Ni-based Amorphous Brazing Foils

DESCRIPTION

This amorphous brazing foil is primarily made of nickel and copper. It has low environmental impact because it does not contain organic binders. Being thin and resistant to corrosion, the material is suitable for the brazing of heat exchangers.

Features:

Amorphous brazing filler metal has the following characteristics.
Toughness, flexibility, 100% metal
Melts quickly over a narrow temperature range
Strongly bonded with few voids
Can be installed between joining parts with high precision
Economical and efficient (compared to powder brazing filler metal)
Assembly process can be reduced
No contamination of the environment or brazing furnace
Easy to punch and bend

Reducing the amount of brazing filler metal

Since it is in the form of a foil with a thickness of 25 to 40 μm,
the amount used can be reduced by approximately 50% compared to paste,
contributing to lower brazing material costs.

Comparison of usage reduction rate

(Compared to our company)
Filler metal	Filler thickness (μm)	Net filler usage amount (g)	Usage reduction rate (%)
BNi-15 paste	–	3.308	100
MBF67 foil	38.1	2.309	30
MBF67 foil	25.4	1.560	53

Fewer voids at brazed joint

Since solder foil does not contain a binder like paste material, there are almost no voids (cavities) formed in the bonding layer due to the binder removal process, resulting in a highly reliable bonded product.
