Frequently Asked Questions

Q1: What is the difference between solid and semi-tubular copper rivets? Solid rivets have complete shank cross-section providing maximum strength for structural applications. Semi-tubular rivets have partial hole in shank, require less installation force (40-60% of solid), suitable for lighter-duty assemblies.

Q2: How do I calculate required rivet diameter? General guideline: minimum rivet diameter ≥ 1.5 times thickness of thinnest material. For load calculations: shear capacity ≈ shear strength × cross-sectional area × safety factor (typically 2-4 for static, 4-8 for dynamic loads).

Q3: Can copper rivets be used with aluminum or galvanized steel? Yes, but galvanic corrosion is a concern in wet environments. Use tin-plated copper rivets to reduce galvanic potential, or employ electrical isolation with plastic washers or protective sealants.

Q4: What surface finish should I specify? Bare copper for indoor electrical applications, tin-plated (3-10 microns) for outdoor/marine with 15-25% premium, nickel-plated (5-15 microns) for harsh environments with 30-50% premium, clear lacquer for tarnish protection with copper appearance.

Q5: What is typical lead time? Standard sizes from inventory: 1-2 weeks. Custom specifications: 4-6 weeks including engineering, tooling, production, surface treatment, and testing. Expedited production available with surcharge.
