ZL104 aluminum alloy is a high-strength aluminum alloy material. Can be used to manufacture grinding tools.
Material name: ZAlSi9Mg: Density: 2.65g/cm ³ Standard: GB/T 1173-1995Mg
Scope of application: Can be strengthened by heat treatment. Its strength is higher than that of alloys such as ZL101.ZL102. The casting performance of this alloy is good, with no tendency towards hot cracking, high airtightness, and reduced wire shrinkage; But the tendency to form pinholes is greater, and the melting process is more complex. The corrosion resistance of the alloy is good, but its machinability and weldability are average.
