Ultra-Precision Thickness Control:Thickness tolerance as tight as 0.001mm / 0.002mm. Consistent gauge across the entire coil width ensures stable processing.
Exceptional Electrical Conductivity:C11000 Soft Annealed foil offers Greater than or equal to 98% IACS conductivity, minimizing power loss in busbars and battery tabs.
Advanced Anti-Tarnish Treatment:Surface passivation and anti-oxidation coating prevent surface oxidation during long-term storage and sea freight.
Superior Surface Quality (PCB Grade):Options for Double Matte (DSM) or Reverse Treated (RTF) surfaces with controlled roughness (Ra), perfect for CCL lamination.
High Tensile Strength & Ductility (Battery Grade):Specially processed battery foil with 180-200 MPa Tensile Strengh and high elongation reduces breakage during high-speed coating.
Precision Slitting & Burr-Free Edges:Clean, burr-free edges from precision slitting machines protect cutting tools and prevent short circuits in windings.
Wide Alloy Selection for Every Need:From C11000 (Red Copper), C10200 (OFC), C26000 (Brass), C51900 (Phosphor Bronze) to C7521 (Nickel Silver).
Flexible Customization (Slitting & Coiling):Custom width from 4mm to 600mm, variable coil ID (75/150/200/300mm), and traverse winding available.
Full Certification & Traceability:Supplied with EN 10204 3.1 MTC, SGS report, and PMI composition analysis. Batch numbers are traceable.
Eco-Friendly & RoHS Compliant:All materials comply with RoHS & REACH standards, free from prohibited heavy metals. Safe for electronics and automotive applications.

Product Q&A
Q:How do you guarantee the steel quality?
A:
Quality is our top priority. Every batch of steel comes with a Mill Test Certificate (MTC) showing the chemical composition and mechanical properties, strictly complying with ASTM, EN, JIS, and GB standards. We also support third-party inspections (like SGS, BV) before shipment to ensure zero defects.
Q:What is your MOQ (Minimum Order Quantity)?
A:
Generally, our MOQ is 1 Ton for regular sizes (e.g., Round Bars, Plates). For special sizes or custom cutting requirements, the MOQ may vary. Please contact us with your specific dimensions, and we will try our best to meet your needs even for trial orders.
Q:Can you supply specific grades like AISI S1, EN45A, or Inconel 625?
A:
Yes. We specialize in Specialty & Alloy Steels. We have rich experience supplying hard-to-find grades such as AISI S1 (Shock Resisting), EN45A (Spring Steel), 4140/42CrMo, and Nickel Alloys (Inconel, Hastelloy). Please share your required standard and grade, and we will check our stock or production schedule.
Q:What about the delivery time and shipping?
A:
For stock materials, we can ship within 7-10 days after receiving payment. For production orders, it usually takes 20-30 days. We offer flexible trade terms including FOB, CIF, and DAP (delivery to your warehouse). We mainly ship from Qingdao, Tianjin, and Shanghai ports.
Q:Do you provide processing services (cutting/slitting)?
A:
Yes. To save your cost and labor, we provide value-added processing services such as cutting-to-length, slitting, and simple heat treatment (annealing/quenching). We can deliver the steel ready for use in your workshop.
