Nickel and Brass reaction?
Nickel and Brass reaction?
I just placed an order for a metric ton of water-cooling components and am checking if the nickel-plated blocks might interact with the brass tubing in my radiator. This will help decide if I need to add any anti-corrosion measures. Any advice would be greatly appreciated!
I just read a detailed piece about Tom's claim that the situation will corrode gradually since the metals are closely positioned on the galvanic scale. He mentioned using distilled water in the loop. This made me think about ways to slow down the corrosion further. The article suggested some anti-freeze products with anti-corrosion benefits, but I was curious about where to purchase them and any potential downsides of adding them. Do you know of any anti-corrosion additives that won’t change the fluid’s color (like the anti-algae ones)?
Brass and nickel in a loop work well; avoid using aluminum when pairing it with nickel, brass, and copper.
I'm checking this myself and I'm currently using a blend consisting of 3% water wetter 97% distilled water and 3 drops of HTH super extended algae guard added every two months, with the entire system being flushed or filled every six months. I'm not sure if it's effective yet since it's only been two months, but I've used water wetter 3% antifreeze 17% distilled water for years. The only problem I've noticed is that temperatures are a couple of degrees higher and the tubing turns green. You can review my build here if you'd like—it explains a lot about the process I went through.
Brass and nickel in a loop are acceptable, but avoid using aluminum with nickel, brass, and copper. Do you have any way to check for actual galvanic corrosion or buildup? Is it mainly based on what you see, or do temperature changes play a role?
I investigated it and believe I should continue using simple distilled water with some pure silver G1/4 plugs for algae, and perform a drain/fill cycle every six months.
