Item # BrazeIt 681

Also known as low-fuming bronze, this alloy provides versatility without the higher cost of silver brazing alloys. Works best for induction or torch brazing. Excellent results on ferrous and non-ferrous base metals.

BrazeIt # 681 is a versatile copper brazing alloy suited for the joining of steel, copper, copper alloys, nickel, nickel based alloys, and stainless steel where corrosion resistance is not a major requirement. This copper brazing alloy has gained popularity as an economical alternative to silver brazing alloys.

Most commonly brazed via torch or induction, it is best to keep the heat cycle to a minimum to prevent vaporizing the zinc. Flux is required when brazing with BrazeIt #681.
