AG 106, L-Ag34Sn, Silvaloy A34T, BrazeTec 3476. Tin provides good wetting of
difficult metals, e.g. tungsten carbide and stainless steel. For copper and its alloys,
nickel and its alloys, and ferrous alloys. Absence of lead and cadmium allows use
of long heating cycles. Can be used for controlled atmosphere fluxless brazing.
Mostly used for furnace brazing. Pale yellow color. Maximum service temperature
204 °C, intermittently 316 °C. Good alternative to cadmium-containing brazes.
Good wicking. Can be used for induction brazing and flame brazing. Used in
electrotechnics and automotive industry.

BAg-20, AG 204, L-Ag30, Ag 4, Braze 300, Silvaloy A30, Matti-sil 30, BrazeTec
3075, Silver Braze 30. Used in plumbing. For steel and nonferrous alloys with
melting point above 790 °C. For nickel silver knife handles. For electrical
equipment. Gap-filling; wide melting range allows producing fillets. For assemblies
that come in contact with food and dairy. General purpose braze extensively used
for joining copper, brass, bronze, nickel-silver, steel and nonferrous alloys. Suitable
for dip-brazing of wires in electronics; the flow point matches melting point of borax,
which is used as a flux to cover the surface of the molten metal in the pot. Light
yellow color. Maximum service temperature 204 °C, intermittently 316 °C.
