1. Strategic Importance of the Dedicated Red Copper Bar & Busbar Warehouse
Within CYMBER’s nationwide network of specialized warehousing facilities, the Red Copper Bar & Busbar Core Warehouse located in Zhejiang Province stands as the most focused and mission-critical facility in our entire system. This warehouse handles only one product category—red copper round bars, copper busbars, large-diameter straight copper tubes, and copper squares—but achieves the industry’s deepest and most complete size coverage within this single category. For high-end manufacturing enterprises in power transmission, new energy, rail transit, precision tooling, and marine engineering, the availability of full-size red copper bars and busbars directly impacts procurement efficiency, working capital occupancy, and production continuity. By establishing this independent “Core Warehouse”, CYMBER ensures that the most supply-sensitive copper product line is under complete control, guaranteeing major clients immediate access to any required specification at any time.
2. Key Advantages of the Core Warehouse
- Category Focus with Unmatched Size Completeness
- Permanent stock exceeding 1,000 tons
- Full diameter range from Φ6mm to Φ450mm for round bars
- Thickness from 5mm to 300mm for busbars
- Complete coverage of large straight copper tubes and copper squares (standard and non-standard)
- Essentially: “If a size exists in the industry, we stock it.”
- 5,000 m² Dedicated Storage Facility
- Heavy-duty cantilever racking combined with ground-level storage, capable of holding single bars up to 8 tons
- Clearly zoned layout: round bar zone, busbar zone, straight tube zone, square zone, inspection zone, and dispatch zone for precise location and rapid picking
- 24-Hour Ready-to-Ship Capability
- Backed by both the Zhejiang Core Warehouse and the Zhejiang Comprehensive Copper Stock Center
- 99.9% of standard specifications available for same-day dispatch with next-day delivery across Jiangsu, Zhejiang, Shanghai, Anhui, and Shandong
- Rare out-of-stock items can be requested via internal OA system with direct factory replenishment within 72 hours—lead time among the fastest in the industry
- Supported by Five Specialized + Two Comprehensive Warehouses Nationwide CYMBER operates:
- Aluminum Sheet Dedicated Warehouse
- Aluminum Extrusion Dedicated Warehouse
- Copper Plate & Strip Dedicated Warehouse
- Red Copper Tube Dedicated Warehouse
- Red Copper Bar & Busbar Core Warehouse (Zhejiang) Plus large comprehensive copper/aluminum warehouses in Zhejiang and Jiangsu, and a full-range aluminum extrusion hub. This “one warehouse, one category” philosophy pushes inventory depth for each copper and aluminum product line to industry-leading levels.
3. Built for Enterprises That Cannot Afford Supply Interruptions
We fully understand that for clients with annual copper consumption in the hundreds of tons, the greatest risk is not price fluctuation but the sudden unavailability of a critical size that halts production lines. The CYMBER Red Copper Bar & Busbar Core Warehouse exists to minimize that risk to the lowest possible level: 1,000+ tons of permanent stock, 5,000 m² of dedicated space, the industry’s most complete size matrix, and true 24-hour dispatch capability. These are not marketing claims—they are verifiable realities open to on-site audit at any time.
4. Converting
Matte is transferred via electrically heated launders or ladles to Peirce-Smith converters or continuous converting furnaces.
4.1 Slag-Forming Stage
Oxygen-enriched air (25-35% O₂) is blown to oxidize iron sulfide. Slag containing 2-8% Cu is skimmed and returned to flash smelting.
4.2 Copper-Making Stage
Continued blowing oxidizes Cu₂S to blister copper (98.5-99.3% Cu) at 1180-1230°C.
