For many product designers and manufacturers, aluminum is the metal of choice for many applications. Aluminum investment castings are stronger than many steels, providing a means to achieve weight reduction goals without compromising product integrity.
Our capabilities, expertise and attention to detail have made us a leader in aluminum investment casting. Demanding customers in the aerospace, defense, medical and automotive industries continue to trust us to produce high-quality aluminum castings weighing up to 50 lbs (23 kg) for their most critical applications.
Casting a wide range of aluminum alloys
Tensile strength is the main requirement in many applications, but others require good weldability, excellent fatigue properties or high levels of corrosion resistance. Our expertise covers an extremely wide range of aluminum alloys, and we can help customers understand which aluminum alloy best meets property, performance and cost requirements.
Benefits of Choosing Aluminum Investment Castings
Aluminum castings can save weight compared to other metals, but the advantages don't stop there. With its high flowability, molten aluminum flows easily into thin-walled parts inside the mold. Because aluminum can reproduce intricate features and fine details, it is well suited to the investment casting process.
Aluminum castings are generally less expensive and more energy efficient. Aluminum typically processes much faster than iron castings and has a lower melting point; iron alloys melt at 2,800 degrees Fahrenheit, while aluminum melts at 1,100 degrees Fahrenheit.
Additionally, aluminum is corrosion resistant so no coating is required. If a specific finish is required for aesthetic or performance reasons, options include anodizing, powder coating, e-coating and paint.
