SOURCING OF ALUMINIUM INGOT A7-A8 etc ..
What is Aluminium INGOT A7-A8
Aluminium ingot A7 and A8 are two different grades of aluminium ingots that are produced through the smelting and casting of raw aluminium.
• A7 aluminium ingots typically have a purity level of 99.7% and are used in various industries such as automotive, construction, packaging, and electronics. They are commonly used for further processing to make products such as extrusions, sheet metal, and foils.
• A8 aluminium ingots have a slightly higher purity level, typically around 99.8%, and are used in applications where a higher level of purity is required. They are often used in the aerospace, defense, and high-tech industries for manufacturing critical components that require high strength and corrosion resistance.
Both A7 and A8 aluminium ingots are widely traded commodities on the global market and are produced by various aluminium smelting companies around the world.

SOURCING OF CATHODE COPPER BLOCKS
What is Cathode Copper ?
Copper cathode is a pure form of copper that is used in the manufacturing of various copper products. It is a high-quality copper product that is produced by refining raw copper ore through a process called electrolysis. Copper cathode is also known as electrolytic copper, and it is a semi-finished product that is used to produce copper wire, tubes, and other products.
Standard: GOST 546-2001
Production cycle:
copper-molybdenum ore production;
flotation treatment with obtaining copper concentrate and molybdenum middling product;
copper matte smelting;
converting the copper matte with obtaining blister copper;
blister copper fire refining with copper casting into anodes;
copper anode electrolysis with production of copper cathodes and slime;
Application range:
Cable and conductor products, copper-based alloys production, electrical engineering, copper pipes, motor industry, roofing, etc.
Form and packing:
Cathodes 820 mm x 850 mm x 10 mm, packed as bundles tied up with steel tape, the mass up to 1.5 tons.
X00, Cu – 99.99%
X0, Cu – no less than 99.97%
X1, Cu – no less than 99.95%
The copper cathodes are manufactured as per the GOST 546 requirements ‘Copper cathodes. Specifications’, the chemical composition conforms to the below table.
