Magnesium alloys have been used and developed in applications for various motorcycle components and others such as cylinder head cover, crankcase and oil pan due to light weight, high specific strength and recycles ability. However, many of those alloys suffer from inferior die cast ability and high temperature properties, such as creep resistant.
Ryobi limited has developed the creep resistant alloy in order to be utilized for the various motorcycle components and so forth.
The properties of new die cast creep resistant alloy have been introduced. The targets for development of the properties of new alloy are the same creep resistant as aluminum die cast alloys and the same diecastability as ASTM magnesium alloys, such as AZ91D or AM60B alloys. Specific approaches of development with several types of evaluation have been performed for the purpose of fulfillment of this goal.
This paper summarized the more detail of the mechanical properties, high temperature properties and die cast ability of new alloy.
