Investment casting has an unlimited selection of alloys and is the most common metal forming method. Designers are not limited to any specific alloy, as the investment casting process allows for easy replacement of alloys using the same tools. Each alloy has unique mechanical properties, including varying degrees of hardness, corrosion resistance, conductivity, and ductility.

Qingdao Qiangsenyuan Technology Co., Ltd. is a professional manufacturer and supplier of special alloy casting parts. Our products are manufactured according to industry standards or strict customer specifications. Our products have the following special alloys to choose from: cobalt based alloys, nickel based alloys, and special stainless steel.

Investment Casting Cobalt Based Alloys

Cobalt based alloys are investment casting materials that are alloyed with nickel, chromium, and tungsten. Known for its high strength, heat resistance, and wear resistance. They naturally have antioxidant properties and high melting points, achieving optimal performance in chemical and corrosive environments. Cobalt based alloy castings are suitable for various fields such as nuclear power, petrochemicals, electricity, batteries, glass, light industry, food, etc. It has wear resistance, corrosion resistance, oxidation resistance, and high temperature resistance characteristics. Commonly used products include valve cores, valve seats, shafts, shaft sleeves, pump components, glass, battery molds, nozzles, and cutting tools.
Common models of cobalt based alloys:
Stellite series alloys: Stellite1、Stellite4、Stellite6、Stellite8、Stellite12、Stellite20、Stellite21、Stellite31、Stellite100, etc.
Tribaloy series alloys: T400, T800, etc.
Haynes series alloys: Haynes25, Haynes188, etc.

Investment Casting Nickel Base Alloy

Used for precision casting parts, which will be used for high demand applications in oil and gas, medical, nuclear power, aerospace and Arms industry. This material has a wide range of uses, has corrosion resistance, and can withstand high temperatures. Nickel alloy casting materials include stainless steel, nickel chromium alloy, nickel copper alloy, etc. It has excellent high temperature resistance, oxidation resistance, corrosion resistance in the weld affected zone, and good long-term thermal stability and processability, and is widely used in harsh industrial environments such as Chemurgy, nuclear facilities, biological pharmacy, etc.
Common models of nickel based alloys:
Incoloy alloys: Incoloy925, Incoloy956, Incoloy901, Incoloy825, Incoloy20, Incoloy903, Incoloy330, Incoloy28, Incoloy840, Incoloy800, Incoloy890, Incoloy926, etc.
