Premium Aluminum Bronze Sand Castings — Manufacturer & Exporter from India
Brass Parts India is a leading manufacturer and exporter of Aluminum Bronze Sand Castings, supplying high-integrity, precision-engineered castings to industries across the USA, UK, Europe, Australia, Canada, and the Middle East. With over three decades of experience in non-ferrous metal casting, we deliver parts that meet demanding engineering standards for marine, defence, oil & gas, valve, pump, and heavy engineering applications.
Our aluminum bronze sand castings are produced using the finest alloy compositions and well-controlled sand moulding processes, ensuring excellent mechanical strength, outstanding corrosion resistance, and long service life — even under the harshest operating conditions.
What is Aluminum Bronze Sand Casting?
Aluminum bronze sand casting is a traditional yet highly reliable casting process where molten aluminum bronze alloy is poured into a sand mould cavity to form complex shapes. Aluminum bronze alloys — typically containing 9–12% aluminum along with iron, nickel, and manganese — are renowned for their exceptional resistance to seawater corrosion, cavitation erosion, and biofouling. This makes them the preferred material choice for marine propellers, pump impellers, valve bodies, bushings, and wear plates.
Sand casting allows us to produce castings from a few kilograms to several hundred kilograms, with design flexibility not achievable through other methods. It is particularly suitable for low-to-medium volume production and complex geometries.

Key Applications of Aluminum Bronze Sand Castings
Our aluminum bronze sand castings serve a wide range of critical industries. In marine and shipbuilding, they are used for ship propellers, rudder fittings, sea cocks, stern tube bushings, and deck hardware. In the oil and gas sector, they form reliable valve bodies, pump casings, impellers, and subsea connectors. The defence industry relies on aluminum bronze for ammunition components, navy pump parts, and armoured vehicle bushings. In general engineering, they are found in heavy-duty bearings, worm gears, hydraulic fittings, and wear-resistant liners.
Our Technical Expertise
With 30+ years of hands-on experience, Brass Parts India combines metallurgical knowledge with modern manufacturing to deliver castings that consistently exceed customer expectations. Our in-house capabilities include spectrometric alloy verification, radiographic testing (RT), ultrasonic testing (UT), and dye penetrant testing (DPT) to ensure every casting meets specification. Our engineering team can review customer drawings, suggest design improvements for better castability, and produce first articles for approval before mass production begins.
We maintain a fully equipped pattern shop, sand testing laboratory, and dedicated quality control area, enabling us to offer complete casting solutions from raw alloy to finished, machined, and tested components ready for export.

Frequently Asked Questions (Q&A)
Q1. What is the difference between C95400 and C95500 aluminum bronze castings?
C95400 contains no nickel and offers excellent strength and wear resistance, making it suitable for general engineering. C95500 (Nickel Aluminum Bronze) contains 3.5–5.5% nickel, which significantly improves corrosion resistance in seawater and resistance to cavitation erosion — making it the preferred choice for marine propellers, sea water pumps, and offshore equipment.
Q2. Do you offer machined aluminum bronze castings or only raw castings?
We offer both. Our in-house CNC machining facility can produce fully finished components ready for assembly. We can machine to your drawing tolerances and provide dimensional reports.
Q3. Can you manufacture aluminum bronze sand castings to ASTM standards?
Yes. We regularly produce castings conforming to ASTM B148, ASTM B505, and related standards. Our material test certificates reference the applicable ASTM designation.
Q4. What is your minimum order quantity for sand castings?
Our MOQ is as low as 5 pieces, and we welcome prototype and sample orders. Pricing is adjusted accordingly for low-volume runs.
Q5. How do you verify the chemical composition of aluminum bronze castings?
Every heat is verified using an in-house optical emission spectrometer (OES) prior to pouring. Certificates of chemical analysis are provided with each shipment.
Q6. Can you supply castings with third-party inspection (TPI)?
Yes. We regularly work with TPI agencies such as Bureau Veritas, SGS, Lloyd’s Register, TÜV, and RINA. We can arrange for TPI at the foundry before despatch.
Q7. What is your typical lead time for aluminum bronze sand castings?
For standard production runs, our lead time is 4–6 weeks from drawing approval and order confirmation. Rush orders can sometimes be accommodated in 2–3 weeks depending on complexity and workload.
Q8. Do you provide material test certificates (MTC) with shipments?
Yes. Every shipment is accompanied by a full MTC covering chemical composition, mechanical properties, heat treatment details, and NDT results as applicable.
Q9. Are your aluminum bronze castings suitable for seawater applications?
Absolutely. C95500 Nickel Aluminum Bronze is specifically engineered for long-term performance in seawater, brackish water, and marine environments. It resists dezincification, stress corrosion cracking, and biofouling.
Q10. Can you reproduce castings from a sample or physical part (reverse engineering)?
Yes. We can measure existing parts, create 3D models, develop patterns, and reproduce castings to match your original component — often with improvements to the design for better castability.
Q11. What non-destructive testing (NDT) methods do you offer?
We offer radiographic testing (RT), ultrasonic testing (UT), dye penetrant testing (DPT), magnetic particle testing (MPT), and visual inspection (VT), as per customer specifications.
Q12. Do you export aluminum bronze castings? Which countries do you supply to?
Yes. We are an established exporter supplying to the USA, UK, Germany, Australia, Canada, Singapore, UAE, Norway, Netherlands, South Africa, and many other countries. We handle all export documentation and logistics.
Q13. How is your export packaging done for aluminum bronze castings?
Castings are individually wrapped in moisture-resistant material, packed in custom wooden crates or cartons with foam/bubble wrap cushioning, and labelled with heat number, PO, and destination details. Sea-worthy and airworthy packaging options are available.
Q14. Can aluminum bronze sand castings be used in food-grade or drinking water applications?
Aluminum bronze alloys are generally not recommended for potable water applications due to potential aluminum leaching. For food-grade water contact applications, we recommend gunmetal (LG2 or 85-5-5-5) castings instead. Our technical team can advise the right alloy for your application.
Q15. What quality certifications does Brass Parts India hold?
We maintain ISO 9001 quality management systems and can supply to customer-specific quality plans. Our foundry and machining processes are regularly audited by international customers and third-party certifying bodies.
Export-Worthy Packaging
Each casting order is packed to withstand international sea freight and air freight conditions. We use custom-built wooden crates lined with moisture-barrier film, with each piece individually wrapped in VCI (Volatile Corrosion Inhibitor) poly bags. Packing lists, shipper marks, and hazardous material compliance declarations (where required) are provided as standard. Our packaging has been approved by customers in the USA, UK, Germany, and Australia as meeting their inbound goods handling requirements.
