Bronze Round Bar 655 Unpolished (Mill) Finish 0.5″ x 24″ OnlineMetals

Description

Product Overview

The 655 Bronze Round Bar is a high‑quality silicon bronze rod engineered to meet ASTM‑B98 specifications. With a precise 0.5″ diameter and a convenient 24″ length, this bar provides a balance of strength, formability, and corrosion resistance that makes it suitable for a wide range of industrial applications. The unpolished mill finish retains the natural texture of the alloy, offering a surface that is ready for machining, welding, or further finishing processes. OnlineMetals sources the raw material from reputable mills, ensuring consistent composition and mechanical properties across every piece.

Key material characteristics include a copper‑tin‑zinc base with a small amount of phosphorus, which contributes to the alloy’s excellent resistance to seawater and other aggressive environments. The H04 temper indicates that the bar has been cold‑worked to a moderate degree, delivering a good combination of tensile strength and ductility. This makes the bar ideal for components that must endure cyclic loading, such as shafts, bushings, and fasteners.

Packaging dimensions are 24 x 0.5 x 0.5 inches, weighing approximately 1.46 pounds, which simplifies handling and storage. The product is identified by the model number 67866 and is readily available for immediate shipment from OnlineMetals’ inventory.

Usage

Designed for marine hardware, the 655 Bronze Round Bar excels in environments where exposure to saltwater and humidity is a concern. Its corrosion‑resistant properties make it a preferred choice for boat fittings, propeller shafts, and underwater fasteners. In addition to marine applications, the bar is frequently used in the manufacturing of precision bearings, gear components, and custom mechanical assemblies that require a reliable, non‑magnetic material.

Engineers and fabricators appreciate the bar’s ease of machining. The unpolished finish can be quickly turned, milled, or drilled to exact dimensions without excessive tool wear. This reduces production time and cost, especially in small‑batch or prototype projects where flexibility is essential.

Because of its resilience and formability, the bar is also suitable for artistic and decorative purposes, such as custom sculptures, ornamental hardware, and architectural accents that benefit from a warm, metallic appearance.

FAQ

What does the H04 temper mean for this bronze bar?

H04 indicates that the bar has been cold‑worked to a moderate degree, which enhances its tensile strength while maintaining good ductility. This makes the material suitable for components that experience both static and dynamic loads.

Is the unpolished mill finish suitable for welding?

Yes, the mill finish is designed to be weldable. The surface may require cleaning to remove any oxides before welding, but the alloy’s composition supports strong, reliable welds when proper techniques are used.

Can this bronze bar be used for marine fasteners?

Absolutely. The 655 silicon bronze alloy is specifically formulated for marine environments, offering high resistance to seawater corrosion, making it an excellent choice for fasteners, fittings, and other marine hardware.

What is the typical tolerance on the diameter?

OnlineMetals maintains a diameter tolerance of ±0.001″ for the 0.5″ round bar, ensuring consistent fit and performance across all units.
