Aluminum Investment Casting
Aluminum Investment Casting: Aluminum has a wide array of favorable characteristics that make it a top alloy choice for several industries that require intricate, lightweight investment castings with good mechanical properties. These alloys have great fluidity, allowing for the casting of extremely thin walls with a high level of precision. Their low density makes them a perfect fit for the aerospace industry, where weight and detail are critical. Aluminum’s thermal conductivity also makes it an excellent choice for applications such as heat sinks or electronic enclosures. These alloys yield smooth as-cast surface finishes, and are easily anodized or plated to give your castings the finish they require for any application. In addition, aluminum is corrosion resistant with a high machinability rating.
