What We Deliver in Aluminum Casting

Aluminum sand casting requires precise control of temperature, alloy composition, and mold design to produce reliable components. We cast alloys that meet ASTM B26/B26M standards for high-integrity applications. Our work spans automotive, aerospace, railing hardware, marine, and structural projects where weight reduction and durability are critical. The excellent strength-to-weight ratio of aluminum makes it ideal for parts that must be both strong and light. We pour alloys engineered for T6 heat treatment to increase strength, as well as castings that offer excellent machinability and weldability. Our components deliver dimensional stability and corrosion resistance in applications ranging from engine blocks to structural hardware. Testing is built into our process to ensure every casting meets strict customer specifications. We use mechanical and chemical analysis to verify alloy composition and performance characteristics. This level of control ensures the parts leaving our shop are ready for the job they were designed to do.

Aluminum Alloys We Cast

We can pour multiple aluminum alloys, each selected for specific performance requirements. Our range covers general industrial work to aerospace-grade specifications and other performance requirements for challenging applications.

319.1 & SR-319 Aluminum: Versatile alloys used for automotive engine blocks, cylinder heads, and transmission housings. These grades offer good castability, machinability, and heat-treatability, resulting in improved mechanical properties.

356.1 & A356.2 Aluminum: Our primary aluminum casting alloys for general industrial and structural applications. A356 is heat-treatable to T6 and provides excellent strength, corrosion resistance, and weldability for a wide range of uses.

713.1 Aluminum (Tenzaloy): A specialized alloy for applications requiring specific performance characteristics. It delivers reliable strength and dimensional accuracy for demanding industrial components.

535 Aluminum (Almag35): Marine and structural alloy engineered for superior corrosion resistance in harsh environments. This grade is specified for parts exposed to saltwater and corrosive atmospheric conditions.

ZA-12 (Zinc-Aluminum Alloy): An advanced zinc-aluminum alloy known for its exceptional strength, wear resistance, superior machinability, and low casting shrinkage. It is an excellent choice for demanding applications such as bearings, bushings, gears, wear plates, and hydraulic components where durability and precision are critical.

Component Specifications

Our aluminum sand casting capabilities accommodate a broad range of part sizes. We produce components weighing from 0.01 lbs. to 100 lbs., with a maximum part length of 3 feet.

Advantages of Our Aluminum Casting Services

Working with Lincoln Foundry means working with a foundry that understands both the material and the craft. We combine metallurgical knowledge with time-tested sand casting techniques to produce aluminum components that perform.

Lightweight Strength: Aluminum castings offer an exceptional strength-to-weight ratio, making them the material of choice for aerospace, automotive, and defense applications. Our alloys deliver structural integrity without unnecessary weight.

Corrosion Protection: Aluminum forms a natural oxide layer that resists corrosion in most environments. We cast specialized marine-grade alloys such as Almag35, which provide even greater protection in saltwater and harsh atmospheric conditions.

Heat Treatment Capability: Many of our aluminum alloys can be heat-treated to T6, significantly increasing their tensile strength and hardness. This allows us to tailor the mechanical properties of a casting to meet demanding load and stress requirements.

Superior Machinability and Weldability: Aluminum is among the most workable casting metals. Our alloys machine cleanly and weld reliably, making post-casting modifications and assemblies straightforward and cost-effective.

How Patterns Drive Aluminum Casting Accuracy

Quality aluminum casting services begin with a properly engineered pattern. Our pattern shop builds these master copies to client specifications using wood, plastic, or metal materials chosen for precision and durability. Each pattern is fitted with the gating and riser configuration necessary to control metal flow during the pour. This design work ensures molten aluminum fills the mold, producing a dense casting free of porosity and defects.

Three Generations of Foundry Experience

Lincoln Foundry is a family-owned operation with over 50 years of experience casting non-ferrous metals. Our approach has always been direct and hands-on, because shortcuts don't produce quality. We believe foundry work is honest work that deserves respect, and we treat every casting with the care it requires. The hard jobs matter most to us. That mindset keeps us focused on doing things right, even when the easier path is available. Every mold, every pour, and every grind is work that supports the industries building our future. This commitment to craftsmanship is what defines a blue-collar foundry, and it's what we put into every aluminum component we cast.

Industries Powered by Our Aluminum Castings

Aluminum's unique properties make it indispensable across a wide spectrum of commercial fields. We supply expertly crafted aluminum components to the following markets:

Aerospace & Defense
For vital aviation and military systems, we cast robust yet low-density aluminum alloys. These materials deliver the crucial balance of durability and minimal mass required for the most demanding uses, including airframe structures and powertrain components.
Naval/Marine
In punishing marine settings, our specialized aluminum alloys are formulated to resist saltwater degradation. Their exceptional corrosion resistance, combined with their low density, makes them the ideal choice for maritime fittings, enclosures, and key structural elements on vessels.
Industrial & Manufacturing
Industrial machinery benefits from aluminum's combination of robustness, leak-proof integrity, and mass reduction. Our foundry creates long-lasting parts such as pump enclosures, valve assemblies, and equipment supports designed to boost operational effectiveness.
Automotive & Transportation
Vehicle manufacturers employ our aluminum castings to achieve substantial mass savings and manage heat effectively. We supply pivotal parts, including powertrain casings, cylinder heads, and chassis elements, that contribute to improved mileage and handling.
Electrical & Utilities
With its capacity to efficiently conduct heat and electricity, aluminum is fundamental to the power and utilities field. We furnish castings for items like protective enclosures for electronics, thermal management fins, and hardware for the energy grid.
Architectural & Construction
Aluminum is a top choice for building applications due to its lasting nature, resistance to weathering, and clean aesthetic. It is frequently specified for fixtures, ornamental features, and support pieces to provide structural integrity while minimizing loads.
Consumer & Decorative Products
Because it can be finished to a high standard and is easy to handle, aluminum is frequently selected for premium retail items. Our castings are used for device casings, recreational gear, and ornamental fittings that merge elegant form with enduring substance.
