Introduction of HPB 59-1 lead brass bar
Material name: HPb59-1 lead brass
Standard: (GB/T5231-2001)
China lead brass standard grade
The first letter "H" of the brand indicates brass, followed by two digits indicating average brass content, followed by symbols and numbers indicating elements and their content, such as HPb59-1 indicating copper (" H ") content of about 59%, and lead ("Pb") content of about 1%.
Features and Scope of Application:
Lead brass, which is widely used, is characterized by good machinability, good mechanical properties and ability to withstand cold. Hot pressure processing, easy welding, fiber welding, good stability to general corrosion, but there is a tendency to corrosion rupture, mainly used in air conditioning valves, hardware machinery and so on.
