Medium Leaded Brass, prized for its excellent machinability, good mechanical strength, and corrosion resistance, making it suitable for a broad range of mechanical, electrical, and precision applications where efficient manufacturing and durability are critical.
Typical applications:
It is widely used in bearings, gears, bushings; valve stems and plumbing valve components; screw machine parts such as screws, nuts, bolts, and knurling/thread rolling components; and precision components including clock and watch parts, meter components, lock components, and key blanks.
