Description
Product Overview
The 655 Bronze Round Bar, commonly known as silicon bronze, is engineered to meet the rigorous standards of ASTM‑B98. With a precise 0.3125″ (1/8″) diameter and a convenient 36″ length, this bar offers a balance of strength and flexibility that is essential for a wide range of industrial applications. The H04 temper provides a moderate hardness, ensuring the material can be machined, formed, and welded without compromising its inherent corrosion resistance. Finished in an unpolished mill condition, the surface retains the natural texture of the alloy, which can be advantageous for certain bonding processes and aesthetic requirements.
Manufactured by OnlineMetals, a trusted supplier in the raw materials sector, this bronze rod is produced using controlled casting techniques that minimize impurities and promote uniform grain structure. The result is a bar that exhibits consistent mechanical properties throughout its length, reducing the risk of weak points during fabrication or service. The product dimensions—36 x 0.3 x 0.3 inches—are packaged to facilitate easy handling and storage, while the weight of 13.6 ounces ensures manageable shipping costs for both small‑scale workshops and larger production facilities.

Usage
Designed for versatility, the 655 Bronze Round Bar excels in marine environments where corrosion resistance is paramount. Its composition resists the aggressive action of seawater, making it an ideal choice for marine hardware such as propeller shafts, pump impellers, and valve stems. In addition to marine applications, the bar is frequently employed in the manufacturing of fasteners, bushings, and custom shafts for machinery that demands both durability and precise dimensional stability.
Engineers and fabricators also appreciate the alloy’s excellent formability, allowing it to be bent, rolled, or stamped into complex shapes without cracking. This property, combined with the H04 temper, enables the creation of components that must endure cyclic loading while maintaining structural integrity. Whether used in aerospace, automotive, or general industrial settings, the bar’s ability to withstand harsh chemicals and temperature variations expands its utility across multiple sectors.
Because the bar meets ASTM‑B98 specifications, it can be confidently specified in projects that require documented compliance, simplifying the approval process for quality‑assured procurement. Its size and finish also make it suitable for prototyping, where rapid iteration and testing are essential. By selecting this bronze round bar, manufacturers can reduce lead times and avoid the need for additional surface treatments, as the mill finish is often sufficient for many functional applications.

FAQ
What does the H04 temper indicate?
H04 denotes a temper that has been strain‑relieved, providing a moderate hardness suitable for machining and forming while retaining good ductility.
Can this bronze bar be welded?
Yes, 655 silicon bronze is weldable using standard welding techniques such as TIG or MIG, and it maintains its corrosion‑resistant properties after welding.
Is the unpolished mill finish suitable for all applications?
The mill finish is ideal for many functional uses where a smooth, polished surface is not required. For aesthetic or specific surface‑finish needs, additional polishing can be performed.
How does this product meet ASTM‑B98 standards?
Each bar is tested for chemical composition, tensile strength, and dimensional accuracy to ensure it falls within the limits defined by ASTM‑B98, providing reliable performance across applications.
What is the typical lead time for delivery?
OnlineMetals maintains inventory of this item, allowing most orders to be shipped within 1‑2 business days after purchase, subject to location and carrier availability.
