Material Description

Material Number	Material Name	Material Number (single)	Standard	Standard Status	Country	VDA 231-106 classification
3.4144 (WL 3.4144-1 : 1988-01)	AlZn6Mg2Cu2	3.4144	WL 3.4144-1 : 1988-01	Valid	Germany	2.1	1)
1) Remark: The heat-treatable material has a high strength with a satisfactory resistance to stress corrosion cracking and exfoliation cacking. The fracture toughness is high. Cold forming in condition T74xx is impermissible. All usual machining methods may be used. The material shall be protected against surface corrosion. Application: in aircraft construction for integral parts and fittings of larger dimensions
