Name: ER4047 Aluminum Silicon Solder
Standard: GB/T13815 BA188Si AWS A5.1 ER4047
Explanation: ER4047 silicon alloy aluminum welding wire has a lower melting point of about 500 ℃ and higher fluidity (12% silicon content) than ER4043, and can also be used as a welding material. Can be used as a substitute for ER4043, with higher silicon content, which helps reduce hot cracks and generate higher fillet weld shear strength.
Usage: Commonly used for various difficult welding of aluminum (thin) parts, condensers, air conditioning pipes, high-pressure aluminum pipes, automotive water tanks, fuel tanks, etc.
