H90 brass is a copper-zinc alloy with a copper content of 90%, so it is also called gold medal brass. It has the following characteristics and uses:
Characteristics
Mechanical properties: H90 brass has good mechanical properties, including high tensile strength (≥390 MPa) and elongation (≥3%).
Pressure processing performance: It is easy to perform hot and cold pressure processing, such as forging, cold drawing, rolling, etc.
Surface treatment performance: The surface treatment performance is good and suitable for metal plating and enamel coating.
Corrosion resistance: It has high corrosion resistance in the atmosphere and fresh water, but the corrosion rate in seawater may reach 0.1 mm/a.
Electrical conductivity and thermal conductivity: It has good electrical conductivity and thermal conductivity, suitable for electrical and thermal conduction applications.
Chemical composition:
Cu: 88.0-91.0%
Ni: 0.5%
Fe: 0.10%
Pb: 0.03%
Zn: Residue
Impurities: 0.2%
Applications
