Products Description
H62 brass is a copper-zinc alloy, with copper as the primary component (60.5%–63.5%) and zinc comprising the remainder. It is classified as an alpha-beta brass, meaning it contains both the alpha and beta phases of the Cu-Zn solid solution. This dual-phase microstructure provides a balance of strength, ductility, and corrosion resistance, making H62 brass ideal for a wide range of applications.
The "H" in H62 refers to the pinyin initial for "Huang" (meaning yellow in Chinese), while "62" denotes the average copper content. H62 is categorized as a common brass, but it can also be alloyed with trace elements to enhance specific properties.

How Does H62 Brass Compare to Other Brass Alloys?
H62 offers a great balance of strength and ductility in your brass. Why would you choose H70 over H62? It's going to be more ductile. It's going to be easier to cold work. On the other hand, if you pick H59, you'll get a stronger brass, but it won't have the ductility that H62 does. H62 brass is in the middle. It gives you a great combination of strength and workability. That's why it's such a good all-around brass for most of us.
FAQ
| Q: What is the maximum width and thickness for H62 brass strip? H62 brass strip is typically available in widths from 10mm to 600mm and thicknesses from 0.1mm to 6.0mm, depending on the manufacturer's capabilities. |
| How does the price of H62 brass strip compare to C26000 (70/30 brass)? Generally, H62 brass strip (60% Cu) is more cost-effective than C26000 brass strip (70% Cu) due to its lower copper content, making it a popular choice for many industrial applications. |
| Can H62 brass strip be welded or soldered? Yes, H62 brass strip has excellent solderability and good brazeability. Gas tungsten arc welding (GTAW) is recommended for welding H62 brass. |
| What surface finishes are available for H62 brass strip? Common surface finishes for H62 brass strip include mill finish, bright finish, brushed (satin) finish, and polished finish, depending on aesthetic and functional needs. |
| What are the key mechanical properties of half-hard H62 brass strip? Half-hard (H02) H62 brass strip typically has a tensile strength of 410-450 MPa, a yield strength of 320-370 MPa, and an elongation of 20-30%. |
| Does H62 brass strip require any special packaging for export? Yes, for export, H62 brass strip should be packaged with VCI paper, edge protection, securely palletized on fumigated wood, and wrapped in waterproof film to prevent corrosion and damage. |
| Is H62 brass strip suitable for making springs? Yes, when supplied in spring hard (H08) temper, H62 brass strip can be used to manufacture springs, contacts, and other components requiring high elastic limits. |
| What is the density of H62 brass strip? The density of H62 brass strip is approximately 8.47 grams per cubic centimeter (g/cm³). |
