Oilless wear plates are commonly made of bronze material with solid lubricant. The chemical composition of this material typically includes copper, aluminum, iron, manganese, and zinc, with varying percentages of each element.

In the case of the composition you provided, the oilless wear plate would have the following chemical composition:

• Copper (Cu): 60-66%
• Aluminum (Al): 5.0-7.5%
• Iron (Fe): 2.0-4.0%
• Manganese (Mn): 2.5-5.0%
• Zinc (Zn): 17.5-31.5%

The copper content in this composition provides the wear plate with excellent thermal and electrical conductivity, as well as good corrosion resistance. The addition of aluminum enhances the wear plate’s strength and hardness, while also increasing its resistance to wear and tear. Iron is added to improve the wear plate’s durability and toughness, and manganese helps to further strengthen the material. Finally, zinc is added to improve the wear plate’s resistance to corrosion.

The solid lubricant in the bronze material allows for oilless lubrication during operation, reducing maintenance requirements and improving overall efficiency. The resulting material is highly durable, wear-resistant, and able to withstand heavy loads and high-speed operation.

In summary, the chemical composition of oilless wear plates made of bronze with solid lubricant typically includes copper, aluminum, iron, manganese, and zinc in varying percentages. These elements work together to provide the wear plate with excellent thermal and electrical conductivity, strength, durability, wear resistance, and corrosion resistance, while the solid lubricant allows for oilless lubrication during operation.
