Description

It is boron containing flux in form of tablets
used for oxygen and hydrogen removal from copperbased
alloys. The flux is suitable for pure copper and all
copper-based alloys (brass, bronze, others). The tablets
release a quantity (around 90% of tablet weight) of boron
in melt. Well known that boron is one of the most effective
deoxidizer for copper without harmful effect of reducing
the electrical conductivity. Also the addition of boron in
copper-based alloys is the grain refining effect. As result,
the boron containing flux improves the mechanical and
physical (first of all electrical conductivity) properties of
pure copper and copper-based alloys.

Applications

Oxygen and hydrogen removal operation
in pure copper and copper-based melt under melting /
holding procedure. Improving the mechanical properties
of pure copper and copper-based alloys for wide range of
casting techniques (continuous casting for electric wire
production, high pressure die casting, low pressure die
casting, gravity casting in permanent and sand molds,
others) and different furnace types.

Method of use

1. The boron containing tablets introduce in melt by
degassing plunger tool under melt surface to the bottom
of furnace crucible or furnace hearth.
2. The temperature of treatment must be above 900°С.
3. The degassing plunger must be in melt till ending of
reaction.
4. After reaction the melt rest time must be 1-3 minutes.
5. The melt can be pouring after skimming the dross.
