trying to understand the risks of a cu component served under the gas containing h2 as a main compound.
Unlike steel, copper and copper alloys cannot be embrittled by hydrogen. There is no negative effect of hydrogen on copper. You don't need to worry.
Only with copper, which contains a lot of oxygen (> 400 ppm), a so-called "hydrogen disease" can develop at temperatures above 500°C: Hydrogen in atomic form can reduce copper oxide inside the copper part and the resulting water vapor can rupture the material.
Thank you very much for your answer, Vadim Verlotski !
Could you please advise me any sources (articles, research groups, companies, cu suppliers, etc. )? As far as I can see there is very limited information available.
Please check "Dies 1967 Copper and Copper Alloys". In the book page 116 the influence of Hydrogen on Copper and it´s alloys is described in detail. Hydrogen can have an influence on Copper and it´s alloys.
It depends what you want to do with it. Molten Copper for example can store a high amount of Hydrogen.
I. Fedorova, DECHEMA Research Institute has a project addressing this very question and is investigating various Cu-containing alloys in H2 atmospheres. If you'd like to know more about our current results and perhaps test your own materials, send me an email: [email protected]
