Aluminum Wire / Rod & Bar for Fastener Manufacturing

Fastener manufacturers have very specific demands on their raw material. Consistent grain structure, tight dimensional tolerances, reliable surface quality, and predictable cold heading or cold forging behavior — these are the things that keep your production line running smoothly and your scrap rate low.

Taiwan Ye Fong Aluminium produce aluminum hot-rolled Finished Wire/Redraw Rod and straight bar to fastener manufacturers mainly across the aerospace and automotive industries. We are one of the few aluminum mills in Taiwan using a hot rolling process rather than traditional continuous casting, which results in a finer, more uniform grain structure and better formability for cold heading and cold forging fastener applications.

Our aluminum wire/rod is available from 2mm to 32mm in diameter, with surface shaving available in-house. On-line eddy current inspection and ultrasonic testing are performed as standard.

Why Hot Rolling Makes a Difference

Most aluminum wire rod in the market is produced by continuous casting and rolling, which can lead segregation layers and inconsistent microstructure. Our aluminum hot rolling process starts from homogenization-treated billets, which eliminates segregation and delivers following benefits :

• Finer and more uniform grain structure
• Better cold heading and cold forging formability
• More consistent mechanical properties batch to batch
• Lower risk of cracking ratio during downstream forming operations

Fastener Aluminium Alloys FAQ

Q1: Why should fastener manufacturers choose hot-rolled aluminum wire/rod over continuous casting? 

A1: Aluminum hot-rolling process eliminates segregation layers and inconsistent microstructures commonly found in traditional continuous casting. By starting from homogenization-treated billets, Taiwan Ye Fong Aluminium delivers a finer, more uniform grain structure that provides superior formability and zero welding joints for high-performance cold heading and cold forging fastener manufacturing.

Q2: What are the best aluminum alloy materials for manufacturing aerospace rivets and structural fasteners? 

A2: The most recommended aluminum alloys for aerospace fasteners are 2024, 7075, and 5056. Alloy 2024 is widely used for solid rivets and structural bolts due to its high strength and fatigue resistance. Alloy 7075 provides maximum load-bearing capacity for aircraft collar fasteners, while Alloy 5056 serves as the standard for exceptional corrosion resistance.

Q3: Which aluminum alloys are optimized for automotive rivet nuts and structural bolts?

A3: Aluminum 6061, 6056, and 6082 are the workhorse alloys engineered for automotive fastener applications. They offer an optimal balance of good mechanical strength, excellent corrosion resistance, and highly predictable cold heading behavior, making them ideal for high-volume automotive rivet nuts and thread inserts.
