FAQ
| What is the chemical composition of H62 brass strip? The typical chemical composition of H62 brass strip is about 60.5-63.5% Copper (Cu) and the remainder Zinc (Zn), with strict control over impurities like Lead (Pb) and Iron (Fe). |
| What is the equivalent grade of H62 brass strip in ASTM standard? H62 brass strip is equivalent to C28000 (Alloy 280 or Muntz Metal) in the ASTM/UNS system. |
| Can H62 brass strip be used for machining parts? Yes, H62 brass strip has fair machinability. It is suitable for stamping, bending, and forming operations, though it is not a free-machining grade like leaded brass. |
| What are the standard tempers available for H62 brass strip? H62 brass strip is commonly supplied in soft annealed (O), half-hard (H02), hard (H04), and spring hard (H08) tempers to meet different mechanical property requirements. |
| Is H62 brass strip resistant to seawater corrosion? H62 brass strip offers good general corrosion resistance. However, for prolonged exposure to stagnant seawater, a dezincification-resistant (DZR) brass is recommended over standard H62. |
| 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. |
