The phrase "average number of materials" is correct and usable in written English.
It can be used when discussing statistics or data related to the quantity of materials in a specific context, such as research, manufacturing, or education.
Example: "The average number of materials used in the construction of each building was significantly higher than in previous years."
Alternatives: "mean quantity of materials" or "typical count of materials".
