High Quality Multifunctional Brass Wire Metal Copper Wire

Characteristics and uses

Grade	Characteristics	Use
H70/C2600	Excellent plasticity, high strength, good cutting processability, good welding and corrosion resistance	Heat exchangers, paper tubes, machinery, electronic parts
H68/C2680	The performance is very similar to H70, but there is a tendency of "cracking" during cold working.	Used for complex cold stamping and deep drawing parts, such as bellows, cartridge cases, etc.
H65/C2720	Has good mechanical properties and can withstand hot and cold processing	Make small hardware, daily necessities, screws and other parts
H63/C2720	It has good mechanical properties, good plasticity in hot state, good machinability, weldability and corrosion resistance.	Various deep extension and bending force-bearing parts, such as pins, nuts, barometer springs, heat dissipation, and ring parts
H62/C2720	It has good mechanical properties, good plasticity in the hot state and good plasticity in the cold state. It has good machinability, is easy to braze and weld, and is corrosion-resistant, but it is prone to corrosion and cracking.In addition, it is cheap and is a common brass variety that is widely used.	Can be used to produce various deep drawing and bending stress-bearing parts, such as pins, rivets, washers, nuts, conduits, barometer springs, screens, radiator parts, etc.
H59/C2800	The cheaper brass has high strength, hardness and good plasticity, but it can still withstand pressure processing well in the hot state. It has average corrosion resistance and other properties are similar to H62.	Can be used to make various deep drawing and bending stress-bearing parts, such as pins, rivets, washers, nuts, conduits, barometer springs, screens, radiator parts, etc.
