Inconel 625 Nickel Based Alloy Investment Casting Product

As an investment casting foundry and original manufacturer in China, RMC Casting Foundry could pour nickel based alloy castings as per your drawings and requirements with full CNC machining services.

The investment casting is also called precision casting because it have much better surface and higher accuracy than any other casting process. Especially for the silica sol casting process, the finished castings could reach the CT3 ~ CT5 in geometrical casting tolerance and CT4 ~ CT6 in dimensional casting tolerance. For the casings produced by investment, there will be less or even no need to make the machining processes. To some extent, the investment casting could replace the rough machining process.

Almost most of the ferrous and nonferrous metal and alloys could be cast by investment casting process. But, at our lost wax casting foundry, we mainly cast nickel base alloys, cobalt base alloys, carbon steel, alloy steel, stainless steel, super duplex stainless steel, gray cast iron, ductile cast iron, aluminium alloys and brass. Additionally, certain applications require the use of specialized other alloys used primarily in harsh environments. These alloys, such as Titanium and Vanadium, meet the additional demands that might not be achieved with standard Aluminum alloys. For example, Titanium alloys often are used to produce turbine blades and vanes for aerospace engines. Cobalt-base and Nickel-base alloys (with a variety of secondary elements added to achieve specific strength-strength, corrosion-strength and temperature-resistant properties), are additional types of cast metals. 

Nickel-based alloy refers to a high alloy with nickel as the matrix (generally greater than 50%) and copper, molybdenum, chromium and other elements as alloying elements. The main alloying elements of nickel-based alloys are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium and so on. Among them, Cr, Al, etc. mainly play an anti-oxidation effect, and other elements have solid solution strengthening, precipitation strengthening and grain boundary strengthening. Nickel-based alloys mostly have austenitic structure. In the state of solid solution and aging treatment, there are also intermetallic phases and metal carbonitrides on the austenite matrix and grain boundaries of the alloy.

Nickel-based alloys have high strength and good oxidation resistance, corrosion resistance and high temperature resistance in the range of 650 to 1000°C. Nickel-based alloy is a common high-temperature resistance alloy. Nickel-based alloys are subdivided into nickel-based heat-resistant alloys, nickel-based corrosion resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys according to their main properties. Nickel-based superalloys, iron-based superalloys and nickel-based superalloys are collectively referred to as high-temperature alloys. Therefore, nickel-based superalloys are referred to as nickel-based alloys. Nickel-based superalloy series materials are widely used in aviation, aerospace, petroleum, chemical, nuclear energy, metallurgy, marine, environmental protection, machinery, electronics and other fields. The grades and heat treatment methods selected for different mechanical parts will be different.

Nickel-based alloys are generally cast through an investment casting process. The common grades of nickel-based alloys for casting are as follows:
1) Ni-Cr-Mo alloy, Hastelloy series C-276, C-22, C-2000, C-4, B-3
2) Ni-Cr alloy: Inconel 600, Inconel 601, Inconel 625, Inconel 718, Inconel X 750, Incoloy 800, Incoloy 800H, Incoloy 800HT, Incoloy 825;
3) Ni-Cu alloy, Monel 400, Monel K500
