Copper and aluminum joints are a very sensitive area in electrical installations because the two metals behave differently, and if not handled properly, they can cause overheating, sparking, or even fires. Here’s what you need to know:Problems with Direct Copper-Aluminum Connection 1. Galvanic Corrosion – When copper and aluminum touch directly, especially with moisture present, they form a galvanic cell that leads to corrosion at the joint. 2. Different Expansion Rates – Aluminum expands more t

Steller Sphere on Instagram: "When aluminum hits bronze, especially in the presence of an electrolyte like saltwater, it causes galvanic corrosion, where the aluminum rapidly corrodes (sacrifices itself) to protect the copper-rich bronze, leading to aluminum pitting and eventual failure, though in high-heat casting, it forms a beneficial, strong aluminum bronze alloy with excellent marine and wear resistance. In Marine/Moist Environments (Galvanic Corrosion): • Sacrificial Protection: Aluminum i
