This is a full 500mm Barss Falt Bar H62 grade.

The average copper content of H62 brass is 62% ordinary brass,
62—The average content of copper elements; copper alloys with other elements added on the basis of ordinary brass are called special brass,
 
H62 is the copper content of 60.5% to 63.5%, and the balance is the zinc content;

It has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy brazing and welding, corrosion resistance, but easy to produce corrosion cracking. In addition, the price is cheap, and it is a common brass variety that is widely used. H62 (ie four or six brass). The beta phase is much harder than the alpha phase at room temperature and can therefore be used for parts subject to higher loads. α+β two-phase brass can be hot worked above 600℃. α+β two-phase brass microstructure: α is a bright white solid solution, and β is an ordered solid solution based on CuZn. Inhibitory effect of strong electric field on cavitation of H62 brass during high temperature deformation.

Hot working temperature 650℃ ～850℃
Annealing temperature 600℃ ～700℃
The low temperature annealing temperature for eliminating internal stress is 270℃ -300 °C
