We buy scrap ship propellers in Singapore — manganese bronze, nickel-aluminium bronze, brass, and stainless steel propellers of any size and condition. From small outboard props under 5 kg to main-engine propellers at 5+ tonnes. Shipyard and marine-contractor pickup direct from Tuas, Jurong, Pasir Panjang, and Keppel. Same-day payment on verified alloy.

How to Sell Your Scrap Propeller in Singapore

1. Photograph the propeller — full view, close-up of hub, and any stamped markings or cast-in codes. WhatsApp to +65 9106 7577.
2. We quote on photos — alloy is usually identifiable from colour, hub design, stamped grade, and vessel class.
3. We confirm with an alloy spectrometer on site at pickup or at our yard — the reading determines the final rate.
4. Lifting and removal — we bring crane and rigging for props over 50 kg. For main-engine props off a vessel, we coordinate with the shipyard.
5. Weigh and settle same-day against the alloy-verified rate.

Where Scrap Propellers Come From

• Shipyard repair work — props replaced during drydocking due to cavitation damage, blade cracks, or efficiency upgrades.
• Vessel scrapping — full decommission of tugs, barges, workboats, and older merchant vessels.
• Naval and coast guard retirement — stainless and NAB props from decommissioned patrol and auxiliary craft.
• Yacht and pleasure craft — prop upgrades or replacement after grounding damage.
• Outboard engine replacement — aluminium and brass small-craft props, typically in bulk lots from marine dealers.

Identifying Propeller Alloy

Alloy determines the rate band more than any other factor, so it pays to identify correctly before calling. Key signals:

• Manganese bronze is yellow-gold with a slight greenish oxidation. Most common alloy on merchant marine props. Often stamped with a grade code near the hub.
• Nickel-aluminium bronze (NAB) is darker — olive to bronze-brown — denser feel than manganese bronze. Common on naval, high-power, or high-torque installations.
• Aluminium bronze is golden-brown, lighter than NAB. Used on yachts, workboats.
• Stainless steel is obvious — silver-grey, magnetic response varies (304 slight, 316/317 nil). Heavy for its size.
• Aluminium is unmistakable — light weight, dull silver, typically small diameter (outboard).

We run a handheld X-ray fluorescence (XRF) spectrometer on every non-trivial propeller before settlement, so there is no guesswork at payment time. You see the reading; the rate follows the alloy.

Shipyard and Marine-Contractor Pickup

We service the Tuas, Jurong, and Pasir Panjang marine clusters directly with our own low-loader and crane truck. Pickup is free for propellers over 50 kg; smaller props can be dropped at our 170 Gul Circle yard during business hours. For multi-prop lots from vessel-scrapping jobs we can schedule a same-week collection window and settle against one ticket. We also handle related marine scrap — shafts, stern tubes, rudder stocks, bronze through-hulls, sea-chests, and scuppers.

Frequently Asked Questions

Can I sell a single damaged propeller in Singapore?

Yes — even a single damaged or cavitation-pitted prop has full scrap value. The alloy and weight determine the price; cosmetic condition doesn’t matter because everything melts down.

How much is a scrap bronze propeller worth?

It depends on the alloy. Manganese bronze pays around $4.50–$5.20/kg; nickel-aluminium bronze pays $5.50–$6.80/kg. A typical 150 kg manganese bronze propeller is worth $675–$780 at current rates. Call for a firm quote.

Do you pick up propellers from shipyards?

Yes — we run regular collections from Tuas, Jurong, and Pasir Panjang shipyard clusters. Free pickup for props over 50 kg; crane and rigging provided on site.

How do you verify propeller alloy?

We use a handheld X-ray fluorescence (XRF) spectrometer at the point of settlement. The reading is shown to the seller, and the rate follows the verified alloy — no guesswork, no disputes.

Do you buy main-engine propellers from vessel scrapping?

Yes — we handle main-engine props of any size, up to 5+ tonnes. For ships under deconstruction we can coordinate with the yard on removal scheduling and issue a single weighing ticket covering the prop lot plus any related shafting or stern tube non-ferrous.

Is Molten Steel licensed to buy marine scrap in Singapore?

Yes — we are a fully NEA-licensed scrap metal dealer, which covers marine scrap acquisition. See our licensing page for the exact licences on file.
