The melting point of aluminum : 660.37 ° C , and an alloy containing aluminum as its different elements , melting at 482-660 degrees Celsius. Aluminum and Heated from room temperature to the melted alloy state when no color change , determine the welding base material temperature is very difficult, the base material easily burnt or solventsTechnology . Low temperature Aluminium Welding Electrodeswire currently three defined temperature range based. Low temperature aluminum wire temperature range defined currently three main 1,580-620 degrees Celsius temperature aluminum wire . Representative wire ER4047, ER4043 2,380-450 degrees Celsius temperature aluminum wire . Representative wire Q303, WE-Q303B, WE53 , etc. 3,179 degrees Celsius temperature aluminum wire . Representative wire M51, M51-F
