Description:
H63 has good mechanical properties, can also be plastic in cold state, has good machinability, is easy to weld and fiber weld, is corrosion-resistant, but prone to corrosion cracking. In addition, it is inexpensive and is the most widely used ordinary brass variety.
Applications:
Various load-bearing parts manufactured through deep extension and bending, such as pins, rivets, washers, nuts, conduits, pressure gauge springs, screens, radiator parts, etc.
