-
Heavy Construction & Structural Engineering: Used in architectural frameworks, seismic braces, and custom fasteners where high strength, corrosion resistance, and durability are critical.
-
Industrial Welding & Fabrication: Serves as premium filler rod stock, welding fixtures, and base material for welded assemblies requiring excellent thermal conductivity and joint integrity.
-
Power & Electrical Infrastructure: Ideal for high-current busbars, switchgear components, and grounding systems that demand both high conductivity and structural rigidity.
-
Machined Components & Hardware: Perfect stock for CNC machining of valves, fittings, bearings, and other parts needing a fine, isotropic grain structure for precision finishing.
-
Exceptional Purity & Consistency: With 99.9% minimum copper content and very low oxygen levels, these bars ensure predictable thermal/electrical performance and reduce the risk of porosity in critical welds or castings.
-
Superior Mechanical Workability: The fine, non-directional grain structure after heat treatment allows for excellent machinability, ductility for complex bending, and suitability for fine polishing or grinding without tearing or cracking.
-
Enhanced Durability: The alloying elements impart improved tensile strength and hardness over pure copper, while maintaining outstanding corrosion and weather resistance for long-term outdoor or industrial use.
-
Certified & Traceable Quality: Each batch is supported by Mill Test Certificates and can be third-party verified (SGS, TVE), providing full traceability and confidence for regulated projects and export compliance.
Q1: Are C2600-C2800 considered pure copper or brass?
A1: While they have very high copper content (99.9% Min), the C2600-C2800 series are technically classified as low-alloyed brasses (copper-zinc alloys). They offer a unique combination: the conductivity and corrosion resistance close to pure copper, with the added strength and workability of brass.
Q2: What is the benefit of the "non-directional grain structure" mentioned?
A2: A non-directional (isotropic) grain structure means the material's properties are uniform in all directions. This is crucial for precision machining, fine polishing, and forming operations, as it prevents uneven finishing, tearing, or unpredictable behavior during fabrication.
Q3: Can you really deliver standard specifications in 5 days?
A3: Yes, for common diameters and grades we maintain a strategic stock. Standard specification items can be prepared for shipment within 5 days of order confirmation, subject to stock availability and logistics planning.
Q4: What hardness should I choose for welding and bending applications?
A4: For welding as a base material, 1/4 Hard or 1/2 Hard is recommended for better formability and to reduce stress. For bending operations, 1/4 Hard (softer temper) is ideal for complex bends without cracking. For structural parts that will be machined but not formed, Hard (H) temper provides greater stability.
Q5: What payment methods and shipping terms do you offer?
A5: We offer flexible payment including T/T, L/C at sight, and online options. Standard trade terms are FOB, CFR, or CIF from any major port. Goods are packed in export-standard, seaworthy packaging for container, bulk, or train transport globally.
