Investment Casting Essentials: How to Pick the Right Metal for Your Project


The investment casting company is a vital manufacturing process that enables the production of composite materials from several different metals. As a result, the investments are used in various sectors, including aerospace, automotive, energy, medical equipment and food.

In producing molten castings, the choice of material is essential to ensure the product’s quality and efficiency. With over 30 years of welding experience, this article discusses choosing the suitable mold to meet production requirements and improve productivity.  

This article discusses the selection of suitable materials from different perspectives. This includes the production of common materials for foundry casting, the application environment of the casting, the analysis of production costs, materials and dimensions, and the selection of casting manufacturers.

Application Environment of Investment Casting Products

Before choosing a metal material, it is essential to understand the environment in which the casting will be used.

Different application environments require different materials. In general, investment castings can be used in various environments, such as high and low temperatures, adverse environments, pressure and load conditions, wear resistance, etc.

The choice of suitable materials depends on the situation in which the product is used. If you need more clarification about the choice of materials for your project, you can contact our materials engineer, who will give you expert advice.

Precision casting features

Different Investment casting company have different properties and uses, such as strength, hardness, hardness, corrosion resistance, heat resistance, and many more. We briefly introduce the properties of some commonly used casting materials as follows:  

  • Carbon Steel 

Carbon steel is steel whose main component is carbon. The lower the carbon content, the better the hardness of the part, and the higher the carbon content, the greater the heat treatment and hardening ability. Carbon steel castings are relatively cheap and easy to handle.  

  • Alloy Steel

Alloy steel contains alloying elements such as manganese, nickel, chromium, molybdenum, vanadium, silicon, and boron. Alloy steel has excellent strength, hardness, durability, wear, corrosion resistance and toughness but can be more expensive and difficult to weld.  

  • Stainless Steel

Stainless steel is a silica salt that loses wax deposits. Casting system from a stainless steel alloy. Stainless steel is compact in size and strong in shape, and requires exact dimensions, so it is the most suitable choice for welding.

Stainless steel is a low-carbon steel containing 10.5% or more chromium for superior corrosion and mechanical properties.

Cost of Investment Casting Products 

Each Investment casting company has a monetary value limit. If we consider many factors, we must also consider the product’s price. Of course, the product’s value is also affected by many factors, such as raw material costs, production and processing technology, losses, durability and life expectancy.

Of course, the right product requires continuous testing and improvement, so the testing and evaluation of materials also influence the choice of powder materials.

Research and analysis of investment instruments

In mold testing, we can use experimental tests and micro-tests to evaluate essential factors, such as the mechanical properties of materials, corrosion resistance and heat resistance.  

In addition, we can simulate and predict content performance based on actual application requirements to monitor content performance in natural application environments.

Selection of Investment Casting Manufacturers

In addition to the above, it is essential to choose a reliable supplier. A good supplier must have a good reputation and a quality control system.

The quality and durability of the material can be ensured, and thus uncertainty is reduced. Strict qualification requirements are in place for inspection, performance evaluation and graduation.

Product inspection is in the supplier review, and the quality product is inspected and monitored throughout the process.   


Only one Investment casting company meets all requirements; choosing the most suitable material depends on the application and your needs.

When choosing materials, customers need to establish a trusting relationship with experienced engineers, which is very important in choosing suitable materials.
