Bronze Round Bar 655 Unpolished Mill Finish H04 1in x 24in

Description

Product Overview

The 655 Bronze Round Bar, supplied by OnlineMetals, is a premium silicon bronze alloy engineered for demanding industrial applications. With a precise 1‑inch diameter and a convenient 24‑inch length, this rod provides a versatile size that fits a wide range of mechanical designs, from custom fasteners to marine components. The material is delivered in an unpolished mill finish, preserving the natural texture of the alloy while allowing for post‑processing such as machining, polishing, or coating according to specific project requirements.

Manufactured to ASTM‑B98 specifications, the 655 bronze composition offers a balanced blend of strength, ductility, and corrosion resistance. The alloy contains a controlled amount of silicon, which enhances its resistance to seawater and other aggressive environments, making it an ideal choice for marine hardware, offshore structures, and any application where exposure to saltwater is a concern. The H04 temper designation indicates that the bar has been cold‑worked to achieve a higher tensile strength without compromising its inherent toughness.

Beyond its mechanical properties, the 655 Bronze Round Bar exhibits excellent formability, allowing engineers and fabricators to bend, shape, and machine the material with relative ease. This flexibility reduces manufacturing time and cost, especially when producing complex geometries such as bushings, shafts, and custom‑fit components. The bar’s consistent dimensions—maintained within tight tolerances—ensure reliable fitment across multiple production runs, minimizing material waste and rework.

OnlineMetals sources its bronze from reputable smelters and conducts rigorous quality inspections at each stage of production. Each bar is inspected for dimensional accuracy, surface integrity, and chemical composition, guaranteeing that the final product meets the exacting standards required by professional engineers and hobbyists alike. The packaging dimensions of 24 × 1 × 1 inches and a weight of approximately 5.82 pounds provide a compact and manageable unit for shipping and handling.

In addition to its technical specifications, the 655 Bronze Round Bar is supported by comprehensive documentation, including material test reports and compliance certificates. These documents facilitate easy verification of material properties for regulatory compliance, quality assurance audits, and project documentation. Whether you are designing a new marine propulsion system, fabricating high‑performance fasteners, or constructing durable bushings, this bronze round bar delivers the reliability and performance you need.

Usage

Marine hardware manufacturers frequently select 655 bronze for its superior resistance to corrosion caused by saltwater exposure. The alloy’s ability to maintain structural integrity in harsh marine environments makes it a preferred material for propeller shafts, pump impellers, and valve components that operate continuously under the stress of seawater. Its unpolished mill finish can be left as‑is for applications where a natural, rugged appearance is desired, or it can be machined to a smoother surface for aesthetic or functional reasons.

In the fastener industry, the 655 Bronze Round Bar serves as a reliable source material for producing bolts, screws, and custom‑shaped fasteners that demand both strength and corrosion resistance. The H04 temper provides a higher tensile strength, ensuring that fasteners can withstand significant loads without deformation. Engineers often appreciate the alloy’s ability to be heat‑treated or annealed after machining, allowing for fine‑tuning of mechanical properties to match specific load requirements.

For bushings and bearing applications, the combination of hardness and ductility in 655 bronze offers a low‑friction surface that reduces wear and extends service life. The material’s inherent lubricity, especially when paired with appropriate lubricants, minimizes the need for frequent maintenance. Its compatibility with a variety of shaft materials, including steel and aluminum, further enhances its versatility in rotating equipment and mechanical assemblies.

Beyond marine and fastener contexts, the 655 Bronze Round Bar is suitable for artistic and decorative projects where a warm, metallic hue is desired. Sculptors and metal artists value the alloy’s workability, allowing them to shape intricate forms while retaining a durable finish. The bar’s size makes it an excellent starting point for custom art pieces, ornamental hardware, or bespoke architectural elements that require both aesthetic appeal and structural resilience.

FAQ

What does the H04 temper designation mean for this bronze bar?

H04 indicates that the bar has been cold‑worked to increase its tensile strength without sacrificing ductility. This temper is suitable for applications that require higher load capacity while still allowing the material to be machined or formed as needed.

Is the unpolished mill finish suitable for all types of machining?

Yes, the mill finish provides a clean, uniform surface that can be machined, drilled, or turned using standard metalworking tools. If a smoother surface is required for aesthetic or functional reasons, the bar can be polished or coated after machining.

Can this bronze bar be heat‑treated to modify its properties?

The 655 bronze alloy can be annealed after machining to relieve internal stresses and improve ductility. Heat‑treating should be performed according to metallurgical guidelines to avoid compromising the alloy’s corrosion resistance.

Does the product meet any specific industry standards?

Yes, the 655 Bronze Round Bar conforms to ASTM‑B98 specifications, ensuring that its chemical composition, mechanical properties, and dimensional tolerances meet recognized industry benchmarks for bronze alloys.
