ALUMINUM CASTING SERVICES

What is Aluminum Casting?

Aluminum casting is a manufacturing process where molten aluminum or aluminum alloys are poured or forced into a mold to create desired shapes. Aluminum offers advantages like lightweightness, corrosion resistance, and good thermal conductivity. Its high strength-to-weight ratio allows for the design of robust yet lightweight structures, crucial for reducing energy consumption and improving performance. Additionally, its non-magnetic properties make it perfect for applications in sensitive electronic devices and environments where magnetic interference must be avoided.

Two common aluminum alloy casting techniques, gravity die casting and pressure die casting, find applications in a variety of industries, including automotive, aerospace, marine, consumer electronics, railway, and many more. Aluminum can also be cast by investment casting for complex parts, especially those with intricate internal structures, requiring very tight tolerances (CT4-CT7). Compared to investment casting, die casting delivers high-volume production with faster cycle times.

Our Aluminum Alloy Expertise

At Simis, we routinely cast aluminum alloys well-suited for a wide range of applications due to their excellent castability, fluidity, and corrosion resistance. These alloys offer a versatile combination of mechanical properties, and our optimized casting processes and heat treatment services further enhance their strength, hardness, and ductility.

Common AlSi alloys for gravity die casting include:

A356: Excellent castability, good strength, and good corrosion resistance; often used for automotive structural components, aircraft parts, and impellers.
A357: Similar to A356 but with higher magnesium content for improved strength and heat treatability; used for high-performance applications.
A380: Good fluidity and castability, good strength, and good corrosion resistance; used for general-purpose castings and is often the most widely used alloy for pressure die casting.
A413: Excellent fluidity and castability, superior corrosion resistance compared to A380; used for general-purpose castings, especially where thin walls or intricate details are required.

Common AlSi alloys for pressure die casting include:

A380: Excellent castability, good strength, and good corrosion resistance; the most widely used pressure die casting alloy.
A383: Improved die filling characteristics and hot tearing resistance compared to A380; suitable for more complex parts.
A360: Excellent corrosion resistance and good strength; suitable for thin-walled castings.

While the above list highlights common aluminum alloy grades we cast, it is not exhaustive. We can work with other alloys based on specific project requirements.
