The Al‑Brass tube offered by Bluemetal Co., Ltd is an alloy of copper, zinc and 2‑3% aluminium, identified as CuZn20Al2 and equivalent to C68700. It is supplied in seamless form and is marketed for environments that demand resistance to seawater corrosion and bio‑fouling. The supplier cites applications such as power‑plant condensers, offshore heat exchangers and marine cooling systems.
Al‑Brass combines roughly 75‑80% copper, 18‑22% zinc and 2‑3% aluminium, giving it a density of about 8.5 g cm‑3 and a typical tensile strength of 300 MPa. In the industry the alloy is standardised under designations C4430/KSD5301 and C6871‑C6872, and it conforms to ASTM B111 for seamless copper‑alloy tubing. Typical product ranges include outer diameters from 15 mm to 200 mm with wall thicknesses between 1.5 mm and 10 mm, supplied in 10 m coils wrapped in protective film.
Buyers such as energy‑sector engineers, desalination plant contractors and naval equipment manufacturers often request this tube for its durability in aggressive saline conditions. The listing does not disclose minimum order quantities, lead times or payment terms, so interested importers should confirm those details directly with Bluemetal. Trade can be arranged under standard Incoterms such as FOB Busan, with inspection options available prior to shipment.

Before placing an order, verify the supplier’s production capability and request recent batch certificates that confirm the alloy composition and ASTM B111 compliance. It is advisable to ask for a third‑party inspection report, especially if the tubes will be used in critical power‑plant or marine systems.
Logistics should be clarified early: confirm whether the shipment will be FOB Busan or CIF another port, and agree on the Incoterm that matches the buyer’s risk tolerance. Payment terms are typically negotiated on a letter‑of‑credit basis for first‑time transactions, but the exact method should be confirmed with Bluemetal before contract signing.
Quality control can include dimensional checks, wall‑thickness measurement, and non‑destructive testing for surface defects. Request a copy of the inspection certificate and, if possible, arrange for an on‑site audit or a pre‑shipment sample inspection to ensure the tubes meet the specified tolerances and corrosion‑resistance expectations.
