What is the typical strength and hardness of graphite bronze bushings?

The strength and hardness of graphite bronze bushings can vary depending on the specific material formulation, production process, and other factors. Below are some common graphite bronze bushings strength and hardness ranges:

Hardness:

Generally, graphite bronze bushings have a hardness between HB150 - HB250. For example, the hardness of graphite bushings made of high strength brass can reach about HB210.

Tensile strength:

The tensile strength is usually between 200MPa - 600MPa. The tensile strength of different copper alloy base materials can vary considerably. For example, the tensile strength of graphite bronze bushings made of tin bronze is relatively high, which may be close to 600MPa; while the tensile strength of some common brass materials may be between 200MPa - 400MPa.

It should be noted that the above data is only a general range, the specific strength and hardness values also need to be based on the actual product specifications and manufacturers to determine the data provided. In practical applications, graphite bronze bushings of appropriate strength and hardness should be selected according to the specific requirements of the working conditions.
