Nexalloy ER4043A/ER4943 Premium Aluminum TIG Rod

ER4043A/ER4943 ALSI5 ALUMINUM TIG ROD

Nexalloy 4043A/4943 is an alternative alloy to 4043 with 25% higher Ultimate Tensile Strength (UTS) and 50% higher yield strength in the as welded condition. Similar to 4043 it possesses moderate to high strength (35 ksi typical), low melting temperature and high fluidity, low ductility, formability and lower toughness as well as moderate electrical and thermal conductivity. 4043A/4943 may be used to weld 1XXX, 3XXX, 5XXX with less than 3.0% Mg. Common applications include automotive frames, aerospace hardware, bicycles, concrete forms and furniture.

Features:

• Made in Canada to a superior quality
• Optimized for achieving high strength welds in applications where post-weld heat treatment is required
• Approximately 25% higher weld strength than 4043 after welding
  
• Excellent crack resistance
• More ductile than 4043, which helps in dynamic or structural load applications
• Superior corrosion resistance to 4043, though not as good as 5356
• Sold in 10 pound package

Diameters Available and Number of Rods Per Pound:

• 1/16" (1.6mm): 26 - 30
• 3/32" (2.4mm): 12 - 16 (Common Stock)
