Silicon Aluminium Bronze Chemical Composition, Grade Chart, Tables and Documents

Silicon bronze is a multi-talent alloy which owes its high resistance to the elements, in addition to high strength and good thermal conductivity. The alloy is usually a composition of copper, aluminum, silicon, and not rarely nickel – this alloy is characterized by high strength that makes it useful in wide range of applications, mostly in marine, aerospace, and chemical fields. Typically, S.A. bronzes are recognized as C64200 or C95400 and are made to fit the needs in different grades to wide ranges of environmental conditions. Grade chart is the detailed constituent, mechanical, and recommended use specifications for the different types of alloy. Tables and documents visualizing chemical breakdowns along with requirement specifications for each grade help engineers and manufacturers to pick the best grade for a particular usage, which guarantees maximum performance and durability.

Silicon Aluminium Bronze Chemical Composition Table

Silicon aluminum bronze is an alloy of high strength susceptible to exceptional mechanical properties as well as corrosion resistance. Normal copper-aluminum silicon (Cu-Al-Si) etc. are its major chemical components. However, there may be other trace elements present as well. This type of alloy, in general, is composed of copper in the range of about 81-95%, aluminum between 5-11%, and 1-6% silicon and also, there are variations depending the certain alloy formulation. This alloy offers superior strength, wear resistance and thermal conduction making silicon aluminum bronze an ideal choice for aggressive soil conditions, high temperature environments and structural use in marine applications, aerospace components, and industrial machinery.
