Japanese Industrial Standards Data – Aluminum alloy castings
A chart listing aluminum alloys for casting standardized by the Japanese Industrial Standards.
Japanese Industrial Standards
JIS H 5202 : 2010
Aluminum alloy castings
Preface
The chart below is from the Japanese Industrial Standards for aluminum alloys for casting, and is based on the information contained in ISO 3522: Aluminium and aluminium alloys-Castings-Chemical composition and mechanical properties (4th revision) published in 2007. When making adjustments to align it with other international standards and the JIS H 5202 standard that has been in place for some time, no changes were made to the technical content of the parts/materials it pertains to. This standard applies to all aluminum alloys for casting standardized in JIS H 5202 and all types of aluminum alloys for casting standardized in ISO 3522 with the exception of materials for die casting. The material codes listed distinguish between the two.
