Copper
Screws should be made of stainless steel, bronze, or brass. They should have round heads, and flat seats which will not puncture the copper. Galvanically compatible metal washers may be used for additional protection.
These bolts are widely used in electrical equipment and machinery due to their high electrical conductivity and resistance to corrosion. They are commonly found in transformers, generators, motors, and other electrical components
Copper fasteners are the ideal choice for various applications due to their highly corrosion-resistant nature, superior electrical conductivity, and malleability. They have a wide range of operating temperatures up to 700°C and high tensile strength, making them suitable for extreme environments.
