Short answer: Silicon metal is a grey brittle semi-metal used as the main alloying element in aluminium, the feedstock for solar polysilicon and the base for silicones, supplied in lump or powder at 97 to 99.5 percent purity so buyers match grade to aluminium, photovoltaic or chemical duty, with certificate and packing per export practice.

What Silicon Metal Is
Silicon metal feeds our Aluminum Supplier and links to our Solar PV Guide et Semiconductor Equipment Guide; density notes are in our Density Comparison Guide.
Properties and Grades
Higher purity serves solar and semiconductor while lower grades serve aluminium, with corrosion notes in our Corrosion Resistance Guide and the renewable context in our Renewable Energy Guide.
Processing
Silicon metal is crushed and milled, with machining in our Machining Guide and cutting in our Cutting Processes Guide; finish is in our Surface Treatment Guide.
Quality and Sourcing
Silicon metal is checked by chemistry, with methods in our Quality Inspection Guide; buyers confirm grade via our Mill Test Certificate Guide and pack per our Export Packing Guide.
