What is Brass Sand Casting?
Brass sand casting is the process of pouring molten brass alloy into a mould made from specially prepared sand (silica, olivine, or chromite sand bound with clay or chemical binders). Once cooled and solidified, the sand mould is broken away to reveal the casting. Sand casting is the most versatile and widely used metal casting process, suitable for a vast range of brass alloys, part geometries, and production volumes — from a single prototype to high-volume production runs of thousands of pieces per month.
Brass sand castings offer excellent value, design flexibility, and the ability to incorporate complex cores for internal cavities — making them ideal for valve bodies, pump casings, plumbing fittings, electrical housings, and architectural hardware.

Key Applications
Brass sand castings from Brass Parts India serve a wide spectrum of industries and applications. In plumbing and water supply, brass castings form the bodies of gate valves, ball valves, angle valves, stop cocks, and water meters. The electrical industry uses brass sand castings for switchgear housings, bus bar connectors, and earthing components. Marine applications include sand-cast brass seacocks, deck fittings, and navigation instrument housings. In the automotive sector, carburettor bodies, hydraulic valve blocks, and fuel system components are commonly cast in brass. Architectural and decorative uses include door handles, locks, stair railings, and ornamental castings where the warm golden colour and corrosion resistance of brass are valued aesthetically.

Our Technical Expertise
Brass Parts India has specialised in brass and copper-alloy casting since inception. Our foundry team includes experienced metallurgists, pattern makers, and casting engineers who understand the nuances of brass alloy behaviour — including melt treatment for low gas porosity, correct pouring temperatures, and riser design for sound castings. Our OES spectrometer verifies every heat before pouring, and our CMM and optical gauges ensure dimensional conformance on every batch. We are fully capable of producing castings to ASTM, BS, DIN, JIS, and IS standards and providing the corresponding traceability documentation.

What Separates Us from Other Manufacturers
We are not just a casting supplier — we are a total solution provider. Many customers come to us for castings and stay because of our ability to handle everything from alloy selection advice and DFM review to machining, testing, export documentation, and third-party inspection coordination. Our in-house capabilities eliminate the need for you to manage multiple vendors, simplifying your supply chain and reducing risk.
Our Flexibility to Customise Parts
Whether you need castings with special alloy compositions, specific thread forms, machined bores and faces, custom surface treatments (such as chrome plating, nickel plating, or lacquering), or non-standard sizes outside published catalogues, we can accommodate your requirements efficiently and cost-effectively. We also offer reverse-engineering services for obsolete or legacy brass castings where original drawings are no longer available.

Frequently Asked Questions (Q&A)
Q1. What brass alloys are most commonly used for sand casting?
The most popular brass casting alloys are C83600 (85-5-5-5 gunmetal), C84400 (semi-red brass), C85700 (yellow brass), and C86300 (manganese bronze). The choice depends on required strength, corrosion resistance, machinability, and application.
Q2. Is brass sand casting suitable for pressure-bearing parts such as valve bodies?
Yes. With the correct alloy selection (typically semi-red or red brass), proper mould design, and hydrostatic pressure testing, brass sand castings are entirely suitable and widely used for valve bodies and pressure fittings rated up to PN25 and beyond.
Q3. How do I choose between yellow brass and red brass for my casting?
Red/semi-red brass (higher copper, lower zinc) offers better corrosion resistance and pressure tightness — ideal for plumbing valves and marine fittings. Yellow brass (lower copper, higher zinc) offers higher strength at lower cost — suitable for general purpose and decorative castings.
Q4. Can you produce lead-free brass castings for drinking water applications?
Yes. We offer silicon brass (C87600), eco-brass, and other low-lead or lead-free alloys for potable water contact applications, meeting NSF/ANSI 61, WRAS, and CA AB1953 (Prop 65) lead-free requirements.
Q5. What is your capacity for brass sand castings per month?
Our monthly casting capacity is several hundred tonnes per month of non-ferrous castings. We can scale production up or down based on customer requirements and maintain a buffer stock programme for high-volume customers.
Q6. What NDT tests are available for brass castings?
We offer radiographic testing (RT), dye penetrant testing (DPT), pressure testing (hydrostatic and pneumatic), dimensional inspection, and spectrometric chemistry verification.
Q7. Do you supply brass castings with complete machining?
Yes. We offer a full range of CNC turning, milling, drilling, boring, and tapping services. Castings can be delivered in machined-only, semi-machined, or as-cast condition as required.
Q8. What documentation is provided with brass sand casting shipments?
Standard documentation includes Material Test Certificate (MTC), packing list, commercial invoice, and Declaration of Conformity. Additional documents such as inspection reports, NDT certificates, and third-party certificates are available on request.
Q9. Can you cast complex shapes with internal cores in brass?
Yes. We regularly produce complex brass castings with internal passages, blind holes, undercuts, and other geometric features using sand cores. Our experienced core-making team can produce cores in a variety of sand binders including CO₂-cured, cold box, and oil-sand.
Q10. What is your minimum order for brass sand castings?
We accept orders as small as a single prototype piece. For production orders, we work with customers to determine the most cost-effective batch size based on pattern tooling amortisation and production scheduling.
Q11. How do you ensure consistent alloy quality in brass castings?
Every heat of brass is analysed using our in-house OES spectrometer before pouring. We maintain a strict incoming quality control procedure for all raw materials (copper, zinc, tin, lead, etc.) and use only verified, traceable ingot material.
Q12. Can you cast to imperial or metric dimensions?
Yes. We work in both metric and imperial measurement systems and can produce castings conforming to any internationally used drawing standard.
Q13. Do you offer surface finishing for brass castings?
Yes. We offer shot blasting, grinding, barrel tumbling, electroplating (nickel, chrome, zinc), and painting as additional finishing operations. These can be arranged through our trusted partners or performed in-house depending on the process.
Q14. What is the average lead time for brass sand castings?
For repeat orders with existing patterns, 2–4 weeks. For new components including pattern making, 5–8 weeks for first articles. We offer expedited services for urgent requirements.
Q15. Do you have experience with custom architectural brass castings?
Yes. We have produced architectural brass castings including door hardware, handrail brackets, decorative column caps, stair balusters, and signage components for projects in the UK, UAE, and Australia. Our finishing capabilities allow delivery in polished, lacquered, or patinated conditions.
