Bronze Round Bar 642 HR50 0.75″ x 12″ Unpolished – OnlineMetals

Description

Product Overview

The 642 Bronze Round Bar offered by OnlineMetals is a premium raw material engineered for high‑performance industrial applications. Crafted from aluminum‑silicon‑bronze, commonly referred to as 642 bronze, this alloy combines excellent mechanical strength with superior corrosion resistance, making it a reliable choice for components that demand longevity and precision. The bar measures a precise 0.75 inch (0.75″) diameter and a 12 inch (12″) length, providing a convenient size for a wide range of machining operations. Finished with an unpolished mill surface, the bar arrives ready for further processing such as turning, milling, or drilling, while preserving the material’s inherent properties. It conforms to ASTM B150 and AMS‑4634 standards, ensuring that each piece meets rigorous industry specifications for composition, tensile strength, and dimensional tolerance. The HR50 temper designation indicates a heat‑treated condition that balances hardness and ductility, allowing the material to be machined with ease yet retain the strength required for load‑bearing parts.

Usage

Designed for versatility, the 642 Bronze Round Bar excels in applications where both strength and corrosion resistance are paramount. Typical use cases include the manufacturing of precision gears, valve components, and industrial blots that operate in harsh environments such as marine, chemical processing, or high‑temperature settings. Its excellent machinability enables manufacturers to achieve tight tolerances and smooth surface finishes, essential for high‑speed rotating parts and fluid control devices. Engineers and fabricators in aerospace, automotive, and marine sectors frequently select this alloy for its ability to withstand fatigue stresses while resisting the corrosive effects of seawater, lubricants, and various chemicals. The bar’s dimensions make it ideal for custom‑fabricated parts, allowing users to cut, shape, and finish the material to exact specifications without compromising structural integrity.
