Table of Fluxes


Mizuno Handy Harman offers a groupe of flux "DIA series" and "HANDY-FLUX series" that have been accepted by many customers since old time.
They are provided by varied optional sales unit such as 100g, 450g, 1kg, 2.5kg, 25kg.

A long storage flux and leftover flux that has dried out might possibly become solid , and their grains become coarser.
The performance as a flux will not change even if it firmed up, but it will takes an effort to restore it to normal paste state, or workability in apllying with brush would deteriorate, so we recommend purchasing by our sales unit suitable for your consumption.

Name Available brazing
temperature  (℃)
base material 
Characteristics and Applications SDS
600~850 Ferrous and non-ferrous metals and their alloys
(excluding light metals) 
This is a general all-round type used for a variety of silver and copper phosphor brazing alloys and post-treatment is done easily using cold or hot water.   PDF
BAg 600~900 High chromium stainless steel, tungsten carbide,
and molybdenum alloys
This flux is good at removing stubborn oxides on tungsten cabide or heat-resistant steel. Its excellent heat resistance makes it suitable for induction brazing when rapid heating is performed.   PDF
DIA-505 BAg、
600~850 Ferrous and non-ferrous metals and their alloys (excluding light metals) The applications are the same as for HANDY-FLUX , but this is more suitable for automatic applying due to moderate viscosity. PDF
DIA-700 BAg、
500~900 Copper, copper alloys, stainless steel, carbon steel, soft steel This is a general, all-round type suitable for silver brazing alloy of most base materials except aluminum and its alloys and magnesium. The heat source can be either a gas torch or induction brazing.   PDF
DIA-707 BAg、
450~850 Stainless steel, carbon steel, copper, copper alloys This general flux is suitable for brazing stainless steel and carbon steel, which is very suitable for induction brazing.  PDF
DIA-800 BAg、
550~950 Cast iron, nickel alloys, copper  This flux is used for brazing under high temperature and brazing of thick materials. It is generally suitable for thick cast iron and soft steel materials and base materials with a high melting point, such as nickel alloys. It has particularly good heat resistance and is suitable for furnace brazing. Combination with ternary brazing alloys can be mainly recommended. PDF
