Bronze Round Bar 655 Unpolished Mill Finish 0.5in x 12in OnlineMetals

Description

Product Overview

The 655 Bronze Round Bar is a high‑quality silicon bronze rod designed for demanding industrial and scientific applications. Produced by OnlineMetals, this bar features an unpolished mill finish that preserves the natural texture of the alloy while providing a surface ready for machining, welding, or direct installation. With a precise diameter of 0.5 in and a length of 12 in, the bar meets ASTM B98 specifications, guaranteeing consistency in composition, mechanical properties, and corrosion resistance. The material’s composition—copper, tin, and a small amount of phosphorus—delivers a balance of strength, ductility, and resistance to seawater, making it a preferred choice for marine hardware, fasteners, bushings, and shafts. The bar’s H04 temper indicates a soft, annealed condition that is easy to form, bend, or machine without cracking, while still maintaining the durability required for load‑bearing applications.

Usage

Designed for versatility, the 655 Bronze Round Bar excels in environments where corrosion resistance and mechanical resilience are critical. Marine engineers rely on this alloy for propeller shafts, pump housings, and fittings that are constantly exposed to saltwater. In the aerospace sector, the bar is used for bushings and bearing components that demand both strength and the ability to absorb vibrations. Manufacturing facilities employ the bar for custom fasteners, brackets, and tooling components that benefit from its easy machinability and reliable performance under cyclic loads. The unpolished mill finish also makes the bar suitable for applications where a matte aesthetic is desired, such as decorative hardware or architectural elements. Whether you are fabricating a prototype, repairing a marine vessel, or producing a batch of precision components, this bronze rod provides the material integrity and dimensional accuracy needed for success.

FAQ

What does the H04 temper mean for this bronze bar?

H04 indicates that the bar is in a fully annealed, soft condition. This makes it easy to cut, bend, and machine, while still retaining the strength needed for most load‑bearing applications.

Can this bar be welded or brazed?

Yes, 655 silicon bronze is compatible with both welding and brazing techniques. Proper cleaning and the use of appropriate filler materials will produce strong, corrosion‑resistant joints.

Is the unpolished finish suitable for decorative purposes?

The mill finish provides a matte, industrial look that can be used directly in decorative applications. If a higher shine is desired, the surface can be polished or brushed after installation.

How does this product meet ASTM B98 standards?

Each bar is tested for chemical composition, tensile strength, and elongation to ensure it falls within the limits defined by ASTM B98. Certification documentation is available upon request.

What is the recommended storage condition for the bronze bar?

Store the bar in a dry environment, preferably in a sealed container or wrapped in a moisture‑resistant material. This helps maintain its corrosion‑resistant properties over long periods.
