Copper Tubular Rivets
Product Overview
Copper tubular rivets are hollow-body fasteners cold-formed from wrought copper alloys C11000 (ETP) and C12200 (DHP). The tubular shank design reduces installation force while providing a large bearing surface for material deformation. These rivets are used in electrical, automotive, and light industrial applications where conductivity, thermal transfer, or non-sparking properties are required. Surface finishes include bright, tinned, and nickel-plated. Dimensional tolerances follow DIN 7338 and ISO 14589, with full material traceability.
Key Features
- Low setting force due to hollow shank geometry.
- High electrical conductivity for ground connections.
- Effective thermal dissipation in electronic assemblies.
- Natural corrosion resistance in mild environments.
- Ductile material allows consistent flaring and clinching.

Use a rivet setting tool with a concave anvil to properly flare the tubular shank. Recommended hole clearance: 0.1 – 0.2 mm over tube O.D. For hard or brittle materials, pre-drill or punch with deburring to avoid shank deformation. Setting force varies with tube diameter and hardness; perform trial sets to determine optimal pressure.
Frequently Asked Questions
Production & Customization
Chance & Union utilizes cold heading and deep drawing processes to produce copper tubular rivets in both standard and custom dimensions. We offer material selection support, prototype development, and high-volume production with full quality control per ISO 9001. Custom finishes, special hardness levels, and non-standard head geometries are available. Contact our engineering team with your technical drawings or performance specifications.
Storage & Handling
- Store in a dry environment with relative humidity below 50% to prevent tarnishing.
- Avoid direct contact with steel tools or acidic materials to prevent galvanic corrosion.
- Use plastic or coated containers; separate by size and finish.
- Implement FIFO rotation; recommended shelf life up to 24 months in original packaging.
- Inspect for discoloration or oxide spots before use; clean with a non-abrasive cloth if necessary.
