Product Code:SAE AMS4070
Title:Aluminum Alloy, Drawn, Round Seamless Tubing, 2.5Mg - 0.25Cr (5052-0), Annealed
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope:This specification covers an aluminum alloy in the form of drawn, round seamless tubing.This tubing has been used typically for parts, such as brackets, conduits, and low-pressure fluid lines, requiring good weldability, moderate strength, and good resistance to corrosion, but usage is not limited to such applications.
