Well done Vyv Cox - PBO No. 718

I am sure I have seen claims about DZR from an alleged expert in the magazine before that seemed muddled, and didn't match anything I had learned about it elsewhere. Is it the same fellow repeating the same things? I wonder if the magazine editors are aware that his view of this is probably not suitable to present as an authoritative guide?

Its possible that it was written by Trump!
To paraphrase "Vyv's a smart guy, but nobody's ever told me I was wrong before. Bronze is good because manganese is good. DZR has no manganese, it does have arsenic which everyone knows it toxic, so it can't be good. I'm not talking about Blakes. I'm talking about ball valves with shiny balls. Could be anything that makes them shiny, and who knows whats underneath the shiny. Different metals in salt water is bad. Everyone knows that. Perhaps things are complicated. Certainly they will sound like it if I mention stray electrical currents".

Total gibberish.
1. What does manganese have to do with it? Neither bronze, brass nor DZR contain it.
2. Arsenic forms a solid solution in copper alloys. Any could safely be licked.
3. Blakes are DZR. They do not corrode.
4. We know exactly what is beneath the shiny layer (chromium). It is 60/40 brass in bronze and brass valves, DZR in DZR valves.
5. Who mentioned electrolysis?

Bear in mind this guy imports/promotes/sells plastic valves. Rating them against metal valves is a totally different matter. His statement was that there is no place on a boat for DZR.

This is a common issue with a certain surveyor. Every adverse comment of his about DZR is accompanied by photographs of zinc plated valves. DZR is never plated, his comments relate to 60/40 brass.

These constant errors have been pointed out many times to the editors of PBO and YM, by me and others.

The person I took issue with seems to be a colleague or friend.

Vyv, just in case my Trump reference wasn’t clear enough I was not suggesting I in anyway agreed with his points - more that it seemed to be the modern style of trying to win an argument by confusing the audience into submission. When you finally get the printed version you can decide if I overstated his points with my paraphrasing!

No, I understand and thanks for paraphrasing him. Hopefully the next issue will include my article that explains the subject on more detail.

One small historical item included that I found interesting was that the first known use of small arsenic additions to control dezincification was in the boiler of USS Ulysses 1898.

Sounds like the journalist has made a few mistakes.

Is there much hiring and firing in that industry I wonder?

Neither are journalists. One is a surveyor and the other works in the marine trade. Virtually no actual journalists employed by publishers these days apart from the editor
