Specific projects requiring specific alloys can become complicated with different local and international standards. That’s why correctly translating domestic and customary specifications to worldwide foreign specifications is important. The charts with aluminum and zinc alloys mentioned below are an easy way to understand the differences between the most popular specification standards.
Aluminum alloys have wildly varying applications across the industry. And being one of the most used elements, almost all standards have designated specifications.
