Deox Copper 0.045″ x 30 lb Spool AWS A5.7 ERCu (Deoxidized and Oxygen Free)

Inweld Deox Copper is a 98% copper filler metal used to overlay, build-up and fabricate electrolytic tough pitch
and oxygen-free copper. The remaining 2% of this alloy is made up of residual elements including phosphorus
and silicon which act as deoxidizing agents to promote sound weld joints. Inweld Deox Copper is chosen over
other copper based alloys in situations where the best combination of electrical conductivity, mechanical properties
and corrosion resistance is required. This filler metal can be used to MIG, TIG and Oxyacetylene weld
copper, copper-alloyed base metals, copper to mild steel, for overlaying steel and for the fabrication of copper
pipes, tanks and fittings. Inweld Deox Copper flows easily and the weld deposits are porosity free and match the
color of copper.
Apply boric acid flux before and during welding. Preheat heavier, thicker sections, but do not overheat as this
will degrade weld properties. This alloy has a very high thermal conductivity rate so overheating will occur
much faster than other base metals. The oxyacetylene flame must be neutral to slightly oxidizing. The oxyacetylene
torch tip size must be one to two sizes larger than the base plate.
