• Shaved For Ultimate Cleanliness.
• Optimized to reduce smoke and fumes.
• Alloy 4047 was originally developed as a brazing Alloy (BAlSi-4) or (718) to take advantage of its low melting point and narrow freezing range.
• In addition, it has a higher silicon content than 4043, which provides for increased fluidity and reduced shrinkage.
• The alloy produces bright and almost smut free welds. Hot cracking is significantly reduced when 4047 is used as a filler alloy.
