The copper-containing alloy 77 is a copper-based alloy composed of copper and other elements. Generally, the content of copper in copper-containing alloy 77 is about 77%, and the content of other elements is determined by the specific formula. According to different formulations and application requirements, various elements such as nickel, tin, chromium and zirconium can be added to the alloy containing copper 77 to improve its specific properties, such as strength, corrosion resistance, electrical conductivity and thermal conductivity. This alloy is widely used in the fields of electronics, aviation, aerospace and automation.

Copper's corrosion resistance, plasticity and decorative effect make it an important material in the construction industry, such as plumbing pipes, roofs, doors and windows. Copper and its alloys are widely used in automobile, airplane, ship and other manufacturing industries, such as engines, transmission systems and coolers.
