Standard: GB/T3190-2020

Chemical Composition (%)

Si	Fe	Cu	Mn	Mg	Cr	Zn	Ti	Al	Others
									Each	Total
≤0.40	≤0.50	1.2-2.0	≤0.3	2.1-2.9	0.18-0.28	5.1-6.1	≤0.20	Rest	≤0.05	≤0.15

Features

Designed for welding high-strength 7075 aluminium alloy, which is known for its excellent mechanical strength and hardness
Due to its high zinc content, welding this alloy presents challenges such as potential brittleness in the weld zone and reduced joint strength compared to the base metal
To avoid defects such cracking, it’s important to carefully control welding parameters such as heat input and travel speed
For best results, welding should be performed while the material is in the T6 temper condition to maintain structural strength and integrity

Available Sizes

Welding wire: 1.2/1.6/2.0/2.4/3.0/3.2/4.0mm
Spool: D270 (7kg)

Applications

Commonly used in the aerospace industry for welding structural components and high-strength fittings
Suitable for mould and fixture fabrication, especially in setups requiring durable and lightweight structures
Ideal for producing parts that operate under high stress in mechanical systems.
Also used in specialized products such as high-end aluminium bicycle frames.
