A7, A8, A9 aluminum ingots are internationally recognized grades used to differentiate aluminum materials with different purities and compositions.

Cathode copper refers to high-purity copper produced through the electrolytic refining process. Cathode copper is characterized by its high electrical conductivity, excellent thermal conductivity, and good formability.

Lead sheet is a common metal material, typically used for protection, isolation, and radiation shielding applications. Lead sheet has a high density and flexibility, making it widely used in the medical, nuclear, construction, and industrial fields. It is effective at absorbing and shielding radiation, hence its widespread use in radiological medical equipment, nuclear power plants, laboratories, and other facilities requiring radiation protection.

Zinc ingot is a metallic product that is primarily composed of pure zinc or high-purity zinc alloys. It is commonly found in the form of solid blocks or cylindrical shapes. It is used in the production of galvanized steel, anti-corrosion materials, electronic components, batteries, zinc alloys, and as an additive in metallurgical processes. Its versatility and favorable properties make zinc ingot a valuable metal material for numerous industrial and commercial uses.
