Performance comparison of brass tubes

1, H59 ordinary brass tube; The price is the cheapest, the strength and hardness are high and the plasticity is poor, but it can still withstand the pressure processing well under heat treatment, the corrosion resistance is general, and other properties are similar to H62. Used for general machine parts, welding parts, hot stamping and hot tying parts.

2, H62 ordinary brass tube; It has good mechanical properties, good plasticity in hot state, plastic can also be in cold state, good machinability, easy brazing and welding, corrosion resistance, but easy to produce corrosion rupture. In addition, the price is cheap and is a common brass variety used by repeat offenders. Used for all kinds of deep drawing and bending parts, such as pins, rivets, washers, nuts, conduits, barometer springs, screens, radiator parts, etc.

3, H63 national brass pipe; Suitable for cold pressure processing, suitable for welding and brazing. Easy to polish, is the main alloy for drawing, tying, bending and other forming. Round rolls for screws, pickling, etc.

4, H65 national brass pipe; The performance is between H68 and H62, the price is cheaper than H68, but also has higher strength and plasticity, can withstand cold and hot pressure processing well, and has the tendency of corrosion rupture. Used for hardware, daily necessities, small springs, screws, rivets and mechanical parts.

5, H68 national brass pipe; It has extremely good plasticity (the best in brass) and high strength, good cutting performance, easy to weld, non-stable to general corrosion, but easy to crack. It is the most widely used variety of common brass. For complex cold and deep drawing parts, such as radiator shell, conduit, bellows, shell, gasket, etc.
