Cored Solder Wire
Cored solder wire from Buck Copper Group Limited Company is a flux-cored alloy designed for reliable solder joints in electronics manufacturing. The wire uses a Sn96.5Ag3.0Cu0.5 composition, a lead-free formulation standard for RoHS-compliant applications, and is supplied in diameters from 0.5 mm to 5.0 mm to match PCB trace widths or custom requirements. Ports of shipment include Qingdao, Shanghai, Tianjin, and Shenzhen, with standard export packaging or buyer-specified options.
The alloy’s silver and copper content improves mechanical strength and thermal fatigue resistance compared to traditional tin-lead solder, while the flux core - commonly rosin-based - reduces oxidation during hand or automated soldering. Typical industry use includes through-hole and surface-mount component assembly, where low ion contamination and residue minimisation are critical for long-term circuit stability. This composition is also standard for automotive and aerospace electronics, where vibration resistance and high-reliability joints are required.
Industrial buyers source this wire for high-volume electronics production lines, repair stations, and prototyping labs. The supplier’s ISO-certified process aligns with common quality controls for solder materials, including wettability tests and solder ball formation checks. Importers should confirm flux type (rosin, no-clean, or water-soluble) and diameter tolerances, as these affect compatibility with existing soldering equipment and reflow profiles.
| Alloy Composition | Sn96.5Ag3.0Cu0.5 |
| Diameter Range | 0.5 mm to 5.0 mm (or as required) |
| Flux Core Type | Rosin (typical for hand soldering) |
| Typical Melting Range | 217°C to 220°C (standard for SAC305 alloy) |
| Tensile Strength | typical 50 MPa to 70 MPa (varies by diameter) |
| Wettability | standard spread test > 90% coverage on copper substrate |
| Ion Contamination | low (typical < 10 µg/cm² NaCl equivalent) |
| Packaging | Standard export packaging or as required |
| Ports of Shipment | Qingdao, Shanghai, Tianjin, Shenzhen |
| Certification | ISO (as stated by supplier) |
| Solder Ball Formation | standard < 5% by volume in reflow tests |
Buck Copper Group Limited Company operates from the Qingdao West Coast Economic Industrial Zone, a logistics hub for metals and electronics materials in eastern China. The supplier’s harbor-tier trust level reflects verified export activity, though its listed response rate is currently 0%, indicating buyers should confirm availability and lead times directly. Payment methods accepted include T/T, Western Union, and L/C, with terms negotiable per order volume.
The company specialises in solder alloys and flux-cored wires, positioning itself as a materials provider for PCB assembly and industrial soldering applications. Its product line aligns with RoHS and ISO standards, but buyers should verify specific compliance documents for regulated markets. No additional details on production capacity, facility size, or client base are provided, so due diligence on these points is recommended before placing large orders.

Sourcing Cored Solder Wire from Buck Copper Group Limited Company - China Import Guide
Before ordering, verify the flux core type (rosin, no-clean, or water-soluble) to ensure compatibility with your soldering process and cleaning requirements. Confirm whether the wire meets specific industry standards, such as IPC-TM-650 for wettability or J-STD-006 for alloy composition, as these are critical for consistent performance in production environments. Request a certificate of conformance (CoC) for the batch to validate the Sn96.5Ag3.0Cu0.5 composition.
Logistics details to confirm include the port of shipment (Qingdao, Shanghai, Tianjin, or Shenzhen) and whether the supplier can accommodate FOB, CIF, or other Incoterms. Lead times may vary based on diameter and volume, so negotiate these upfront, especially for custom sizes outside the 0.5 mm to 5.0 mm range. Payment terms (T/T, L/C, or Western Union) should be agreed upon in writing to avoid delays in shipment.
Conduct quality checks on arrival by performing visual inspections for diameter consistency and flux core uniformity. For critical applications, run a sample through your soldering equipment to test wettability and residue levels. Ensure the packaging is intact and labelled correctly, and retain the CoC and any test reports for traceability. If the wire is intended for regulated industries, request additional documentation, such as RoHS compliance test results.
