The product is a three‑ply composite sheet known as BMB‑3PLY, featuring brass outer layers bonded to a mild‑steel core. It is promoted for ammunition tracer applications and industrial uses that require enhanced heat tolerance and superior electrical conductivity compared with single‑material brass sheets. The supplier claims the construction delivers roughly a 10 % cost saving while retaining the corrosion resistance expected of copper alloys.
Brass outer layers are typically composed of a CuZn alloy with about 70 % copper and 30 % zinc, while the mild‑steel core provides structural strength. Industry practice for similar clad sheets uses a total thickness between 0.5 mm and 2 mm, delivering a tensile strength around 300 MPa and an electrical conductivity near 30 % IACS. These values align with standards such as ASTM B179 for copper‑clad steel, which many manufacturers follow for consistency in defence and electronics markets.
Target buyers include defence contractors, ammunition manufacturers and electronics producers that need a material combining conductivity with heat resistance. The sheet is normally supplied in standard industrial dimensions and coiled for ease of handling. The listing does not disclose minimum order quantities, pricing, lead times or Incoterms, so prospective purchasers should request these specifics directly from CS‑Tech.

When ordering, confirm the exact brass alloy composition of the outer layers and the grade of the mild‑steel core to ensure they meet your performance criteria. Request any available material test certificates, such as tensile strength or conductivity reports, and verify that the product complies with relevant standards for defence or electronic applications. Also check that the HS code used for customs aligns with the typical 7308 classification for clad metal sheets.
Logistics for this product are usually arranged via sea freight from Busan ports, but the supplier has not disclosed lead‑time, Incoterms or payment terms. Ask CS‑Tech to specify the preferred Incoterm (e.g., FOB, CIF) and any required advance payment schedule. Confirm container loading capacities and whether the coiled packaging meets your warehouse handling procedures.
Arrange an independent inspection of the clad layers before shipment, focusing on bond integrity between brass and steel and the sheet’s thickness uniformity. Common quality checks include visual inspection for surface defects, dimensional measurement, and electrical conductivity testing. Ensure the supplier can provide a final inspection report and all necessary export documentation, such as a certificate of origin and material safety data sheet, to facilitate smooth customs clearance.
