what is high silicon aluminum alloy

Silicon has a corrosive effect on cemented carbide. Although the general will be more than 12% Si aluminum alloy called high silicon aluminum alloy, recommend the use of diamond tools, but this is not absolute, silicon content gradually increased the destructive power of the tool is gradually increased. So some manufacturers in the silicon content of more than 8% recommended the use of diamond tools.

What is the comprehensive knowledge of aluminium alloy profile?

Comprehensive knowledge of aluminum alloy profiles:
Aluminium profiles are aluminum materials with different cross-section shapes through hot melt and extrusion.The production process of aluminum profiles mainly consists of three processes: melting, extrusion and coloring (including: oxidation, electrophoretic coating, fluorine spraying, powder spraying, etc.).

Surface Treatment Of Aluminum And Aluminum Alloys

Aluminum alloys are divided into two major categories: wrought and casting alloys. A further differentiation for each category is based primary on mechanism of property development. Many Aluminum alloys  respond to thermal treatment based on phase solubility. These treatments include solution heat treatment, quenching and precipitation, or age hardening.
