Frequently Asked Questions (FAQ)

Q1. What are copper washers used for?
Copper washers are mainly used for sealing, load distribution, and electrical conductivity in high-temperature or high-pressure applications.

Q2. Why are copper washers preferred over steel or rubber washers?
Copper washers offer superior heat resistance, corrosion resistance, and sealing performance, especially in demanding industrial environments.

Q3. Do copper washers rust or corrode?
Copper does not rust like steel. It forms a natural protective layer that resists corrosion over time.

Q4. Can copper washers be reused?
Annealed copper washers can sometimes be reused after re-annealing, but replacement is recommended for critical sealing applications.
