bedra 27450
Regular Brass
Characteristics:
With a high zinc content, it is a cost-effective alternative to leaded brasses that does not sacrifice strength or quality, offering high strength, good hot and cold workability, as well as excellent machinability and brazing properties.
Typical applications:
This is a lead-free cutting alloy widely used in hardware, machinery, electronics, valve bodies, bathroom fixtures, and other industries. It is suitable for various deep drawing and bending parts, such as pins, rivets, washers, screw nuts, conduits, pressure gauge springs, screens, radiator parts, and more.
