Import Brass Rod - C3604 — Buy in wholesale FOB from Supplier in Indonesia

Brass Rod C3604 from Pt. Jayaditya Aswani Mandiri is a leaded free-cutting brass conforming to JIS H 3250 standards, with specified copper content of 57.0-61.0% and lead at 1.0-2.5% to optimise machinability in high-speed automatic lathe operations. The residual composition comprises zinc as balance, with nickel limited to 0.2% maximum and arsenic to 0.02% maximum, ensuring consistent cutting performance and acceptable corrosion resistance for general engineering applications. The supplier, based in Sidoarjo, East Java, indicates that size details are available on request, requiring direct enquiry to establish diameter range, length options, and current availability from their Indonesian operations.

JIS C3604 corresponds closely to ASTM C36000 and EN CW603N in international classification systems, though exact cross-references should be verified by material certification. The lead content in C3604 is deliberately controlled to form brittle chips during machining, reducing tool wear and improving surface finish compared to unleaded grades. Typical mechanical properties for this alloy in the as-extruded condition include tensile strength of 340-440 MPa and elongation of 10-25%, varying with diameter and temper. Industry-standard forms include round, hexagonal, and square profiles, with typical diameter ranges from 2mm to 50mm for precision applications, though Pt. Jayaditya Aswani Mandiri's specific inventory should be confirmed directly.

This grade serves manufacturers of precision turned parts including electrical connectors, valve stems, faucet components, fasteners, and automotive fittings where rapid production rates and tight dimensional tolerances are required. The alloy's ductility permits moderate cold forming operations, though its primary advantage remains exceptional machinability rating. Buyers in hardware, automotive, electrical, and plumbing sectors commonly specify C3604 for components where subsequent plating or finishing is anticipated, as the alloy accepts chrome, nickel, and tin coatings readily. Sourcing from Pt. Jayaditya Aswani Mandiri offers potential logistical advantages for regional Southeast Asian manufacturers, though Incoterms, minimum quantities, and lead times must be established through direct communication with the supplier.

Pt. Jayaditya Aswani Mandiri operates from Raya Trosobo Km. 24 No. 07, Sidoarjo, 61257, East Java, Indonesia, positioning the company within the Surabaya metropolitan industrial corridor, a significant manufacturing and logistics hub for Indonesian export-oriented production. The supplier holds a 'harbor' trust tier classification on the platform. The response rate is recorded at 0.00% with zero average response hours, indicating no verified communication activity through platform channels. No information is provided regarding year of establishment, facility size, production capacity, employee count, revenue, quality certifications, or specific manufacturing equipment.

The company profile does not indicate whether Pt. Jayaditya Aswani Mandiri operates as a manufacturer, distributor, or trading company, nor does it specify whether the C3604 brass rod is produced at the Sidoarjo address or sourced from domestic or international mill partners. No ISO 9001, ISO 14001, or industry-specific certifications such as IATF 16949 are mentioned. Buyers should independently verify business registration with Indonesian authorities, inspect manufacturing or warehousing facilities where possible, and request references from existing customers before advancing beyond initial enquiry. The absence of verified response metrics suggests proactive follow-up through multiple contact methods may be necessary to establish reliable communication.
