Bronze Round Bar 655 Unpolished H04 Temper 0.5″ x 36″ – OnlineMetals

Description

Product Overview

The 655 Bronze Round Bar offered by OnlineMetals is a premium-grade silicon bronze rod engineered for durability and performance in demanding environments. Crafted from ASTM‑B98 compliant alloy, this bar features a 0.5‑inch (12.7 mm) diameter and a 36‑inch (914 mm) length, providing a versatile size that fits a wide range of applications. The unpolished mill finish preserves the natural texture of the metal, allowing for easy machining, welding, and finishing processes. With an H04 temper, the bar offers a balance of strength and ductility, ensuring it can withstand mechanical stresses while maintaining excellent formability. The alloy’s composition—primarily copper with silicon, tin, and small amounts of iron—delivers superior corrosion resistance, especially in marine and coastal settings where exposure to saltwater and humidity is common. This makes the 655 Bronze Round Bar an ideal choice for components such as marine hardware, fasteners, bushings, shafts, and other critical parts that demand both strength and longevity. Each bar is inspected to meet strict quality standards, guaranteeing consistency in dimensions, surface condition, and material properties across every unit shipped.

Usage

Designed for a broad spectrum of industrial and marine applications, the 655 Bronze Round Bar excels in environments where corrosion resistance and mechanical reliability are paramount. In marine hardware, the bar is frequently machined into custom fittings, propeller shafts, and valve components that must endure constant exposure to seawater without degrading. Its excellent fatigue resistance also makes it suitable for high‑stress fasteners and bolts used in shipbuilding, offshore platforms, and coastal infrastructure. In the manufacturing sector, the bar serves as a raw material for precision‑engineered bushings, bearings, and gear shafts that require tight tolerances and smooth surface finishes. The H04 temper allows the material to be easily turned, milled, or drilled, reducing tool wear and machining time. Additionally, the bar’s resilience makes it a reliable choice for aerospace components, automotive parts, and industrial machinery where both strength and corrosion protection are essential. Whether you are fabricating custom marine equipment, producing high‑performance mechanical parts, or needing a dependable material for prototyping, this bronze round bar provides the versatility and durability required for success.

FAQ

What does the H04 temper indicate?

H04 denotes a temper condition where the bronze has been strain‑released, offering a good combination of strength and flexibility. This makes the material easier to machine while still providing sufficient mechanical performance for most applications.

Is the bar suitable for welding?

Yes, 655 silicon bronze is weldable using standard welding techniques such as TIG or MIG. The unpolished mill finish allows for clean welds, and the alloy’s composition helps maintain corrosion resistance after welding.

Can I use this bar for custom marine hardware?

Absolutely. The alloy’s excellent resistance to seawater corrosion, combined with its strength and formability, makes it ideal for fabricating custom marine components like shafts, fittings, and fasteners.

What is the tolerance on the diameter and length?

Diameter tolerance is typically ±0.005 inch, and length tolerance is ±0.010 inch, ensuring precise dimensions for critical engineering applications.
