What Is The Difference Between Brass H65 And H62?

h65 and h62 are ordinary brass, the content is different, h65 copper content 65 h62 copper content 62 balance of zinc

H65 brass performance between H68 and H62, the price is cheaper than H68, has good mechanical properties also has high strength and plasticity, can withstand cold and hot pressure processing, there is a tendency to corrosion rupture. h65 brass is used to make small hardware, daily necessities, screws and other manufactured parts.

Material introduction

H65 brass is commonly used for H65 brass sheet, H65 brass strip, H65 brass tube, H65 brass rod.

Main characteristics

Through brass, has good mechanical properties, good plasticity in the hot state, plasticity in the cold state can also be, good machinability, easy brazing and welding, corrosion resistance, but easy to produce corrosion rupture. In addition the price is cheap and it is a widely used variety of general brass. h62 (i.e. four-six brass) The β-phase is much harder than the α-phase at room temperature, so it can be used for parts with larger loads. α+β two-phase brass can be hot worked above 600℃. α+β two-phase brass microstructure: α is bright white solid solution, β is CuZn-based ordered solid solution.

General use

Can do all kinds of deep drawing and bending manufacturing of stressed parts, such as pins, rivets, washers, nuts, conduits,, barometer springs, screens, radiators
