Ironbound Castings Aluminum Alloy Castings
Ironbound Castings pours a full range of aluminum casting alloys for structural, mechanical, and fluid system applications. From A356 general-purpose castings to 535 for high-corrosion-resistance applications, our aluminum castings offer excellent strength-to-weight ratio, machinability, and surface finish.
All aluminum castings are produced with full ASTM B26 chemistry and mechanical property certification. In-house machining, dimensional inspection, and heat treatment support are available to deliver finished, ready-to-install parts.
A356 / A356-T6
The most widely used aluminum casting alloy — excellent castability, good mechanical properties, and excellent machinability. T6 heat treatment available for maximum strength.
319 ALLOY
A319 for good strength and pressure tightness in pump housings, valve bodies, and manifolds. Excellent resistance to hot cracking and good machinability.
535 / ALMAG 35
High-magnesium aluminum alloy for superior corrosion resistance in marine, chemical, and food-processing applications where excellent as-cast finish is required.
Sizes & Applications
Ironbound Castings produces aluminum castings from a few ounces to over 150 pounds using green sand molding. Common applications include pump impellers, volute housings, gearbox covers, structural brackets, instrument housings, and aerospace structural parts.
Our in-house pattern shop builds and maintains all aluminum casting patterns, enabling rapid prototype-to-production transitions and quick engineering change incorporation. Contact us with your drawing and alloy specification for a prompt quote.
