Investment Casting of Different Metals

Investment Casting of Different Metals

Precision investment or lost wax castings can be produced with a wide range of metals and their alloys. At precision investment casting foundry of RMC, normally we use the stainless steel, carbon steel, ductile iron, brass & bronze and other customized ferrous or non-ferrous metals.

Stainless Steel Investment Castings

The base chemical composition of stainless steel investment casting are chromium, nickel, and molybdenum (or "moly"). These three elements determine the casting's grain structure and mechanical properties and meanwhile play an important role in the casting's ability to combat heat, wear, and corrosion. Stainless steel has a minimum chromium content of 10.5%, making it more resistant to corrosive liquid environments and oxidation. However, this is not absolute. Stainless steel investment castings are "corrosion-resistant" when used in liquid environments below 1200°F (650°C) and "heat-resistant" when used above this temperature.

Carbon Steel Investment Castings

Carbon steel, alloy steel, and tool steel castings are used in many industrial areas. With numerous grades, steel and their alloys can be heat-treated to improve its mechanical properties such as yield strentgh and tensile strength and, adjust hardness or ductility to the engineer's application needs or desired mechanical properties.

Ductile Iron Investment Castings

Ductile iron offers design flexibility and reduced manufacturing costs versus welded fabrications and forgings. With diverse of advantages, ductile irons are widely used in numerous manufacturing industries, including agriculture, automotive, trucks, hydaulics, rail trains, and aerospace industries.

Copper-Based Investment Casting Alloys

Like many other alloys, copper and copper-based alloys can be formed into highly complex parts, making them ideal for the investment casting process. The costs of the raw materials is a very important factor because of they are so expensive comparing to the above metals.
