JIS H4120 Grade 2017: 3/8 Hard Aluminum Alloy for Superior Strength and Machinability

Aluminum JIS 2017 is a heat treatable wrought alloy that offers decent strength, ductility, and good machinability. Aluminum JIS 2017 offers more strength than Aluminum 2011, and has fair workability and corrosion resistance. As with many aluminum alloys, Aluminum JIS 2017 should not be welded as it reduces the alloy’s corrosion resistance.
