Making use of corrosion-resistant connectors: When joining two dissimilar metals, such as in cases where copper is used with iron pipes, its better to use a soldered or brazed joint instead of a threaded or mechanical one since the former is more durable than the latter. The different Bronze Alloys each have unique resistant qualities to various chemicals that make them the ideal bronze alloys for specific environments. Yacht interiors need to have rounded edges on all surfaces. Metallurgy, Plymouth Tube. However, the series does not provide any information on the rate of galvanic corrosion and thus serves as a basic qualitative guide only. A galvanic series applies to a particular electrolyte solution, hence for each specific solution which is expected to be encountered for actual use, a different order or series will ensue. That is 304 Stainless and it should not be affected by the bronze or brass it is in contact with but it may cause some increase in the corrosion in the bronze. Wood can be left natural, where it will dry and turn grey which is infinitely less work to maintain than the same piece of wood maintained bright by someone who has to constantly oil and varnish that piece of wood. Bronze vs. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. But the important part is it happens slowly and over many years, allowing the owner to blame time and not lack of work for the deterioration of the boat. Satisfactory to 72F (22C)2. of the local environment. The more anodic metal in the combination will corrode, leading to galvanic corrosion of the stainless steel. For example; gold - silver would have a difference of 0.15V being acceptable. Brass, on the other hand, is a copper alloy, so it has a higher resistance to corrosion. ; 5-28-99) .
