Silicon Metal

Copper cathodes are 99.99% pure electrolytic copper plates, the final product of copper smelting and refining. They are the primary traded form of refined copper, used as feedstock by wire rod mills, brass mills, and foundries. LME Grade A cathodes are the global benchmark.

Copper wire rod is a semi-finished product manufactured by continuous casting and rolling of refined copper. It is the starting material for electrical wire, cable, and conductor manufacturing. Wire rod quality is defined by oxygen content, with oxygen-free copper (OFC) commanding premium pricing.

Copper concentrate is a semi-processed ore product containing 20-40% copper, produced by crushing, grinding, and flotation of copper-bearing rock. It is the primary feedstock for copper smelters worldwide. Treatment and refining charges (TC/RCs) are a key element of pricing negotiations.

Copper scrap is recycled copper sourced from electrical cables, plumbing, demolition, and manufacturing off-cuts. Classified by ISRI codes (e.g., Birch for No.1 bare bright, Candy for No.2 copper), it accounts for roughly 30% of global copper supply and is critical for sustainable metal production.

Aluminum ingots are cast blocks of primary aluminum produced from smelting alumina via electrolysis. They are remelted by foundries and fabricators to produce automotive parts, construction materials, and consumer goods. Standard ingots are 99.7% purity, traded at LME prices plus regional premiums.

Aluminum billets are solid cylindrical logs produced by continuous casting, used as feedstock for extrusion presses to create profiles for construction, automotive, and industrial applications. Alloy grades like 6063 and 6061 dominate the market, with billet diameter typically ranging from 127mm to 406mm.
