Sliding brings many problems, serious friction and wears, so far, domestic
Most of the above-mentioned enterprises still use traditional oil and grease lubrication but in fact these
Mining conditions have exceeded the scope of oil and grease lubrication, and bearings and other
Biting or galling of friction pairs, causing severe wear and damage to parts, often

However, the above situation still exists.
2. Key technical principles
Inlaid self-lubricating composite material is a new type of extreme pressure-resistant solid lubricant.
A slippery material consisting of a metal substrate with a solid lubricant embedded in holes or grooves in the substrate
Paste composition. During the friction process, the metal substrate bears most of the load.
After friction, the solid lubricant in the hole or groove is transferred or reversed to the friction surface,
Forms a well-lubricated, firmly adhered and evenly covered solid rotor on the friction surface
Film removal, greatly reducing friction and wear. As the friction progresses, the embedded solid
The body lubricant is continuously provided on the friction surface to ensure the friction pair during long-term operation.
Aluminium Bronze Oilless Bearing– a corrosion-resistant metal in seawater, 2.0966 cual10ni5fe4, cual10ni5fe4 equivalent material, C63000 bronze bushing,
Copper-based alloys with aluminum as the main alloying element are aluminum bronze containing iron and manganese elements, and are high-strength heat-resistant bronze.
Marine applications place high demands on their materials. The high salinity of seawater and ocean currents are just two of the many factors that promote corrosion. However, there is an alloy that can withstand the harsh conditions of the ocean.
Corrosion is a nasty partner in the industry. Accordingly, the expectations for materials are high. They must be of high quality bronze oilless parts, as durable and corrosion-resistant as possible – and all at the lowest possible cost. However, it is not worthwhile to save on material procurement.
General aluminum bronze, usually containing less than 11.5% aluminum, sometimes with some iron, nickel, manganese and other elements added. Aluminum bronze can be heat treated and strengthened, and has higher strength than tin bronze and better resistance to high temperature oxidation. Aluminum-copper has good strength and wear resistance. Used to manufacture higher strength screws, nuts, copper sleeves, sealing rings, etc., parts and wear resistance, the most outstanding feature of aluminum bronze is its good wear resistance. Aluminum bronze is aluminum bronze containing iron and manganese elements, with high strength and wear resistance, after quenching and tempering can improve the hardness, with good high temperature corrosion resistance and oxidation resistance. Aluminum bronze has good corrosion resistance in the atmosphere, fresh water and seawater, fair cutability, welding is not easy to fiber welding, and good hot pressing processing.
“Advantages of aluminum bronze self-lubricating graphite bronze bushings in corrosive environments”
Especially in the marine industry, corrosion-resistant bushings for metal components are required, as seawater is the most common corrosion trigger and accelerates the corrosion process. The reason for this is the high content of dissolved salts. They ensure that chemical reactions in the ocean are much faster than on land. In addition, the ocean currents in the water promote erosion-corrosion and cavitation.
Aluminum bronze self-lubricating graphite bronze bushings and its advantages in seawater
One alloy that is particularly resistant to seawater and is often very corrosion resistant is the aluminum bronze alloy bearing. Aluminum bronze alloys consist primarily of copper with 9-14% aluminum added to it. Other metals such as iron, manganese and nickel can be used as additional alloying elements to further enhance certain capabilities, such as sliding properties.
The excellent corrosion resistance of aluminum bronze self-lubricating graphite bronze bushings is attributed to its passive protective film. Compared to other metals, this film forms very quickly and heals quickly in case of injury. This protective layer manifests itself in its typical brown color. Although this is not aesthetically pleasing, the film protects the metal it surrounds. Aluminum is the main reason for the formation of this film. It reacts easily with oxygen in the environment, forming this impenetrable barrier. Because of these properties, this material is especially used in the marine industry.
Although this external protective film does not give a good impression aesthetically, it is not worth cleaning aluminum bronze. This is because the alloy loses its corrosion resistance in a short time and chemical reactions can cause damage to the aluminum bronze, which may then limit its functionality. Therefore, aluminum bronze self-lubricating graphite bronze bushing self-lubricating properties, bearings do not require special cleaning and maintenance-free.
Multiple uses of aluminum bronze self-lubricating graphite bronze bushing products
Due to the seawater resistance of aluminum bronze alloy, it is often used for plant components such as pumps, valves, flanges, pipe fittings, etc. In addition to seawater resistance, the aluminum bronze graphite copper bushing alloy has high strength and hardness, and therefore has good corrosion and erosion resistance. Salt solutions of different concentrations and temperatures do not have a damaging effect on them.
The lack of fresh water has also led to a strong demand for desalination plants. Here too, aluminum bronze self-lubricating graphite bronze bushings oilless bearing products are used for their corrosion resistance. Seawater or brackish water is also used as cooling water for industrial plants near the coast. Because of its properties,, aluminum bronze alloy is the first choice for self-lubricating bearings in marine industry applications.
Seawater piping systems
As with many aluminum bronze alloys,, aluminum bronze self-lubricating graphite bronze bushings oilless bearing products are particularly useful in propeller and seawater piping systems on ships and offshore platforms. In addition to its resistance to seawater, the, aluminum bronze self-lubricating graphite copper bushing oilless bearing is also insensitive to pitting and crevice corrosion.
