2. Понимание 5083 Extra-wide Aluminum Coils for Containers

2.1 Что такое 5083 Алюминиевый сплав?

5083 aluminum is a 5xxx series aluminum-magnesium alloy.

It contains magnesium as the main strengthening element and also includes manganese and chromium for structural stability.

It cannot be strengthened by heat treatment; вместо, rolling and strain hardening control its mechanical properties.

5083 is commonly used in shipbuilding, transport vehicles, сосуды под давлением, морские сооружения, rail cars, and container systems because it combines strength, устойчивость к коррозии, и свариваемость.
