Manganese bronze alloys are available in various grades, each with a specific code and set of properties. Some of the notable manganese bronze alloy grades and their corresponding codes are:

C86500 Manganese Bronze: This grade is part of the manganese bronze and leaded manganese bronze alloy family, known for its high strength and durability. It is used in various applications, including casting​​.

C86300 Manganese Bronze (SAE 430B): This alloy is a high-strength, non-heat treatable copper alloy. It is designated with standards such as ASTM B-62, ASTM B-271, ASTM B-505, ASTM B-584, ASTM B-145/4A, SAE 461, SAE J462, SAE 40, AMS 4085, AMS 4855B, and DIN 2.1096.01. It is suitable for applications requiring a good combination of wear resistance and strength​​.

C67300 Manganese Bronze (SAE J463): Often referred to as a manganese brass due to the use of zinc as the alloying element, C67300 exhibits excellent wear and tear characteristics and is easily machinable. It is often used as an alternative for phosphor bronze in demanding applications​​.

UNS C86100 Manganese Bronze: This copper casting alloy is recommended for various casting methods, including centrifugal, investment, plaster, and sand. It is commonly used in marine applications, such as for gears, gun mounts, bushings, bearings, and marine racing propellers​​.

Additional Codes: Other manganese bronze alloy grades include C86200, C86400, C86700, and C99700. These are mentioned in safety data sheets and are used in various manufacturing applications​​.

Each of these grades has specific properties and applications, making them suitable for different industrial and manufacturing needs.

Manganese bronze alloys are known for their excellent corrosion resistance and high strength, making them ideal for use in harsh environments. The addition of manganese to the alloy also increases its wear resistance, making it a popular choice for bushings and bearings.

One of the unique features of manganese bronze bushings is their self-lubricating properties. The material has a natural ability to release small amounts of lubricating oil during use, reducing friction and extending the life of the bearing. This self-lubricating property makes manganese bronze bushings an ideal choice for applications where external lubrication is not possible or desirable.

Manganese bronze bushings are commonly used in applications such as pumps, motors, gearboxes, and other heavy-duty machinery. They are also commonly used in marine applications such as ship propellers and rudders due to their corrosion resistance.

When selecting a manganese bronze bushing, it is important to consider the load and speed of the application as well as any environmental factors such as temperature and exposure to corrosive elements. Proper installation and maintenance are also critical to ensure optimal performance and longevity of the bushing.

Here is a chart table outlining the properties of some common manganese bronze alloys used in graphite bushings:

Graphite bushings made from manganese bronze alloys offer a number of benefits including good wear resistance, high load capacity, and self-lubricating properties. The chart above can be used as a guide to selecting the right alloy for a specific application based on the required strength, hardness, and operating temperature.

Manganese bronze alloys are a popular choice for bearing bushings due to their excellent corrosion resistance, high strength, and self-lubricating properties. When selecting a manganese bronze bushing, it is important to consider the specific requirements of the application and choose an alloy that will provide optimal performance and longevity.

Manganese bronze, a copper-zinc based alloy that also contains small amounts of manganese, aluminum, and iron, is known for its combination of strength, corrosion resistance, and electrical conductivity. These properties make manganese bronze a popular choice for a variety of industrial and manufacturing applications. Some of the most common uses of manganese bronze include:

Components in Heavy Machinery: Manganese bronzes are widely used for components such as bearings, gears, marine propellers, and valve stems. The high strength and resistance to wear make these alloys ideal for heavy-load applications and high-wear environments​​.

Marine Applications: Due to its corrosion resistance and strength, manganese bronze is an excellent material for marine applications. It is used for propeller shafting, rudder bearings, and stern tubes, which are critical components in marine vessels​​.

Valve and Pump Parts: Manganese bronze is also used in the manufacture of valve and pump parts. The alloy’s strength and anti-seizing properties are beneficial in environments where parts are subject to high stress and need to resist seizing or sticking​​​​.
