For many manufacturers, utilizing investment casting with aluminum alloys offers significant benefits over other metals. One of the biggest potential benefits is that aluminum is about one-third the weight of steel. It is also completely impermeable to odor and light, and its oxide-coated surface is highly resistant to corrosion. Aluminum is an excellent conductor of heat and electricity, while being far lighter than other metals, such as copper. It is extremely ductile, making it easy to work with, plus aluminum is 100% recyclable and highly sustainable, requiring less energy and almost no waste.
