Name: China High Strength Semi-circular Head Pure Iron Rivet Manufacturers Suppliers Factory - Beilun Jubang Tech
Brand: Beilun
SKU: 256872091

Product Overview

High Strength Semi-circular Head Pure Iron Rivet is engineered for reliability in high-stress applications where durability and precision matter most. Crafted from pure iron, this rivet offers exceptional resistance to corrosion, making it suitable for harsh industrial conditions. The semi-circular head design provides a flush, secure fit while distributing load evenly, minimizing failure risks.Made from ultra-pure iron (99.8–99.9% Fe), these rivets combine exceptional mechanical strength with a smooth semi-circular head design, ideal for aerospace, automotive, and heavy machinery assembly.

Key Features

- Ultra-High Purity: 99.8–99.9% Fe with ultra-low impurities (C ≤0.01%, S ≤0.005%).

- High Tensile Strength: 350–450 MPa, ensuring reliable load-bearing capacity.

- Corrosion Resistance: Natural oxidation resistance enhanced by optional zinc plating.

- Precision Design: Semi-circular head reduces stress concentration and improves aesthetics.

Applications

Industry	Use Case	Key Benefit
Aerospace	Aircraft panel assembly	Lightweight, vibration-resistant fastening.
Automotive	Chassis and engine components	High shear strength for dynamic loads.
Construction	Structural steel connections	Weather-resistant performance in outdoor environments.
Industrial Machinery	Heavy equipment assembly	Fatigue-resistant under cyclic stress.

Manufacturing Process

1. Cold Heading: Precision cold forging ensures consistent rivet geometry and strength.

2. Heat Treatment: Annealing at 700°C to optimize ductility and stress relief.

3. Surface Coating: Electroplating or passivation for enhanced corrosion resistance.

4. Quality Inspection: 100% dimensional checks and tensile testing (ISO 898-1).

Advantages vs. Standard Rivets

Feature	Beilun Pure Iron Rivet	Conventional Steel Rivet
Corrosion Resistance	No coating required for basic use; optional coatings extend lifespan.	Requires galvanizing to prevent rust.
Weight	10% lighter than steel equivalents.	Heavier, increasing assembly weight.
Thermal Conductivity	Better heat dissipation, reducing thermal stress.	Lower thermal stability.
Cost Efficiency	Longer lifespan reduces replacement frequency.	Higher maintenance costs over time.

Quality Assurance

- Certifications: ISO 9001, ASTM F468 (nonferrous fasteners), RoHS compliant.

- Testing: Salt spray testing (ASTM B117), tensile strength validation, and metallographic analysis.

- Traceability: Laser-marked batch numbers for full production history.

Package

Pure iron is typically packaged with rust-preventive oil, wrapped in plastic film, and secured with plastic or metal straps. It is then placed on wooden pallets or in wooden crates, sometimes using moisture-proof paper or vacuum packaging for extra protection during transportation and storage.
