In this paper, first design and analysis history of full metal CNG cylinders for vehicle are investigated. Next with respect to the CNG worldwide standards, a full metal type cylinder is designed and analysed. Then the numerical analysis results and practical results are compared, and the correctness of the investigation is verified. In the end, the most suitable alloy with respect to the dimensions for the purpose of manufacturing of such cylinders is suggested.
