A request for AB2 is incomplete until the grade, governing standard, supply form, test certificate and finished dimensions are fixed. By the end, you can identify the right material for a property component, compare aluminium bronze AB2 price in Mumbai on an equal basis, and send a supplier an enquiry that produces usable quotations.
Key takeaways
- Confirm whether AB2 means CuAl10Fe5Ni5, EN CC333G or BS 1400 AB2.
- Match castings, plates, bars or profiles to the component drawing.
- Compare prices with testing, machining, delivery and minimum-order costs included.
- Request heat numbers, chemical analysis, mechanical tests and dimensional inspection records.
What AB2 means and what the material certificate must prove
“AB2” is not a universal international grade name. It commonly identifies a cast aluminium bronze close to CuAl10Fe5Ni5, but you must confirm the designation against the purchasing standard, such as EN CC333G, BS 1400 AB2 or the supplier’s stated equivalent.
A certificate that only says “aluminium bronze” does not verify the alloy. Ask for a heat or melt number linking the certificate to your supplied material, plus actual test results for:
- Aluminium: approximately 9–11%
- Iron: approximately 3–6%
- Nickel: approximately 3–6%
- Manganese: the actual reported value and permitted range
- Copper: balance
- Tensile strength, yield strength and elongation
- Brinell or other specified hardness
- Density, if weight or section calculations depend on it
Compare those results with the exact standard and grade written on your purchase order. Nickel and iron are not minor details: they influence strength, wear resistance and corrosion behaviour. A generic copper-alloy certificate cannot establish compliance.
Also check the product form and manufacturing route. Casting method, heat treatment, section size and microstructure can change the mechanical results, so a certificate for cast bar does not automatically qualify a valve casting or machined bush.
Before you buy aluminium bronze AB2 in Mumbai, require the drawing revision, supplied dimensions, inspection level and certificate type in the quotation. Reject any offer that gives a nominal grade without traceable heat identification and actual chemistry.
Which AB2 form suits a property-project component
Choose the nearest finished form, not the most familiar stock shape: buy a machined part for a critical, drawing-controlled component, a bush for a bearing location, and a casting when the geometry cannot be cut economically from stock.
| Option | Best fit | Main caution |
|---|---|---|
| Cast bar | Pins, small shafts, simple rings and turned parts | Confirm diameter, casting condition and machining allowance |
| Plate | Wear plates, guide plates and flat valve parts | Check thickness tolerance, porosity and flatness after machining |
| Block | Valve bodies, heavy guides and large one-off components | You pay for material removed during machining |
| Bush | Pump, valve and door-hardware bearing locations | Specify bore, outside diameter, length, clearance and lubrication |
| Valve component | Seats, discs, stems or bodies supplied to a valve drawing | Require pressure-duty dimensions and a defined inspection level |
| Casting | Complex pump, valve or bespoke property-project geometry | Pattern cost and shrinkage allowance affect small orders |
| Machined part | Repeatable installation-ready components | Include tool wear, low cutting speeds, coolant and chip removal in the quote |
Do not order “AB2 sheet”, “AB2 extrusion” or “AB2 profile” without checking the designation. AB2 is a cast aluminium-bronze grade, not 6063-T5 aluminium used for common window frames, doors and architectural profiles.
For aluminium bronze for commercial projects, separate appearance and architectural detailing from wet-service or high-load duties. Send the finished drawing, revision, quantity, tolerances and surface finish; the supplier can then recommend a cast blank or deliver the machined component. A cheap blank can become the expensive choice once machining time and scrap are added.
When AB2 is better than aluminium, brass or stainless steel
Choose AB2 for a component that must carry high contact loads, resist sliding wear and remain reliable in wet, chloride-bearing service. That makes aluminium bronze for commercial projects a sensible choice for valve parts, pump components, bushes, guides, wear plates and exposed hardware—not automatically for every architectural fitting.
| Option | Best fit | Specify another material when |
|---|---|---|
| AB2 | High-load bushes, valve seats, pump parts, marine or chloride exposure, abrasive contact | Low weight, bright architectural appearance or standard extruded sections matter more |
| Architectural aluminium, such as 6063-T5 | Window frames, doors, partitions, profiles and lightweight cladding | The part faces concentrated loads, severe abrasion or sustained bearing pressure |
| Brass | Decorative fittings, moderate-duty hardware and easy machining | Chlorides, ammonia, high loads or wear could cause premature damage |
| Stainless steel | Hygiene-critical areas, strong oxidising exposure, thin fabricated sections and a clean finish | Sliding wear, galling risk or bronze-compatible bearing behaviour is the priority |
Specify AB2 only after checking the actual duty: load, movement, temperature, water chemistry, chloride concentration, abrasion and maintenance access. A heavier alloy also affects hinges, anchors and installation handling.
