As a trusted manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory is proud to present our high-quality Copper Water Bar for Laser Welding Head Cooling (10mm OD, 6mm ID, 500mm Length, Nickel Plated). This precision cooling component is engineered to efficiently dissipate heat from laser welding heads, ensuring stable operation and extended equipment lifespan. With over two decades of manufacturing experience and annual export values reaching US$5–10 million, we deliver reliable solutions trusted by clients across North America, Europe, Asia, and beyond.
Our copper water bar is crafted from high-purity copper (C1100) with a nickel-plated surface, offering excellent thermal conductivity and corrosion resistance. The precisely machined 10mm outer diameter (OD) and 6mm inner diameter (ID) provide optimal coolant flow for effective heat transfer, while the 500mm length accommodates various laser welding head configurations. Below we detail the key features, technical specifications, and benefits that make this product an essential component for your cooling system.
Key Features & Technical Specifications
- High-Purity Copper Core: 99.9% pure copper ensures maximum thermal conductivity (≈400 W/m·K) for rapid heat dissipation, protecting sensitive laser diodess from overheating.
- Nickel Plating: A uniform nickel layer provides excellent corrosion resistance, prevents oxidation, and enhances durability in water-cooling environments. The plating also withstands high temperatures and chemical exposure.
- Precision Dimensions: 10mm OD / 6mm ID with tight tolerance (±0.1mm) ensures a secure fit with standard fittings and hoses. The 500mm length offers flexibility for integration into various laser head designs.
- Smooth Inner Surface: The polished inner bore minimizes flow resistance, reducing pressure drop and improving overall cooling efficiency.
- Straightness & Consistency: Each bar is straightened to ensure linearity, critical for uniform cooling along the entire length.
- RoHS Compliant: Manufactured with environmentally friendly processes, meeting international standards (certification available upon request).

Compared to standard copper tubes, our nickel-plated water bar offers superior longevity in cooling loops. The combination of pure copper core and protective nickel coating reduces maintenance frequency and ensures consistent performance over years of operation. The 10mm OD / 6mm ID dimension is widely adopted in laser welding systems, making it a drop-in replacement for many OEM designs.
Benefits for Your Laser Welding System
- Enhanced Cooling Efficiency: The high thermal conductivity of copper rapidly removes heat from the welding head, preventing thermal drift and maintaining beam quality.
- Reduced Downtime: Reliable cooling protects sensitive components, lowering the risk of overheating and extending the life of your laser diode stack.
- Easy Installation: Standardized dimensions allow direct connection to common water fittings (e.g., 6mm push-fit connectors). No special adapters required.
- Cost-Effective Solution: Our factory-direct pricing eliminates middlemen, offering you competitive rates without compromising quality.
- Versatile Compatibility: Suitable for most laser welding heads from brands like IPG, Coherent, Raycus, Datalogic, and more. Custom lengths available for non-standard systems.
Our manufacturing facility in Hengshui, Hebei, China, is equipped with advanced CNC machines and precision testing equipment. Each copper water bar undergoes strict quality control: dimensional inspection, plating thickness measurement (minimum 8μm), and pressure testing up to 10 bar. We follow ISO 9001 management principles (certification details available upon request).
With an annual export value of US$5–10 million, we have shipped millions of components to over 20 countries including the United States, Germany, Italy, Japan, Brazil, and Australia. Our ports of shipment (Tianjin, Qingdao, Shanghai, Foshan) ensure fast logistics. We offer flexible packaging: individually wrapped in foam, then bundled in cartons or wooden pallets for sea freight.

Frequently Asked Questions
Q1: What is the material purity of the copper used?
A: We use 99.9% pure C1100 copper, which offers the highest thermal conductivity among common copper alloys. This ensures efficient heat transfer for your laser head.
Q2: Is the nickel plating suitable for deionized water cooling systems?
A: Yes, the nickel plating is fully compatible with deionized water, glycol mixtures, and typical coolants. It provides excellent corrosion resistance even in aggressive environments.
Q3: Can you provide custom lengths other than 500mm?
A: Absolutely. We can manufacture any length from 100mm to 2000mm with the same quality. Please specify your requirement during ordering.
Q4: What is the typical lead time for this product?
A: For standard 500mm bars, we can ship within 7–10 days after order confirmation. Custom lengths may require 15–20 days depending on quantity.
Q5: Do you offer samples for testing?
A: Yes, we provide samples (shipping cost applies). Once you confirm the design, sample cost can be deducted from bulk order payment.
Q6: What is the maximum operating pressure for this water bar?
A: Our copper water bar is tested up to 10 bar (145 psi) with no leakage. The safe working pressure is typically 6 bar. For higher pressure requirements, please consult our engineering team.
Q7: How do you ensure the straightness of the bar?
A: After cutting and machining, each bar is straightened using a roller straightener, and then checked with a straightness gauge. Deviation is less than 0.5mm per 500mm length.
Q8: Can I get a certificate of compliance or material test report?
A: Yes, we can provide a mill certificate for copper material and a plating thickness report upon request. These documents are available for each batch.
