Import Brass Ingot - Hpb57-3 — Buy in wholesale FOB from Supplier in Indonesia

HPb57-3 leaded brass ingot from Pt. Jayaditya Aswani Mandiri is a free-machining copper alloy conforming to Chinese GB/T standards, with copper held at 57.0 to 59.0 percent, lead at 1.7 to 3.0 percent, iron and tin each capped at 1.0 percent maximum, aluminium at 0.5 percent maximum, and zinc making up the balance. The elevated lead content is deliberately engineered to produce brittle chips during high-speed machining, reducing tool wear and improving surface finish on precision-turned components. Produced in Sidoarjo, East Java, this ingot targets export markets where rapid fabrication of threaded fittings, valve stems, and automotive hardware is required.

The 1.7 to 3.0 percent lead range in HPb57-3 sits at the higher end of machinability-enhancing additions, distinguishing it from low-lead alternatives such as BKI CU1 which restricts lead to 0.5 percent maximum. This makes HPb57-3 unsuitable for potable water applications in jurisdictions with strict lead limits, but ideal for industrial and automotive components where subsequent finishing seals the surface. Iron and tin residuals up to 1.0 percent contribute to matrix strength and corrosion resistance, while the aluminium limit controls oxidation during remelting. Typical ingot dimensions and as-cast grain size are not specified by the supplier and should be requested before order placement.

Buyers for this grade span precision-machining shops, automotive tier-two suppliers, and hardware manufacturers across Asia, Europe, and North America. Common end-products include connector bodies, fasteners, gears, and intricate valve components where tight dimensional tolerance and excellent machinability outweigh lead-content concerns. Trade specifics such as MOQ, standard package weights, and lead times are absent from the listing, so direct negotiation with Pt. Jayaditya Aswani Mandiri is essential. Importers should also confirm whether the supplier offers pre-shipment sample bars for tool-life testing.

Pt. Jayaditya Aswani Mandiri is based at Raya Trosobo Km. 24 No. 07, Sidoarjo, 61257, East Java, Indonesia. The company carries a harbor-tier trust designation and currently shows a 0.00 percent response rate with zero average response hours on platform channels. This profile suggests that proactive direct outreach, rather than passive enquiry, will be necessary to establish commercial contact and obtain binding quotations.

The supplier's export focus centres on brass ingots manufactured to both Indonesian BKI and Chinese GB/T standards, indicating flexibility in serving markets with different specification preferences. No information is provided about founding year, production capacity, number of employees, annual turnover, or named customers. Buyers should independently verify the company's foundry equipment, melt analysis capabilities, and whether it holds ISO 9001 or equivalent quality-management certification. A factory audit or video inspection may be warranted given the absence of detailed profile data.
