JIS H4000 Grade 5005 H18: Premium Low‑Density Aluminum Alloy
Aluminum JIS 5005 is a lean aluminum magnesium alloy with low density and excellent thermal conductivity. This medium strength non-heat-treatable alloy is known for its corrosion resistance in alkaline marine situations. Aluminum JIS 5005 is readily machinable, and can be welded using TIG and MIG methods. It is important to note that anodizing is a critical part to how Aluminum JIS 5005 is used.
