Manufactured from Monel® K‑500 nickel‑copper alloy, this 1/2" flat washer offers exceptional strength and superior corrosion resistance in extreme environments. The precipitation‑hardened K‑500 material provides higher tensile strength than Monel® 400 while maintaining excellent resistance to seawater, chemicals, and high temperatures. Designed to distribute load evenly and protect mating surfaces, it is ideal for marine, aerospace, oil and gas, and other critical inch‑series applications requiring maximum durability and performance.
