AZ61A (also referred to as ZA61 or ERAZ61A) is a premium magnesium-based welding filler metal classified under AWS A5.19 ERAZ61A specification. It represents the industry standard for joining wrought magnesium alloys, offering an optimal balance of weldability, mechanical strength, and corrosion resistance.

Key Identifiers:

AZ61A is meticulously engineered with a precisely controlled chemical composition designed to match the metallurgical properties of common wrought magnesium alloys:

Element	Content (wt.%)	Function
Magnesium (Mg)	Balance (92-93%)	Base metal providing lightweight matrix
Aluminum (Al)	5.8 – 7.2%	Primary strengthening element, improves corrosion resistance
Zinc (Zn)	0.40 – 1.50%	Enhances strength and hardness, improves castability
Manganese (Mn)	0.15% min	Improves corrosion resistance, refines grain structure
Beryllium (Be)	0.0002-0.0008%	Reduces oxidation during welding (trace level)
Silicon (Si)	0.05% max	Controlled impurity
Copper (Cu)	0.05% max	Strictly limited to prevent corrosion
Iron (Fe)	0.005% max	Critical impurity control
Nickel (Ni)	0.005% max	Strictly limited to prevent corrosion

3. Physical & Mechanical Properties

Property	Value	Significance
Melting Point	600°C (1,112°F)	Low heat input required, minimal distortion
Density	1.78 g/cm³	35% lighter than aluminum, 78% lighter than steel
Ultimate Tensile Strength	280 N/mm² (40 ksi)	Matches wrought AZ61A base metal
Yield Strength (0.2%)	190-240 N/mm²	Excellent load-bearing capacity
Elongation	9-15%	Good ductility for structural applications
Brinell Hardness	60 HB	Balanced hardness for machining
Thermal Conductivity	78 W/(m·K)	Rapid heat dissipation during welding
Coefficient of Thermal Expansion	26 × 10⁻⁶/K	Similar to base magnesium alloys