For visible architectural work, assess colour, patina, fire requirements, slip resistance and cleaning before choosing cast AB2. Check fastener compatibility to avoid galvanic corrosion. If the design needs a lightweight extruded profile, conventional architectural aluminium or a wrought aluminium-bronze grade is more appropriate; AB2 is an engineering casting alloy, not a substitute for 6063-T5.
How to compare aluminium bronze AB2 price in Mumbai
A quoted aluminium bronze AB2 price in Mumbai is comparable only when every supplier prices the same finished item, supply condition and acceptance level. Compare the mass of the completed component, not price per metre or per piece: aluminium bronze weighs roughly 7.5–7.8 g/cm³, compared with about 2.7 g/cm³ for architectural aluminium.
Send every bidder the same enquiry details:
- Drawing number and revision, finished dimensions, tolerances and surface-finish grade
- Required delivery form: casting, cast bar, plate, block, bush, or machined component
- Machining allowance, final weight and quantity by heat or batch
- Casting method or supply condition, such as sand cast, centrifugal cast, continuous-cast or forged
- Operating temperature, fluid or atmosphere, and hardness or strength requirement
- Inspection level, chemical analysis, mechanical tests and certificate requirements
- Packing, delivery location, required date and whether partial deliveries are acceptable
Require quotations to separate these cost lines:
| Cost line | What to compare |
|---|---|
| Metal | Net finished weight, input weight and alloy yield |
| Conversion | Casting, bar production or forging charge |
| Tooling | Pattern, core box or dedicated fixture cost |
| Machining | Operations, tooling wear, coolant and chip removal |
| Testing | Chemical, tensile, hardness, dimensional and non-destructive tests |
| Logistics | Packing, freight, taxes and unloading |
| Scrap | Returnable scrap credit or supplier’s yield assumption |
A small one-off casting can be dominated by pattern cost; repeat quantities can reduce its unit impact. The cheapest blank can still produce the highest total cost when AB2 machining takes longer and wears tools faster.
The Mumbai purchase checklist for drawings, testing and delivery
Send the supplier a controlled drawing, not just “AB2 for a property project.” If you plan to buy aluminium bronze AB2 in Mumbai, give the aluminium bronze AB2 supplier in Mumbai enough data to price the same finished part, test it against the same criteria and deliver it in the required form.
1. Attach the latest drawing revision, with finished dimensions, tolerances, machining allowance, hole details, surface-finish requirement and quantity. State whether you need cast bar, plate, block, bush, valve component, casting or machined part.
2. Write the material specification by standard, not trade name alone. State the governing specification, supply condition and required limits for aluminium, iron, nickel, manganese and copper. Do not assume C95500 is identical to every product called AB2.
3. Describe service conditions: operating-temperature range, fluid or atmosphere, immersion or splash exposure, load, wear duty and contact with fasteners. Add the required tensile strength, yield strength, elongation, hardness and density where the design depends on them.
4. Define acceptance tests and documents before ordering. Request the chemical-analysis report, tensile or hardness results, dimensional inspection report, heat or batch number, traceability and non-conformance procedure. Specify inspection level, sampling plan and whether an independent inspection agency is required.
5. State the delivery form, packing method, destination, required delivery date and partial-delivery rules. Ask the quotation to separate metal weight, conversion or casting, pattern or tooling, machining, heat treatment, inspection, packing, freight, taxes and scrap assumptions.
Aluminium World can assess the request more accurately when the drawing revision and finished form accompany the enquiry; those details also expose whether a one-off pattern cost outweighs a repeat-order tooling investment.
