Investment casting China foundry provides manufacturers with a wide list of material choices depending on the required investment casting properties. Here are some of the standard materials investment foundries in China use:
Stainless steel is a corrosion-resistant alloy consisting of steel, chromium, and nickel. The combination of these metals results in a strong, durable, and rust-resistant material. After the investment casting process, stainless steel components are commonly used in medical, automotive, and aerospace applications. This is because they can withstand extreme conditions and offer excellent strength.
China's carbon steel castings are made using carbon steel, a steel variant that features a proportion of carbon. Usually, carbon steel comes at a lower cost. After casting, carbon steel is used in applications that do not require stainless steel's high corrosion resistance, such as in construction and the manufacture of machinery.
Often, to improve on the properties of carbon steel, alloying elements such as manganese, boron, or nickel are added. The resulting alloy steel is then used to manufacture components that require higher durability and strength in extreme conditions. Typically, such applications are predominant in the automotive and aerospace industries.
Usually, copper alloys are made by mixing copper with other metals, such as zinc or tin. Often, brass is made when copper is mixed with zinc, while bronze is the result of mixing copper with tin. Often, these alloys are selected for their excellent corrosion resistance properties and electrical conductivity. Usually, copper alloys are highly valued in electronics, marine, and architectural applications.
Conventionally, iron alloys for investment casting include malleable and ductile cast iron. Basically, these cast iron variants are favored for their outstanding wear resistance and for being cost-effective. Conventionally, ductile iron (also known as spheroidal graphite iron) contains small amounts of alloying elements such as magnesium. Therefore, it assumes a unique microstructure that enhances its strength and resilience. Also, for its strength and durability, ductile cast iron is commonly used in components such as gears and shafts. On the other hand, Malleable iron has also been used in applications requiring toughness and, at the same time, good machinability. Commonly, they include automotive parts and machinery components.
Customarily, nickel-based alloys are produced by mixing nickel with other metals such as chromium or molybdenum. They are specifically designed to withstand high temperatures, oxidation, and corrosion. Hence, ideal for usein aerospace components, gas turbine frameworks, and other applications exposed to extreme environments.

Basically, investment casting in Chinese foundries offers international clients a wide selection of materials. More importantly, these materials are suitable for use in medical applications.
Often, in industries, machinery components are subjected to heavy loads and harsh operating conditions. Therefore, it is vital when manufacturing them to ensure they are the least worn out. Ideally, investment casting provides a method for creating durable parts. Standardly, these parts include pumps, valves, and gearbox components. In addition, chinese foundries produce these castings using a broad spectrum of alloys. Hence, making it easy for industries to find suitable castings for their specific needs.
Customarily, this industry commonly operates in highly demanding environments, therefore requiring components that can withstand corrosion and extreme pressures. Also, investment casting is utilized to produce critical parts such as pump housings, valve bodies, and piping components. Further, Chinese foundries provide international buyers with high-quality castings made from either stainless steel or nickel-based alloys. They are both capable of withstanding harsh chemical exposures.
For clients to meet the diverse needs of their customers, Chinese suppliers offer various customizing options for their investment castings. Below are the common types:
Chinese foundries provide their buyers with a large selection of materials for their investment castings. In most cases, it is based on their preferredproject requirements. Normally, the materials available are such as stainless steel, carbon steel, titanium, and nickel-based alloys. Normally, they can provide these materials in varying grades to ensure they meet the required standards. In addition, each material offers unique benefits that make them ideal for use in specific projects.
Conventionally, to enhance the appearance and performance of investment castings, Chinese foundries apply various surface finishing methods. Basically, these methods go beyond improving aesthetics to improving functional characteristics. Normally, they include the following common techniques: polishing, sandblasting, and coating. Usually, in addition to the aesthetic value, these techniques also offer protection against corrosion and wear. This makes them ideal for use in investment castings destined for use in harsh environments.
Often, highly demanding industries such as aerospace and medical require components with tight tolerances and specific technical features. Usually, China investment casting foundries are capable of catering to these requirements by closely working with their customers to define and produce the desired tolerances.
