Investment castings can be used to make a wide range of products and prototypes. It’s important when using investment castings to make your product or prototype to use the right materials. Aluminum alloy, titanium alloy, steel, and superalloys are all quality materials used. Let’s take a deeper look into each one.
Aluminum alloy is the most used material in investment castings, especially in the fields of aerospace, avionics, electronics, military command equipment, and pump and valve applications. Improved strength and premium quality aluminum-silicon-magnesium alloy castings means casters can now offer castings for demanding applications, such as airframe components.
Titanium alloy castings are made for products that require high fracture toughness and metallurgical integrity. Titanium golf club heads form a substantial part of the titanium investment casting market.
The variety of steels used in investment castings have increased drastically as designers and engineers have realized its durability and potential. From bicycle can forks to gearbox parts for automotive applications, to various gears and cam components, to even golf club heads, steel covers them all.
Superalloys are replacing sheet metal. Not only are they are more cost-effective, but they also provide a high rigidity monolithic component with superior service characteristics.
