Nickel Aluminium C95800 Bronze Round Bars are used for demanding engineering applications where strength, wear resistance and performance in marine or corrosive environments are important considerations. C95800 is a nickel-aluminium bronze alloy within the copper-alloy family, with aluminium, iron, nickel and manganese contributing to its properties.

For buyers, engineers and procurement teams, selecting the right C95800 round bar involves more than specifying the alloy designation. The required product form, applicable material standard, diameter, length, condition, inspection requirements and documentation should all be confirmed before an order is placed.

This guide explains the material, its verified chemical composition, key characteristics, industrial applications and the important points to consider when sourcing Nickel Aluminium C95800 Bronze Round Bars.

What Is Nickel Aluminium C95800 Bronze?

C95800 is a nickel-aluminium bronze alloy. It combines a copper-rich base with aluminium, nickel, iron and manganese.

The alloy is recognised in ASTM specifications for cast copper alloys. For continuous-cast products, ASTM B505/B505M covers copper-base alloy continuous castings and includes C95800. Copper.org also identifies C95800 under several casting specifications, including ASTM B505/B505M for continuous castings and ASTM B148 for aluminium bronze sand castings.

C95800 is also commonly described as alpha nickel-aluminium bronze. Its alloying system is designed to provide a useful combination of mechanical strength and resistance to demanding service conditions.

When purchasing a round bar, however, buyers should verify that the specific bar product, manufacturing route and applicable standard correspond to the required specification. An alloy designation alone does not establish that every product form is covered by the same standard.

C95800 Bronze Round Bars Chemical Composition

The chemical composition should be checked against the material standard specified for the purchase.

For C95800 continuous-cast material, the ASTM B505/B505M-23 composition published by Wieland Concast is:

Element	Composition
Copper (Cu)	79.00% min
Aluminium (Al)	8.50–9.50%
Nickel (Ni)	4.00–5.00%
Iron (Fe)	3.50–4.50%
Manganese (Mn)	0.80–1.50%
Silicon (Si)	0.10% max
Lead (Pb)	0.03% max

The specification also states that iron shall not exceed nickel and that the nickel value includes cobalt.

This composition is important because the aluminium, nickel, iron and manganese additions contribute to the characteristics expected from nickel-aluminium bronze.

Procurement note: Chemical limits can depend on the applicable product specification. Always use the certificate and governing standard for the actual material being purchased.

Key Properties of C95800 Nickel Aluminium Bronze

High Mechanical Strength

C95800 is used for components exposed to mechanical loading and demanding operating conditions. Published engineering data for ASTM B505 C95800 lists an as-cast tensile strength of 620 MPa minimum and 0.5% proof strength of 276 MPa, with 15% elongation in the referenced condition. These values are condition-specific and should not be treated as universal values for every C95800 bar.

Wear Resistance

Nickel-aluminium bronze is used for components such as bushings, gears, wear plates and worm wheels where resistance to mechanical wear is important. C95800 supplier data specifically lists these among its industrial applications.

Marine-Service Capability

C95800 is used in marine applications including marine hardware, shipbuilding components and valves exposed to seawater service. Material selection still needs to consider the actual seawater chemistry, velocity, temperature, loading and design conditions.

Machinability

C95800 can be machined into engineered components, although its machinability is not comparable with free-machining brass alloys. Wieland Concast gives C95800 a machinability rating of 20 in its published data.

This makes machining parameters and tooling selection important when producing precision components from the material.

Heat Treatment

Nickel-aluminium bronzes can respond to heat treatment, but the applicable treatment depends on the alloy, product form, section size and required properties. Published engineering guidance describes heat-treated C95800 conditions separately from as-cast material.

Therefore, buyers should specify the required condition instead of assuming that one mechanical-property table applies to every C95800 round bar.

C95800 Bronze Round Bars Applications

C95800 is used across several industrial sectors because of its combination of strength, wear performance and suitability for demanding environments.

Marine Industry

Marine applications include:

Marine hardware
Shipbuilding components
Propeller-related components
Shafts
Valves exposed to seawater
Propeller hubs

Published C95800 product data specifically identifies marine hardware, shipbuilding and seawater-contact valves among its applications.

Industrial Machinery

C95800 can be selected for industrial components such as:

Bushings
Gears
Shafts
Wear plates
Worm wheels
Worms
Valve bodies
Machinery components

These applications take advantage of the alloy's combination of mechanical strength and wear-related performance.

Fasteners

C95800 is also listed for fastener applications, including nuts. The suitability of the alloy for a particular fastener should be confirmed against the design, applicable specification and service conditions.

Pickling Equipment

C95800 is listed among materials used for pickling equipment. Actual material selection should account for the particular chemical environment and operating conditions rather than relying on alloy designation alone.

Nickel Aluminium C95800 Bronze Round Bars for Marine Applications

Marine engineering is one of the most important application areas for nickel-aluminium bronze.

Components operating around seawater can experience corrosion, erosion, mechanical loading and wear simultaneously. C95800 is therefore considered for applications such as valves, marine hardware, shafts and propeller-related components.

However, “marine grade” should not be treated as a blanket guarantee of suitability for every seawater application. Engineers should evaluate temperature, seawater velocity, chemical conditions, galvanic interactions, mechanical loading and component geometry before final material selection.

This is particularly important for critical marine components.

Choosing the Right C95800 Bronze Round Bar

When sourcing C95800 round bars, buyers should provide enough information for the supplier to identify the correct material and product.

1. Alloy Designation

Specify:

UNS C95800

and identify the required ASTM or other governing specification.

2. Product Form

Clearly state that the requirement is for a round bar / solid bar if that is the intended product.

This matters because C95800 is available through different casting/product routes, and standards do not automatically apply to every possible form.

3. Diameter

Specify the required outside diameter and tolerance.

For continuous-cast C95800, published supplier information lists solid products from 1/2 inch to 9 inches OD, but commercial availability can vary by producer and product form.

4. Length

Specify:

Random length
Fixed length
Cut length

depending on the project requirement.

5. Condition

Where mechanical properties are important, identify the required material condition or temper and request the corresponding certified properties.

6. Inspection Documentation

Depending on the application, buyers may request:

Material Test Certificate
Chemical analysis
Mechanical test results
Dimensional inspection
Third-party inspection
Heat/batch traceability

The exact documentation should be agreed before production or dispatch.

Nickel Aluminium C95800 Bronze Round Bars Manufacturers and Suppliers

For example, C95400 and C95800 belong to different alloy designations and have different alloying compositions.

C95800 contains significant nickel in addition to aluminium and iron, while C95400 is a different aluminium bronze composition.

For a replacement material, engineers should compare:

Chemical composition
Mechanical properties
Corrosion environment
Wear conditions
Manufacturing route
Applicable standard
Design requirements

A supplier should never substitute one grade for another without customer approval where the specification is critical.
