Brass c2680

C2680 brass, commonly known as 65/35 Yellow Brass, consists of approximately 64-68% Copper and the remainder Zinc. It is prized for its excellent cold workability, high ductility, and good corrosion resistance. When sourcing, you must specify the Temper (e.g., O, 1/4H, 1/2H, H, EH) as this determines the tensile strength and hardness. Ensure the material meets ASTM B36 or JIS H3100 standards to guarantee consistency in industrial applications like electronic components and automotive parts.

For B2B procurement, quality validation is critical. You should require Mill Test Certificates (MTC) that detail the chemical composition and mechanical properties. For exports to the EU, ensure the material is RoHS and REACH compliant, specifically regarding lead (Pb) content limits. Conduct hardness tests (Vickers or Rockwell) and grain size analysis to ensure the brass can withstand deep drawing or stamping processes without cracking.

C2680 is a versatile alloy used extensively in electrical engineering for terminals, connectors, and lamp caps due to its conductivity. It is also the standard choice for deep-drawn parts like radiator shells, musical instruments, and decorative hardware. Its aesthetic golden hue makes it popular for architectural trim, while its anti-corrosive properties allow for use in mild atmospheric and water-contact environments.

Brass pricing is highly sensitive to the LME (London Metal Exchange) copper and zinc spot prices. To optimize costs, consider long-term contracts to hedge against price volatility. Look for suppliers on Made-in-China.com who offer tiered pricing; typically, orders exceeding 2 tons can yield a 5-10% discount. Additionally, sourcing slitted coils rather than wide sheets can reduce your internal processing waste and labor costs.

The primary risks include material substitution (delivering lower-grade scrap brass) and weight discrepancies. To mitigate these, use Trade Assurance services and hire third-party inspectors like SGS or Intertek to verify the chemical composition and net weight before the balance payment. Always confirm the packaging method, as brass is susceptible to oxidation and water spots during sea freight; insist on vacuum packaging or moisture-proof paper with wooden pallets.

Focus negotiations on tolerance levels and lead times. Standard thickness tolerances can vary; negotiating a tight tolerance (e.g., ±0.01mm) ensures better production yield. For payment, a 30% deposit and 70% against the Bill of Lading (B/L) is standard. For established buyers, you can negotiate Net 30 terms after the third successful transaction. Always verify the supplier's Export License and their history on Made-in-China.com to ensure they are a legitimate manufacturer rather than a small trading house.

Brass is high-density and heavy, so Sea Freight (FCL or LCL) is the only economically feasible method for bulk orders. Ensure the supplier uses reinforced 20GP containers to prevent floor damage. For shipping to specific regions, clarify the Incoterms (FOB or CIF); FOB is generally preferred for buyers who have their own freight forwarders to better control demurrage and detention costs at the destination port.
