Introduction

Copper alloys are extremely popular as they have strong corrosion resistance to many types of substances and environments. They are resistant to fresh water, steam, marine and industrial atmospheres, non-oxidizing minerals, caustic solutions, organic acids, moist ammonia, halogens, soils, and sulfides.

Copper alloys, however, have poor resistance to inorganic acids. The following datasheet discusses the chemical composition and properties of copper UNS C67410.
