How should I choose between 6060 and 6063?

Consider section, temper, mechanical properties, appearance and manufacturing capability together. The alloys are not automatically interchangeable; use the drawing and product standard.

Should 5083 always be selected for marine exposure?

No. Product form, temper, corrosion risk, welding procedure and design standard govern selection. Another alloy may suit a project requiring extrusion.

Can different alloys be welded together?

Some combinations can be welded with suitable filler and a qualified procedure. A welding engineer must assess the heat-affected zone, cracking and corrosion risks.
