Summary for fe-cr-al wire brightness improvement Discussion
Fe-Cr-Al alloy wire brightness improvement is the core question here: Viraj Desai of Queensland, Australia asks whether a bright dip process can be used to improve the appearance of 0.914 mm heating wire elements made from 1.6 mm Fe-Cr-Al wire drawn by a wet wire drawing process. He is specifically looking for the acids or chemical treatment that might be used, and notes that he is new to the chemistry involved. The excerpt provided contains only the question and no posted answers, so there is no thread-based recommendation to summarize beyond the request itself. Based on the source shown, the discussion is about whether a bright dip is suitable for Fe-Cr-Al heating wire and what acid chemistry, if any, would be appropriate.
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.
