A wide variety of metal materials can be applied in MIM process. Metal powder with various chemical composition, particle sizes and shapes will determine final MIM parts properties. ZCMIM main MIM metal materials are classified into categories as following:
Ferrous alloys: steel, stainless steel, tool steel, low alloy steel, iron-nickel alloy, special ferrous alloys like Invar and Kovar.
Tungsten alloys: tungsten-copper, tungsten heavy alloys.
Nickel alloys: nickel, nickel-base superalloys.
Molybdenum alloys: molybdenum, molybdenum-copper.
Titanium alloys: titanium, titanium alloys
Hard materials: cobalt-chromium, cemented carbides(WC-Co), cermets(Fe-TiC)
Special materials: aluminum, precious metal, copper and copper alloys, cobalt-based alloys, magnetic alloys (soft and hard),shape-memory alloys
Most alloys composition are copied from standard handbook formulations, but it cannot be ignored that long-term anneal in sintering process will degrade alloy properties, since most alloys were created and developed in casting technology. So ZCMIM utilize modified chemistry way customized to MIM technology, in order to guarantee MIM parts physical and chemical properties.
Such as 316L alloy composition (Fe-19Cr-9NI-2Mo) is wildly applied in reason of its corrosion resistance and combined strength properties. Extra additional chromium in alloy composition will make sintering process easily, so this alloy provides attainable superior properties with this alternative metal manufacturing method.
Custom metal powder can be fabricated with additional cost once composition is unavailable. There is no doubt that ZCMIM will satisfy your any custom material requirement in most cost-effective price.
