MIM- Aluminium alloy
Materialintroduction: The MIM process is used to producehigh-strength aluminum alloy products, the mechanical properties of thematerial are close to the plate, and it does not contain Sn and otherstrength-reducing elements. It is advantageous for the processing of small andcomplex products of aluminum alloy.
