Reliable Metallurgical Grade Silicon Metal 553 Lump

Silicon Metal 553 Lump is a standard metallurgical grade silicon metal with Si ≥98.5%. It is usually selected when your aluminum alloy or metallurgical process needs a cost-controlled silicon addition with regular Fe, Al and Ca control.

We supply Silicon Metal 553 Lump for industrial orders where stable supply, practical furnace handling and current price confirmation are important. Regular lump sizes can be confirmed according to your melting, unloading and packing requirements.

Before quotation, you should confirm the required Fe, Al and Ca limits, lump size, quantity, packing method, destination port and trade term. If your process has stricter impurity requirements, we can also help you compare Silicon Metal 553 with 441, 421, 3303 or other grades before order confirmation.

Silicon Metal 553 is mainly checked by Si content and Fe, Al and Ca impurity levels. The following specification is for regular supply reference.

Final Si, Fe, Al and Ca content should be confirmed by batch COA before shipment.

Silicon Metal 553 Lump is mainly used in aluminum alloy smelting and general metallurgical production. It is used as a silicon source when your process needs to add silicon into the alloy.

In aluminum alloy production, Silicon Metal 553 can be used for cast aluminum, secondary aluminum alloy and other common aluminum alloy systems. It may be used in products such as wheels, engine blocks, construction profiles, machinery parts and other aluminum components.

Silicon Metal 553 is usually used when your production can accept regular Fe, Al and Ca levels. If your alloy formula needs lower impurity limits, you can compare 553 with 441, 421, 3303 or other grades before quotation.

Before using Silicon Metal 553, you should confirm your alloy formula, Fe/Al/Ca limits, lump size and melting method. This helps you choose a grade that fits your production requirement and cost range.

ZhenAn provides a full Mill Test Certificate (MTC) with every shipment. We fully support third-party pre-shipment inspections by SGS or Bureau Veritas (BV) to guarantee the chemical composition meets your exact standards.
