CPC v2.1 Code: 4135

About base metals clad with silver, and base metals, silver or gold clad with platinum, not further worked than semi-manufactured

cpc code 4135 covers a range of semi-manufactured products that involve the cladding of base metals with precious metals like silver and platinum. These materials find widespread use in various industries, from jewelry and decorative arts to electronics and industrial applications. The ability to combine the durability and affordability of base metals with the aesthetic and conductive properties of precious metals makes this industry an important contributor to the global economy.

Production process

The production of materials under cpc code 4135 typically involves a process known as cladding. This involves bonding or fusing layers of different metals together, with the base metal serving as the core and the precious metal forming an outer layer. Common techniques used in this industry include roll bonding, explosion bonding, and electroplating. These methods allow for the creation of composite materials that exhibit the desired properties of both the base and precious metals.

Production inputs

The main inputs required for the production of cpc code 4135 materials include base metals such as 4101 Iron and steel, 4102 Copper, and 4103 Nickel, as well as precious metals like 4111 Silver and 4112 Gold. Additionally, specialized machinery and equipment for the cladding process, as well as various chemicals and consumables, are essential inputs for this industry.

Production outputs

The primary outputs of cpc code 4135 are semi-manufactured products that combine base metals with precious metals. These materials can be used in a wide range of applications, including 4136 Articles of jewellery and parts thereof, 8542 Electronic integrated circuits, and 8543 Electrical machines and apparatus, having individual functions, not specified or included elsewhere in this chapter. The versatility of these clad materials makes them valuable inputs for numerous industries within the broader economy.
