Choosing the Right Material for Investment Casting

Author: Date Published: Jul 24,2023

What is Investment Casting?

Investment casting is a metalworking process that involves creating a shape, 

called the investment, out of wax or other materials. 

The investment is then coated with refractory material and heated to create a hollow mold. 

Molten metal is poured into the mold, and once it has solidified, the mold is broken away to reveal the final product.

It is essential to use suitable materials for investment casting since the properties of the material affect the quality

and performance of the final product. The wrong material can reduce the strength of the part, 

decrease dimensional accuracy, or even cause the part to fail entirely. 

Benefits of using investment casting in different industries

Investment casting is used in various industries due to its many benefits.

In the Aerospace Industry, investment casting is used to create parts for jet engines and turbines. 

The process can produce parts with high accuracy and complex geometries,

making it ideal for producing parts with intricate internal cooling passageways or turbine blades. 

The automotive industry also utilizes investment casting to create parts such as engine mounts, 

exhaust manifolds, and transmission components.

Materials Used in Investment Casting

Investment casting can use a wide range of materials, including steel, aluminum, brass, and others. 

The material used depends on the specific requirements of the part. 

The types of materials used in investment casting can be grouped into three categories: 

ferrous alloys, non-ferrous alloys, and refractory materials. Ferrous alloys include steel, iron, and stainless steel

Non-ferrous alloys include aluminum, brass, bronze, and copper. 

Refractory materials include ceramic materials that can withstand high temperatures. 

Each material has its unique properties, including strength, ductility, 

toughness, and resistance to corrosion, wear, and temperature.

It is essential to select the right material for the part to ensure that it meets the specific requirements. 

Factors Considered When Selecting Investment Casting Materials

When selecting materials for investment casting, several factors need to be considered,

including design requirements, component function and performance, production volume and cost, and environmental considerations. 


In conclusion, selecting suitable investment casting materials is essential

for ensuring the highest quality and performance of the final product.

By carefully considering the specific requirements of each project and the properties of each material,

it is possible to produce parts that meet the highest standards.
