HS v2017 Code: 7405

About copper; master alloys

HS code 7405 covers copper master alloys, which are critical components in the production of various copper-based alloys. These master alloys serve as the foundation for creating specialized copper alloys with enhanced properties, such as increased strength, corrosion resistance, or electrical conductivity. They play a vital role in industries ranging from construction and transportation to electronics and renewable energy, making them an essential part of the global economy.

Production process

The production of copper master alloys typically involves melting and alloying pure copper with small amounts of other metals, such as 7401 Copper, unrefined; copper anodes for electrolytic refining, 7402 Copper; unrefined, copper anodes for electrolytic refining, or 7403 Copper; refined and unrefined, copper alloys. The molten mixture is then cast into ingots or other shapes, which are subsequently processed through various techniques like rolling, extruding, or drawing to achieve the desired form and properties.

Production inputs

The main inputs required for the production of copper master alloys include pure copper, as well as small quantities of other metals or elements that are added to modify the alloy's characteristics. Additionally, the production process requires specialized equipment, such as furnaces, casting molds, and metal processing machinery. Energy sources, such as electricity or natural gas, are also essential for the melting and alloying stages.

Production outputs

The primary output of HS code 7405 is copper master alloys, which are then used as the base material for manufacturing a wide range of copper-based alloy products. These alloys are further processed and incorporated into various applications, including 7407 Copper; bars, rods and profiles, 7408 Copper; wire, 7409 Copper; plates, sheets and strip, of a thickness exceeding 0.15 mm, and 7410 (Copper; foil (whether or not printed or backed with paper, paperboard, plastics or similar backing materials, of a thickness (excluding any backing) not exceeding 0.15 mm).
