Fe-Cr-Al Alloy wire brightness improvement

-----

May 16, 2022

Q. I am an employee working with a wire manufacturing company. We employ Wet Wire Drawing process to redraw Fe-Cr-Al based 1.6 mm wire into 0.914 mm wire. The finer wire is then rolled into Heating Wire Elements which are then used in the domestic appliance industry which uses electric current to generate heat.

I would like to improve the brightness of the heating wire element and wondering if any bright dip process can be used and the acids to be employed?

I am a noob in the chemical reaction process with the metallic alloys.
