Bronze Round Bar 655 Unpolished H04 Temper 0.75″ x 12″ – OnlineMetals

Description

Product Overview

The 655 Bronze Round Bar is crafted from high‑grade silicon bronze, a material celebrated for its excellent strength, resilience, and superior corrosion resistance. 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 or further finishing processes. The bar conforms to ASTM‑B98 specifications, ensuring consistent chemical composition and mechanical properties across each piece.

Measuring precisely 0.75 inches in diameter and 12 inches in length, the bar offers a compact yet robust profile suitable for a wide range of industrial applications. Its H04 temper designation indicates a heat‑treated condition that balances hardness and ductility, allowing the material to be formed, bent, or machined without cracking. The combination of size, temper, and alloy composition makes this product a versatile component for engineers seeking reliable performance in demanding environments.

OnlineMetals provides detailed packaging dimensions of 12 x 1 x 1 inches and a weight of approximately 1.64 pounds per unit, facilitating straightforward handling and inventory management. The product is identified by the model number 67928 and carries the ASIN B0040X434W for easy reference across e‑commerce platforms. Its ranking as #23 in the Bronze Rods category underscores its popularity among professionals who require high‑quality bronze stock.

Beyond its mechanical attributes, the 655 Bronze Round Bar is designed with sustainability in mind. The alloy’s composition includes copper, tin, and a small percentage of silicon, which together reduce the need for frequent replacement due to wear or corrosion. This longevity translates into lower material waste and reduced operational costs over the lifespan of the component.

Whether you are fabricating marine hardware, constructing fasteners, or producing precision shafts, the 655 Bronze Round Bar delivers the consistency and performance required for mission‑critical projects. Its proven track record in marine and industrial settings makes it a trusted choice for professionals who demand reliability and precision.

Usage

Marine hardware manufacturers often select 655 bronze for its resistance to saltwater corrosion, making it ideal for propeller shafts, pump impellers, and valve components that operate in harsh seawater environments. The bar’s unpolished finish can be left as‑is for applications where a matte appearance is preferred, or it can be machined to tighter tolerances for custom fittings.

In the fastener industry, the alloy’s combination of strength and ductility allows for the production of bolts, screws, and pins that maintain structural integrity under cyclic loading. The H04 temper ensures that these fasteners can be installed without excessive torque while still providing a secure hold, reducing the risk of thread stripping or material fatigue.

For bushings and bearing applications, the 655 Bronze Round Bar offers low friction characteristics and excellent wear resistance. Engineers can machine the bar into cylindrical bushings that support rotating shafts, providing smooth operation and extending the service life of mechanical assemblies.

Fabricators working on custom shafts benefit from the bar’s uniform diameter and consistent material properties, which simplify the machining process and improve dimensional accuracy. The bar can be turned, milled, or drilled to meet exact specifications, enabling the creation of bespoke components for specialized machinery.

Beyond marine and mechanical uses, the alloy’s aesthetic appeal and workability make it suitable for artistic installations, decorative hardware, and architectural elements where a warm bronze tone is desired. Its ability to be polished or left with a natural finish offers designers flexibility in achieving the desired visual effect.
