Having Doubts? Our FAQ

Check all our Frequently Asked Questions

What purity levels do your copper lugs maintain?

Our standard lugs use 99.9% electrolytic copper (C10100), while premium grades reach 99.99% purity. Oxygen-free variants contain <5ppm impurities for critical applications. Each shipment includes material certification with spectrographic analysis.

What plating thickness options do you offer?

Standard tin plating comes in 3-5μm, while heavy-duty marine plating reaches 8-12μm. Gold plating (50μ") is available for aerospace applications. We can customize any plating thickness with ±0.5μm options.

What tolerance levels can you maintain in production?

In frigate guarantee ±0.02mm on critical bore dimensions for exact fitment. Surface flatness is maintained within 0.005mm for optimal contact. Custom tolerances down to ±0.005mm are available for demanding applications.

How do you ensure consistent conductivity across batches?

Every production run undergoes 100% conductivity testing using 4-wire Kelvin measurement. Our automated systems maintain ±1% IACS conductivity variation. Certificates include actual test values for each shipment.

What quality control processes do you implement?

We perform 17-point inspections including dimensional checks, plating adhesion tests, and microhardness measurements. All testing equipment is NIST-traceable and recalibrated weekly. Full inspection reports accompany every order. 

Do you manufacture custom copper lugs for project-specific designs?
  • Yes, Frigate manufactures custom copper lugs to exact dimensional and electrical requirements.  
  • We support custom bore sizes, palm widths, barrel lengths, plating thicknesses, and alloy grades.  
  • Our engineering team works directly from drawings, CAD files, or specifications.  
  • Prototype and production runs are available for both low and high volumes.  
  • Every design is validated for fit, conductivity, and strength before production.  
What production volumes can Frigate handle for recurring orders?
  • Frigate supports both scheduled repeat production and large-volume programs.  
  • We manufacture from pilot batches to high-volume recurring orders.  
  • Production is aligned with your demand forecasts and delivery schedules.  
  • Controlled workflows ensure consistency across repeat batches.  
  • Full lot traceability is maintained for every shipment.  
Can Frigate support urgent manufacturing requirements and short lead times?
  • Yes, Frigate supports urgent manufacturing requirements and fast-turn projects.  
  • Priority production slots are available for approved drawings and repeat parts.  
  • Machining, plating, and testing workflows are optimized for quick turnaround.  
  • Key production milestones are shared for order visibility.  
  • Delivery timelines are aligned with your project schedules.  
What documents are provided with every manufactured batch?
  • Every batch includes complete material and production documentation.  
  • Standard documents include -  
    • material test certificates  
    • conductivity reports  
    • dimensional inspection reports  
    • plating thickness reports  
    • batch traceability records  
  • Additional compliance documents are available for regulated industries.  
  • Documentation formats can be aligned with your QA requirements.  
How does Frigate ensure consistency in repeat manufacturing orders?
  • Every repeat order follows locked production specifications and control plans.  
  • Machining tolerances and finish standards remain controlled across batches.  
  • Conductivity and dimensional checks are performed on every run.  
  • Serialized batch tracking ensures repeatability.  
  • Our process controls deliver consistent long-term performance.
