Silver Brazing Alloys for Tungsten Carbide Tipped Tools
PRODUCT
CODE
STANDARDS
PRODUCT EN 1044
Universal brazing alloys suitable for brazing of any steel, copper and copper alloys, nickel and nickel
alloys. When brazing stainless steel, zinc content of these alloys may cause corrosion.
Overheating during brazing process may cause highly toxic cadmium fumes.

All alloys in this group are suitable for brazing of any steel, copper and copper alloys, nickel and nickel
alloys. When brazing stainless steel, zinc content of these alloys may cause corrosion.
Tin containing cadmium-free silver brazing alloys are developed to replace the silver alloys with cadmium.
Ternary alloys are favorable for dynamic operations.

FORTEBRAZE 045 ve FORTEBRAZE 055 çelik, bakır
alaşımlarının birleştirilmesinde gümüş içeren sert lehim
alaşımlarıyla kullanılan, toz formundaki dekapanlardır. Gerektiğinde
su ile karıştırılıp pasta formunda da kullanılabilir. Sert lehim işlemi
otomatik ise FORTEBRAZE 045, manuel ise FORTEBRAZE 055
kullanımı önerilir. Universal gümüş sert lehimi olan FORTEBRAZE
055'in kullanım sıcaklık aralığı 550-800 °C’dir.
