Industries that use aluminum castings
FERR specializes in providing precision-machined aluminum components for industries with demanding requirements, incorporating lightweight design and exceptional durability into our products.
Automotive
We supply high-precision engine components, electric vehicle motor housings, and structural parts, all of which meet stringent automotive safety standards.
Industrial & Fluid Control
Our valve bodies, pump housings, and fittings are engineered for high-pressure, harsh environments, delivering zero-leak performance and exceptional corrosion resistance.
Telecom & Power
The complex housings and heat sinks we manufacture offer excellent thermal conductivity and weather resistance, making them ideal for outdoor telecommunications and power grid infrastructure.
In-House Machining for OEM aluminum Casting Parts
Every aluminum casting component we produce is machined, drilled, tapped and cleaned in-house. Products leaving our factory are dimensionally accurate and ready for immediate use on your assembly line.

NDT Inspection for Cast aluminum Parts
Every aluminum casting part is inspected before shipment — surface porosity, cold shuts, shrinkage defects, and dimensional deviations are all caught in-house, so defective parts never reach your production line.
X-RAY
Reveals internal shrinkage cavities, porosity clusters, and misruns inside complex aluminum casting geometries that surface inspection cannot reach.
Ultrasonic Testing
Measures wall thickness and detects subsurface voids or inclusions in large or heavy-section aluminum casting parts — non-destructively, leaving the part fully intact.
Advantages Of Our Aluminum Casting Parts
Drawing on our extensive manufacturing experience, we offer aluminum castings with higher density, a more compact structure, and lower internal porosity.

Our Aluminum Casting Manufacturing Approach
We combine degassed aluminum, gravity-controlled solidification, and precision post-processing into one integrated workflow — so parts arrive dimensionally accurate, structurally sound, and ready to install.
Engineering Design & Pattern Setup
Our engineers optimize the casting geometry using Sand Casting or Permanent Mold technologies. We focus on critical factors such as directional solidification, shrinkage allowance, and riser placement. Before pouring, premium aluminum ingots (e.g., A356, A319) are refined and degassed to eliminate hydrogen and impurities, ensuring a clean, stable melt.
Controlled Gravity Casting Process
Unlike high-pressure methods, our Gravity/Sand Casting process relies on controlled metal flow to minimize turbulence and air entrapment. By monitoring pouring temperatures and cooling rates, we ensure a fine grain structure. This process is ideal for producing heavy-duty power fittings and components with thick cross-sections that require maximum mechanical strength.
T6 Heat Treatment & Precision Machining
Post-casting, parts undergo T6 Heat Treatment (Solution & Aging) to significantly enhance tensile strength and hardness—a critical advantage of gravity casting. After removing runners and risers, tolerance-sensitive areas are processed in our high-speed CNC centers to meet exact specifications, ensuring an "easy-to-install" experience.

FAQ
We specialize in delivering fully finished aluminum castings ready for immediate assembly. Drawing on 20 years of expertise in custom metal components, we offer end-to-end solutions. This goes beyond basic casting to include high-precision CNC machining, stringent surface treatments (such as anodizing or corrosion-resistant coatings), and rigorous final inspections. The valve bodies, industrial fittings, or enclosures you receive from us can go straight onto your production line.
We adhere to rigorous craftsmanship standards and a comprehensive quality control system. From spectral analysis of raw materials to X-ray non-destructive testing (NDT) for porosity, and precision coordinate measuring machine (CMM) inspections, we ensure that every casting meets your most stringent tolerance requirements and is free of defects.
Absolutely. Whether it’s the high corrosion resistance required for industrial piping systems, the exceptional thermal conductivity needed for telecommunications heat sinks, or the high strength-to-weight ratio required for structural components, we can precisely match and cast the specific aluminum alloy grade you need.
Typically, mold design and approval of the first article sample (FAS) take 3 to 5 weeks, depending on the casting’s complexity.
